A timely paper for #MGM2024 next week. Congrats @firXLLi We show that HS inhibits sperm cell development and movement into pollen tubes impairing metaphase to anaphase transition during pollen mitosis II, deceasing yield @ThomasDresselh @USDA_NIFA @MaizeGDB
Heat stress at the bicellular stage inhibits sperm cell development and transport into pollen tubes

12 year after discovery, our work on pollen-specific RALFs in maize is finally published😅. We show that only Clade IB RALFs possess a dual role as cell wall component and extracellular sensors in regulating pollen cell wall integrity in maize. https://t.co/z4WeVbqn8t

In the F2 a few pink Arabidopsis roses popped up that were obviously homozygous for agamous, erecta, and the RUBY transgene. To my knowledge, this type of flower is the only one in the world and came just in time for Christmas ✨

At least 18 of the 37 RALF genes of Arabidopsis possess pollen (tube)-associated function. Now in print a report from the Qu lab how antagonistic RALFs mediate pollen penetration in stigmatic cells. A topic for the next journal club😊! https://t.co/U3WsDWZKS6

Good Scientific practice is a basic principle all young investigators should learn! Dr. Andrea Kliewer from the university of Jena told us about the DFG code of conduct and how it is influencing our daily work. Thanks for this fantastic workshop 👏😊!
