Metrics details
Co-option of gene regulatory networks leads to the acquisition of new cell types and tissues
are present in most land plants and regulate CO2 exchange
The transcription factor (TF) FAMA globally regulates GC differentiation
FAMA also promotes the development of idioblast myrosin cells (MCs)
another type of specialized cell along the vasculature essential for Brassicales-specific chemical defences
FAMA directly induces the TF gene WASABI MAKER (WSB)
a stomatal lineage-specific direct FAMA target)
synergistically promote GC differentiation
wsb mutants lacked MCs and the wsb scap1 double mutant lacked normal GCs
Evolutionary analyses revealed that WSB is conserved across stomatous angiosperms
We propose that the conserved and reduced transcriptional FAMA–WSB module was co-opted before evolving to induce MC differentiation
how FAMA regulates the differentiation of GCs through its direct targets is largely unknown
the precise components of the GRNs regulating GC and MC development via FAMA
and how each cell identity is differentially regulated are largely unknown
as are the key genes directly regulated by FAMA
Here we describe two direct FAMA target genes that encode TFs: ERF51
which we renamed WASABI MAKER (WSB) after its functional analysis
Genetic and biochemical analyses revealed that FAMA deploys WSB and SCAP1 for GC differentiation
and WSB specifically for MC differentiation
We propose that the FAMA–WSB–SCAP1 GRN had an established function in the differentiation of GCs before being co-opted and reduced to the FAMA–WSB GRN for the differentiation of MCs during evolution
reflecting the neofunctionalization of FAMA and WSB
This study not only advances our understanding of how specialized cells arise during evolution
but also provides insight into the co-option and neofunctionalization of GRNs during evolution
Note that WSB (green) is the only gene directly connected to FAMA (purple)
The only TF genes that are strongly connected with FAMA (as shown by thicker lines) are WSB and SCAP1

suggesting that WSB is a critical downstream target of FAMA for the development of MCs
These results suggest that WSB governs transcriptional networks for the differentiation of both MCs and GCs
in agreement with the WSB expression pattern
these results suggest that WSB can activate the expression of a subset of MC marker genes in various cell types
the promoter fragment was from −1,770 to −1 bp; for proSCAP1(del):GUS

These results suggest that WSB and PAT repress the expression of the guard cell-specific gene SCAP1 in the MC lineage
resulting in the fate specification of MCs
suggesting that these two TFs contribute to the differentiation of GCs at the stage just after final division
Representative confocal images for the ‘unorganized’ category of stomata in wsb scap1 at 21 DAG
Cell walls were stained with propidium iodide
Representative electron micrographs of stomata from the WT (left) and abnormal stomata in wsb scap1 (right)
True leaves from plants at 21 DAG were used
except for WT GCs just after division (14 DAG)
These results suggest that unopen GCs at 14 DAG might have the potential to differentiate
but they failed to properly differentiate into normal GCs
instead differentiating into irregular GCs at 21 DAG
these results suggest that WSB and SCAP1 act synergistically in the differentiation of GCs
These results suggest that CYCD7 can induce random divisions of stomatal-lineage cells in wsb scap1 instead of the symmetric divisions or division along the longest wall previously reported in fama
Statistical significance was tested using ANOVA followed by Tukey–Kramer test (f,h,o
P < 0.05) or a Student’s t-test (g,i,k,l
suggesting that WSB may weakly bind to the FAMA promoter
these results suggest the existence of a positive feedback regulation between WSB and the FAMA–SCRM complex in both MCs and GCs
This feedback is required for the sustained
these results suggest that the WSB–CCS52A1 module is required for MC differentiation
we propose that WSB suppresses the expression of SCAP1 in MCs
The positive feedback loops of FAMA–WSB and WSB–FAMA may support the sustained and/or high expression of WSB in MC lineages
these results suggest that the co-option of WSB might have occurred in the common ancestor of Brassicales
BdFAMA may not activate the AtFAMA promoter
resulting in the loss of WSB in inner tissues
These results suggest that the positive feedback-dependent expression of FAMA in inner tissues was acquired during evolution
these results suggest that the FAMA–WSB transcriptional module may be conserved in this plant order
we propose that Brassicales plant species co-opted the FAMA–WSB module for the evolution of the myrosinase-glucosinolate defence strategy
we discuss the conserved stomatous transcriptional module
and the co-option and neofunctionalization of the stomatal executors
for defence against herbivores in Brassicales
It is an open question whether SCAP1-positive cells in WSB-knockdown lines are phloem parenchyma cells (specifically
even though the development of vascular tissues is different between leaves and roots
scRNA-seq or single-nucleus RNA sequencing analysis of leaf primordia
may provide useful information about the cell lineages and upstream factors of FAMA in inner tissues surrounding future vascular tissues
WSB may be a good target for gene editing to generate Brassicales vegetables/crops without pungency
as gene editing of multiple homologous genes
other direct FAMA targets may play critical roles in other aspects of stomatal development and function
These results suggest that the promotion of GC differentiation is the primary role of FAMA in angiosperms
A stomatal function for WSB and SCAP1 in other species remains to be determined
These results suggest that the binding of WSB to the FAMA locus is transient and/or that WSB indirectly binds to the FAMA locus
Further experiments are required to fully elucidate the detailed binding mode of WSB to the FAMA locus
Future studies will shed light on how WSB and epigenetic regulators work together or independently to maintain sustained FAMA expression
How Brassicales plants established the positive feedback regulation of FAMA is an important question for further investigation
the evolution of cis elements necessary for FAMA binding in the FAMA promoter and the 3D structure of the FAMA–SCRM complex bound to these cis elements should be examined
We also do not exclude the possibility that other inner tissue-specific phytohormones and/or TFs contribute to the expression of WSB with the FAMA–SCRM complex
To clarify the detailed role of CCS52A1 in the differentiation of MCs
live imaging of MC development and their ploidy change using the histone H2B reporter (for example
H2B-GFP) in WT and ccs52a1 mutants is needed in future studies
comparative transcriptome studies of MCs from WT and ccs52a1 are needed to elucidate the comprehensive role of CCS52A1 in MCs using single-cell analysis approaches
Further analysis of other WSB targets will provide a detailed molecular mechanism of MC differentiation
suggesting that the AtWSB promoter is important for the development of MCs and neofunctionalization of WSB
Analyses of the evolution of cis regulatory elements in the AtWSB promoter are needed for future studies
We cannot address a possible neofunctionalization of WSB protein stability in Brassicales
as we used codon-optimized sequences for each WSB homologue tested
which may improve translational efficiency
These two neofunctionalization events of FAMA and WSB are connected by the transcriptional layers between FAMA and WSB
these results suggest that the positive feedback-mediated sustained or high expression of WSB (WSB dynamics) in the MC lineage may have driven the evolution of MCs
we provide evidence here for the co-option and the neofunctionalization of stomatal executors

Mina Shirakawa is leaving Japan and could be making AEW her full-time home
Tokyo Sports reported today that Shirakawa has informed Stardom that she will be leaving the promotion at the end of March for what is likely a full-time move to wrestling in the United States
The report mentioned both AEW and WWE as potential destinations
Shirakawa has already been a regular for AEW while with Stardom
including playing a role in the highly praised storyline between Toni Storm and Mariah May
The report states that the 37-year-old Shirakawa told Stardom of her decision to leave at the end of last year
Shirakawa made her first AEW/ROH appearance in March 2024 and challenged both Storm and May for the AEW Women’s World Championship during their respective reigns last year

Mina Shirakawa expected to join AEW imminently
Having impressed in fleeting appearances for AEW, it looks like Mina Shirakawa is gearing up to make Tony Khan's promotion her new permanent home
As per Fightful Select, Tokyo Sports is reporting that Mina is in the process of wrapping up her current STARDOM run and is expected to head to the United States. Fightful's sources confirmed that the 37-year-old is indeed on her way to AEW
with a press conference planned for later in the week
The outlet was told that this move has been planned for a while
with Shirakawa previously telling Fightful how she was intending to move to America at some point in the future
Having made her in-ring debut in 2018, 2020 saw Mina Shirakawa make her first appearance for STARDOM. Battling a who's who of the promotion in the years since, the Venus' success with STARDOM includes runs as the Future of STARDOM Champion, the Wonder of STARDOM Champion, two stints as one-third of the Artist of STARDOM Champions, and winning the Goddess of STARDOM Championship with a certain Mariah May
On that front, Mariah May's own AEW future has been in the news this week
with the former AEW Women's Champion's current AEW deal due to expire this year
it is believed that AEW will have an extension that they can and will trigger to keep the Glamour #AllElite for the foreseeable future
The first AEW fans saw of Mina Shirakawa was on an April 2024 episode of Dynamite, where she came to the rescue of Mariah May to save her old tag partner from an Anna Jay beatdown
Mina would make her AEW in-ring debut later that month
defeating Jay on the company's Wednesday night flagship
Shortly after that, Shirakawa was inserted into the Mariah May and Toni Storm dynamic
which saw her get a shot at Timeless Toni's AEW Women's Championship at last year's Forbidden Door
she'd later get another crack at the AEW Women's Title
facing Mariah at Winter is Coming in December following May turning on her former partner
much like Mariah had previously turned on Toni
Shirakawa came up short in her quest to win the AEW Women's Championship
Mina Shirakawa has technically wrestled one more match under the AEW banner since then, with that being at the co-promoted Wrestle Dynasty - which featured AEW, ROH, CMLL, and NJPW talent - event in January. There, Shirakawa lost the RevPro Undisputed British Women's Championship to AEW TBS Champion Mercedes Moné in a winner-takes-all match with both of those titles on the line

The in-demand Japanese star broke the news in a video
less than 24 hours after reports surfaced about her plans
After a successful run with AEW last year as part of Timeless Toni Storm and Mariah May’s widely-praised Women’s World title storyline
Stardom’s Mina Shirakawa saw her popularity in the United States skyrocket
and the savvy to know how to use those advantages in a variety of ways
Most figured it was only a matter of time before the “We Want Mina” chants led to the joshi wrestler moving to the United States and signing with one of the big feds based here
Given her history with the company and its roster — and AEW’s ties to Stardom and its fellow Bushiroad-owned promotion New Japan Pro-Wrestling — it would have been somewhat of a shock if that wasn’t AEW
Now, just hours after the first rumors/reports that Shirakawa was leaving Japan for the States and an AEW contract
The 37-year-old from Tokyo has been with Stardom for five years
and has captured several of the promotion’s titles (Shirakawa held Stardom’s secondary singles belt as Wonder of Stardom champion
and is a two-time Artist Of Stardom (trios) & one-time Goddesses Of Stardom (tag) champ)

Escape to the magical snow-covered village of Shirakawa-go
Deep winter in Japan conjures images of crowded ski resorts
steaming hot springs and … not much else
and you’ll uncover enchanting landscapes touched by the silver and white wand of winter
Gifu Prefecture’s historic village Shirakawa-go stands out for its unique scenery: steep
the farmhouses — some of which offer overnight accommodation — glow softly in golden lamplight
wintry Shirakawa-go is truly a sight to behold
Shirakawa-go gained UNESCO World Heritage status in 1995 along with Gokayama in neighboring Toyama Prefecture
The two areas are home to three traditional villages inscribed as part of the World Heritage Site — Ogimachi in Shirakawa-go and Ainokura and Suganuma in Gokayama
Shirakawa-go’s Ogimachi is the most well known of the three and the easiest to access
If losing yourself in timeless townscapes is on your list of things to do
read on for everything you need to know about visiting this exceptional village
Shirakawa-go is an ancient mountain settlement surrounded by forests
The village is well known for its farmhouses built in the distinctive gassho-zukuri style
a construction method featuring roofs that resemble hands joined in prayer
While this type of dwelling originated in the Edo period (1603–1867)
the Hida region shows traces of human life dating back to between 7000 BCE and 2300 BCE.
Sightseeing in Shirakawa-go centers on two areas: Ogimachi
where you’ll find gassho-zukuri houses
It was Ogimachi’s gassho-zukuri architecture that led to its registration as a UNESCO World Heritage Site
The village owes its status — and its traditional townscape — to preservation efforts made by residents after many of the village’s gassho-zukuri houses were lost due to construction and fire in the mid-1900s.
is the largest settlement in the area and is dotted with gassho-zukuri houses
These houses are well adapted to the region’s climate
steep-pitched roofs efficiently shedding winter’s heavy snowfalls and preventing structural damage and collapse
The functional design of gassho-zukuri houses extends beyond sharply sloping roofs — the large windows of the gable ends have a purpose
sericulture was a key industry in Shirakawa-go
and households cultivated silkworms in their multifloor attics
The expansive windows illuminated and ventilated these upper floors
Though gassho-zukuri style houses originated in the mid-Edo period
their historical significance went unrecognized until the latter half of the 20th century
abandonment and submersion in the wake of hydroelectric dam construction had decimated their number
The houses of Ogimachi remain due to the efforts of locals
who formed a preservation society in 1971 to protect the surviving homes
the area had been designated a Preservation District for Groups of Traditional Buildings
paving the way for the World Heritage Site designation of 1995.
The prominence of the Wada family is clear from the farmhouse that bears its name: Not only is Wada House the largest gassho-zukuri residence in Shirakawa-go
including two tatami rooms — with their own special entrance — for the sole use of important visitors
a traditional garden and a fire-resistant earthen storehouse
but many rooms and the attic are open to the public and feature displays of historical items and tools related to the construction of the pitched roof
Visit the house to gain insight into the lifestyle of the family that was once Ogimachi’s largest landowner
a temple of the Jodo Shinshu (True Pure Land) school of Buddhism
located in the head priest’s living quarters — one of Ogimachi’s biggest gassho-zukuri houses
Myozenji has been the village’s principal Buddhist sanctuary for over 275 years and features a two-story thatched gate-slash-bell tower and thatched main hall
tools for silkworm cultivation and other items used by villagers in the past
Those curious about the construction of gassho-zukuri roofs will have much to admire in the attic
as the straw ropes and bindings that hold the roof together are clearly visible
The mountains and rivers of the Shirakawa-go area provide inhabitants with plentiful fresh ingredients
allowing them to develop nutritious and delicious seasonal cuisine
Befitting a town that regularly welcomes foreign nationals — of the 1.7 million visitors to Shirakawa-go in 2023
658,441 were international tourists — many of the restaurants around the village feature English menus
Dine in a gassho-zukuri farmhouse, right in Ogimachi, at Irori
Making full use of the bounty of each season
Irori offers local dishes such as Hida beef grilled with hoba (magnolia leaf) miso
grilled gassho tofu and udon or soba topped with mountain vegetables
A souvenir shop next to the restaurant sells a variety of local sweets and specialty products
as well as grilled Hida beef skewers and mitarashi dango.
Tenkara specializes in Hida beef
Produced from the Japanese black breed of beef cattle
Hida beef is considered one of the finest varieties of Japanese beef and is known for its marbling
Give this regional specialty a taste with one of Tenkara’s set meals
As the restaurant is equipped with in-table yakiniku grills
you’ll get to cook your meat to your very own definition of perfection.
Located opposite Ogimachi’s information center, Shiraogi serves teishoku (set meals) made with locally sourced ingredients like river fish and mountain vegetables
Savor your drink under the thatched roof of a gassho-zukuri house at Ochudo
a conveniently located cafe just a short walk from the Shirakawa-go bus terminal
which maintains the original layout of the house
offers zenzai — a sweet soup made of red azuki beans — with free refills
It should come as no surprise that Purin no Ie (house of pudding) specializes in pudding
established by residents with long ancestral ties to Shirakawa-go
prides itself on its use of high-quality ingredients
Gifu-developed Minomusume strawberries and pristine local spring water
Purin no Ie’s smooth-as-silk nameraka pudding and its award-winning mizu (water) pudding attract visitors from all over Japan
seasonal and village-inspired puddings are also on offer
like gohei mochi pudding with a miso aroma
Shirakawa matcha pudding made with matcha from south-central Gifu’s tea-producing town of Shirakawa and strawberry pudding.

This cozy kissaten serves up a variety of coffee blends and teas, plus assorted sandwiches, cakes and toast. Only a four-minute walk from Wada House, Coffee Shop Hina is the perfect spot to grab a snack before or after checking out Ogimachi’s most well-appointed abode
Get a real feel for life in Shirakawa-go by spending the night in a thatched house. These lodgings are typically furnished with tatami mats and futon, and some even have private onsen. Check the list of available gassho-zukuri properties for an overview of their style of accommodation.
For a taste of omotenashi — Japanese-style hospitality — book a night at a ryokan. The historical Shiroyamakan
built in 1884 and an Important Traditional Building
is an enchanting option that hosts just four groups per night
Shiroyamakan is a fusion of classical Japanese elements and modern Japanese design
a homey retreat where you can sample local seasonal cuisine and soak up the natural beauty and traditional culture of Shirakawa-go.
the snowy Shirakawa-go region gets quite chilly in the winter months
especially as you’ll likely spend a lot of time outside
and we recommend a thermal base layer like Uniqlo’s Heattech
Pack footwear that will keep your toes toasty and your feet comfortable as you walk around town
Although Shirakawa-go is a popular tourist destination for residents of Japan and foreign nationals alike
it’s important to remember that it’s both a UNESCO World Heritage Site and a place of residence for many families
Don’t enter or photograph private homes or peek inside
Remember: Only designated buildings like museums
guesthouses and cafes are open to the public.
as littering can have a significant impact on the village’s rural environment
Be mindful of any wildlife you may encounter
The Ogimachi area of Shirakawa-go is small enough to get around on foot
Ogimachi is also the most convenient location for catching buses
The Shirakawa-go bus terminal is located at the entrance to Ogimachi and is serviced by buses destined for Takayama
Take the Hokuriku Shinkansen to Toyama Station
it’s approximately one and a half hours to Shirakawa-go by bus.
From the Meitetsu Bus Center (roughly 15 minutes on foot from JR Nagoya Station)
The trip takes approximately three hours.
Check Shirakawa-go’s official website for a comprehensive list of transportation options.
Shirakawa assessed her position in the AEW women's division heading into 2025
and what she hopes to bring to women's wrestling in North America
and I feel — I truly believe Japanese joshi wrestling skill is so good
so it's my mission to show our skill to AEW fans
It's my dream." Shirakawa also mentioned that she believes the AEW women's division is filled with strong
citing the likes of Kris Statlander and Hikaru Shida as dream opponents for the future

"Since you'll be here for Collision
Why don't you feel the wrath of Harley Cameron," Cameron said
Rack 'em up and may the breast woman win."
It's hard to turn down a challenge like that one and Shirakawa accepted it by shaking her boobs and saying
"I'll see you on Saturday."
an old-fashioned "boob shake off" between the wrestlers was underway
Paquette eventually stepped in to calm the situation down before one of the ladies accidentally suffered a wardrobe malfunction
That's how you promote the addition of a last-minute match. The episode of AEW Collision set to air on Saturday, is actually being taped tonight, reports Cageside Seats, at the MVP Arena in Albany, New York.
The Shirakawa and Cameron match is taking place on a lineup of matches that includes Daniel Garcia taking on Johnny TV, a tag team match between The Acclaimed and LFI with the winner advancing to the AEW world tag title match at Full Gear, and a women's world title match between Mariah May and Anna Jay.
I'm going to go out on a limb here and say that none of those matches had anything close to the promotion of Shirakawa and Cameron's. Not that they needed to.
The "boob shake off" that these two executed could carry the promotion for the entire event. Best of luck to all involved.

28 (Xinhua) -- Nestled in Japan's Ono District of Gifu Prefecture
Shirakawa-go is surrounded by towering mountains
The place is often blanketed by heavy snowfall in winter
too substantial to cause frequent traffic interruptions
earning Shirakawa-go the poetic titles of "a hidden gem" and "an isolated island."
the thickness of snow in Shirakawa-go often exceeds one meter
The harsh climate has shaped the unique architectural style known as "Gassho-zukuri," characterized by its steeply pitched
thatched roofs resembling hands pressed together in prayer
constructed entirely of wood and straw without the use of nails
are designed at a sharp 60-degree angle to facilitate the sliding off of snow
The beams of the houses are oriented east to west
ensuring ample sunlight and reducing wind resistance-ingenious adaptations born from villagers' long-standing experience of living in a cold
The traditional Gassho-zukuri houses require periodic replacement of their thatched roofs
a labor-intensive task that calls for collective efforts of the entire village
This cooperative practice is locally referred to as "Yui." In Japanese it means mutual assistance or share labor
People value the heart of Yui in Shirakawa-go
Life here has always been sustained through mutual aid and solidarity among families
when the place is cut off from the outside world by heavy snow
harsh natural conditions compel villagers to rely on one another for survival
has forged a unique bond of mutual support
Shirakawa-go together with Gokayama (In Toyama Prefecture) was registered as a UNESCO World Heritage Site (Cultural Heritage).Renowned for its distinctive architecture
Shirakawa-go has since become a highly sought-after tourist destination in Japan
visitors to the open-air museum in Shirakawa-go can immerse themselves in the traditional culture of the Gassho-zukuri village
The museum features 25 traditional Gassho-zukuri houses
Guests can closely observe the architectural nuances of the Gassho-zukuri roofs
and savor a bowl of traditional mochi red bean soup
To protect the villagers' living environment and preserve the natural and architectural heritage
Shirakawa-go has implemented various measures
residents have voluntarily established three principles of no selling
no renting and no destruction for their traditional houses
They also have decided against arbitrary renovations or alterations to the exteriors of private homes
the number of visitors and their hours of activity are strictly regulated
Day-trippers must depart by 5 PM to avoid disrupting the villagers' daily routines
and access to the scenic viewpoints is only permitted via shuttle buses within the village
These measures safeguard the precious traditional cottages
and exemplify the harmonious coexistence of culture and nature in modern society
Shirakawa-go is a blend of modernity and tradition
visitors from around the globe flock to this enchanting village
drawn by its unique culture and eager to explore its ancient charm
amidst the ever-changing world and the influx of new influences
Shirakawa-go remains steadfast in its commitment to preserving its timeless traditions and serene way of life

Maika will take place at Stardom’s April 2 show at Korakuen Hall
The lineup for her final match in Japan on April 6 will be announced at a later date
No matches have been announced yet for Stardom American Dream 2025
and fans for supporting her during her time in the promotion
She said she hopes to reunite with Stardom somewhere down the line and show fans an improved version of herself
The full press conference is available below
Mariah May won the AEW Women’s title back in August at All In
but she put off celebrating her win until she could toast her success with her friend
partner and the love of her life — Mina Shirakawa
The Japanese bombshell has been back in the States for a couple weeks
and the promotion was having their Full Gear PPV in Newark
Let the celebration BEGIN!Order #AEWFullGear on PPV right now!https://t.co/JlBXZPLNGj@MinaShirakawa | @MariahMayx pic.twitter.com/NUwWNb9lnE
It was also time for May to try and take out a potential rival
because she turned before the champ could smash a glass into her head
she speared The Glamour off the stage and through a table
Friends NO MORE!Order #AEWFullGear on PPV right now!https://t.co/JlBXZPLNGj@MinaShirakawa | @MariahMayx pic.twitter.com/pKGOBYi0Ku
That left Mina bleeding from the mouth (and possibly missing a tooth)
It made for quite a visual when she kissed the champ — her now former lover — on the forehead

It wasn't Toni Storm coming out of “retirement”, but let us know if you think a feud with Shirakawa will liven up May’s AEW Women’s World title reign. Then get complete Full Gear results and coverage of the entire show here
while also opening up about another reason why she loves Mina so much
"I remember meeting her a few years back when she was in her early 30s
she was new to our craft and shared her great passion for wrestling with me and wanting to wrestle in the U.S.
She honestly seemed to feel like it was too late for her
I do remember assuring her nothing could be further from the truth
and your children: it's never too late for any of us
And you heard it here from the CEO: you have not seen the last of this girl
and I couldn't be prouder to know her and to have competed against her."
After their match, Mone did attempt to shake Shirakawa's hand, but the challenger ultimately refused out of frustration due to losing. With that in mind, it's safe to say "The CEO" has not seen the last of Shirakawa
as Mone looks to have a very busy 2025 as a champion in three different companies
and the love of her life," bringing May out on to the stage
May said that it's been a "tough four months," but it was the celebration she always desired
and there's not a single woman in the division that can touch her
She then acknowledged Shirakawa as her "one true friend" who she couldn't have done anything without
but May grabbed the champagne bottle while Shirakawa's back was turned and looked to hit her with it
Shirakawa speared May off the stage and they went crashing through some tables below
screaming and crying before security rushed her off.
