Breakthrough in Maize Transformation! 🌽⚡ Schnittger’s Team at Univ. of Hamburg Reconstructs Tissue Culture in The Plant Journal (2026)!
Achieves up to 671.4% regeneration frequency without relying on BBM/WUS2 morphogenic regulators! 🎯📦
Key Technological Breakthroughs:
🛠️ 8 Core Optimization Steps: Optimized semi-submerged embryo co-cultivation, meropenem substitution, a 10-day resting phase, and repeated callus splitting.
🧪 Silwet L-77 Flash Pre-Treatment: Brief 0.0001% Silwet exposure boosts infection depth, yielding up to 671.4% regeneration (4.71-14.20 independent events / 100 embryos).
🔍 TAFLP Molecular Diagnostic: Developed T-DNA Amplified Fragment Length Polymorphism to distinguish true independent integration events from clonal regenerants.
✂️ High-Efficiency CRISPR/Cas9 Editing: Validated on meiotic genes MAC1 (>94% editing rates across BASTA/Hygro) and ACOZ1 (394 bp knockout), unlocking novel meiotic nuclear dynamics.
🌾 Genotype & Selection Flexibility: Successfully adapted to B104 with compatibility across BASTA, Hygromycin, and G418 selection markers.
A major milestone for streamlining crop transformation CRO workflows and functional genomics! 🚀🌟

Last night, Ukraine’s Defense Forces struck an airfield in the Voronezh region. Four Su-34 aircraft were destroyed and two more Su-34s were hit. The Russians used them to terrorize our people. These very warplanes were ready to launch new attacks on Ukraine and were loaded with aerial bombs.
Our Long Neptune missile was used to strike the target. I thank the warriors of the Ukrainian Navy for their precision!
Our long-range sanctions also reached a site in the Oryol region used to store and launch attack drones. A target was also hit in the Black Sea.
These are our justified responses to all of Russia’s terror against Ukraine. Russia is dragging out the war, so our long-range operations will continue.

Today, Peter and Ahel shared their expertise in advanced microscopy with colleagues during a hands-on spinning disk microscopy training! 🔬
Thanks for sharing your knowledge, tips & tricks, and showing us how to make some really cool root growth movies 🎬

Kyiv is in a blackout. No water either. Kharkiv’s thermal power plant is being bombed right now.
Energy ceasefire? What energy ceasefire?

Now also with a Nature Plants Research Briefing! 🌱
A short overview of how SNI1/NSE5 links temperature to meiotic crossover control in Arabidopsis.
New OA Article: "SNI1/NSE5 is a cold-sensitive brake on class II crossovers in Arabidopsis"

Barley comes in way more shades than you'd think! 🌾 We’re using the Oregon Wolfe Barley population, an amazing genetics teaching tool developed by the folks at OSU, to help bring plant biology to the public. It’s a perfect visual of the black lemma and pericarp locus (Blp1).

1/2 My very first post on X—and what better occasion than the publication of our paper in @NaturePlants! 🌱
We identify SNI1 as the first plant gene linking temperature to meiotic recombination, generating genetic diversity that may help plants adapt.

‼️A new story from our lab!🙌 We show that SNI1, a component of the SMC5/6 complex, acts as a temperature-dependent brake on class II crossovers, helping shape where genetic exchange occurs in Arabidopsis. Huge effort by Alex made it happen🙏

This week, Adam and Martin attended the “At the Forefront of Plant Research” conference at VIB in Ghent, presenting their work with beautiful posters. Martin also gave a talk at VIB’s Early Career Research Day. #ParentalConflict #Barley #Seed

New cat species discovered in over 100 years
Scientists have identified Leopardus tilcayo, a tiny wild cat found in Bolivia’s Yungas forests. The discovery began with a wildlife sanctuary reporting a “weird cat” and was later confirmed through genetic research

New cat alert! A call from a wildlife sanctuary about a "weird cat" has led to the first new cat species discovered in over 100 years in Bolivia’s Yungas forest ecoregion. Learn more about this feline surprise: on.natgeo.com/JRuaGj

A new genome resource for the barley community!
Use FluentDNA to explore genomic features such as gene clusters, telomeric repeats and GC rich regions, of the Bere Unst genome assembly. It's google maps for genomes!
