📣 Our paper on ATR kinase in Arabidopsis meiosis is now online at @ThePlantCell ‼️ In _atr_ mutants, DSB levels remain stable, and crossover pathway choice is unaffected, but crossovers shift from pericentromeres to chromosome arms 😎

📣New research from our and @MonicaPradillo ‘s labs shows what happens when MLH1/3 complexes are lost in Arabidopsis! 🤩 Lots of unexpected findings! Special thanks to @NadiaKbiri ‼️

Our new paper compares meiosis in natural and neo allopolyploid Arabidopsis suecica. Homoeologous crossovers are 20-fold more frequent in first generation polyploids and show a strong bias toward chromosome ends. #meiosis #polyploid @CNibau @ibers_aber https://t.co/qB9ZbhtPlE

The Plant Meiosis Meeting is over‼️ We had over 100 participants from 17 countries worldwide🤠 Three days of amazing science🧬, networking, socializing🍾, and much more! It was an exceptionally stimulating experience on so many levels🤩 #plantmeiosismeeting #pmm #Plantmeiosis

[Piotr Ziolkowski @Piotraz1]

What a day…🤩

[Maja Szymanska-Lejman @SzymanskaLejman]

I am extremely happy to share that I was awarded the Sonatina grant to explore the meiotic recombination in pericentromeres 🥳 🥳 The project is soooo exciting that it deserved to be the FIRST on the ranking list!

[Piotr Ziolkowski @Piotraz1]

Today we went to Rogalin for our lab retreat🤩 It's so nice to spend some time with the whole group, having a lot of fun together while visiting the palace, the picture gallery and having walks in the palace gardens 🤠

[Piotr Ziolkowski @Piotraz1]

We have launched the #PLANTmeiosis homepage🥳

[Nadia Kbiri @NadiaKbiri]

Today I defended my doctoral research on the genetic regulation of meiotic crossover recombination. Cheers to a very wonderful journey and thank you to my PI, @Piotraz1, my amazing team, Ziołkowski Lab, and my jury, @Kyuha_C, B. Llorente and S. Swiezewski 🥳🎉

[Mónica Pradillo @MonicaPradillo]

Very happy to see this story finished, the fruit of a lot of hard work !!! https://t.co/QqjUotxs2Q

[Piotr Ziolkowski @Piotraz1]

MSH2 stimulates interfering and inhibits non-interfering crossovers in response to genetic polymorphism - now our paper is finally out in @NatureComms 🎉🎉🎉‼️
