Two days of retreat and amazing discussions with @cosheidelberg.bsky.social ; @igflyon.bsky.social ky.social & @rdplab.bsky.social The power of science really shows when different organisms (and minds!) come together.

Ahead of Clara Igisch’s PhD defense tomorrow, we enjoyed four excellent talks today in a 🌱 mini-symposium: @emmanuellebayer.bsky.social / @ottlab.bsky.social / @jennyrussinova.bsky.social & @structplantbio.bsky.social Great science, great stories!

New Article: "ATG5–HSP90.2-mediated micromitophagy as a cytological basis for maternal inheritance of plant mitochondria" rdcu.be/eZ87l Micromitophagy in male germline cells underpins paternal mitochondrial elimination and supports the zygote-to-embryo transition.

Save the date: Plant Development PhD school (i.e. Retzbach 2.0) in Neustadt, Germany. Sept 23rd-25th, 2026 ~€350 all inclusive Excellent speakers and a relaxed atmosphere for early-career researchers (PhDs & postdocs). Registration opens soon. For more info, see raissiglab.org/plantdevosch...

🧬🌽 RESEARCH 🧬🌽 A new whole-genome assembly of maize identifies a potential regulator of crossover frequency and other effects on expression of A-chromosome genes mediated by the B chromosome - Hloušková et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...
