Hybrid zones in Cardamine (Brassicaceae) reveal the formation of diverse triploid hybrids with evolutionary potential. Cardamine rivularis plays a key role as both a driver and a species at risk.

Excellent work from @piotraz.bsky.social group demonstrating juxtaposition of heterozygous & homozygous regions in maize attracts meiotic recombination to het regions rdcu.be/eHmn9 @natplants.nature.com builds from work we did together in Cambridge on Arabidopsis way back in 2015. Great stuff Piotr!

Enhancing local meiotic crossovers in Arabidopsis and maize through juxtaposition of heterozygous and homozygous regions

Nature Plants - This study discovered that locally confined DNA differences boost crossover rates in both Arabidopsis and maize, revealing a conserved mechanism that can accelerate plant breeding...

#Lobularia maritima (Brassicaceae) is often planted in strips next to vegetable fields in Brittany. It attracts pollinators and beneficial insects, helping to reduce pests and support healthy crops. 🐝🥬

Not #Boechera!
We used genomics, cytogenetics & phylogenetics to reveal that the mysterious Boechera calcarea is actually Parryodes calcarea - a rare Asian member of the Arabideae tribe (Brassicaceae):

So exciting to see Camelina sativa growing in Czech fields! Drought-tolerant, climate-smart, and a promising source of sustainable jet fuel.

Our analyses show that #Boechera calcarea doesn’t belong in Boechereae at all.
A rare case of deep taxonomic correction!

We decoded the genome of #Boechera falcata, the only Eurasian species in a mostly North American plant group. It helps us understand how it evolved and how it reproduces.

‼️Can we tune crossover hotspot activity by targeting chromatin modifiers? Absolutely!💥
Our screen shows dCas9-JMJ14 represses crossovers at targeted sites, while VP64 boosts them!
