Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...
Considering my book "The Tree of Life" for introductory evolution class? I have a few complimentary copies to evaluate. Please DM me. And please repost.
Review in Science described it as "..a fantastic informal introduction to a course on evolution.. recommended it to my first-year students".

Happy to share our latest work in collaboration with the lab of @pengbo10.bsky.social. Here, we describe that a formin protein mediates the polarity switch from root hair to infection thread growth during symbiotic interactions.

Congrats Alibek, Yasin et al
Something tells me I should go to the membrane contact sites session...
Sun 🔆 is rising over the bay of Eilat/Aqaba and the 2nd day of ILANIT 2026 is coming up.
We had a fab lab trip last week 🌻
Long in the making, but happy to present the Chlamydomonas chlororibosome!
Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins.
bioRxiv 📖: shorturl.at/q44tG
This suggests greater chlororibosome diversity than expected!

"The most uncomfortable part for me is that I no longer think that scientific research will resolve the crises that we face."
"I keep doing research not because I think it will save us, but because it would be a form of surrender to stop seeking understanding."
Beautiful #preprint on a novel regulator of plant #autophagy from the @cnaumann123.bsky.social lab. How do plants regulate #autophagosome size??? ER-PM contact sites and Can1 seem to be key! www.biorxiv.org/content/10.6...
Our own Dorothy Matiki presented her research (on autophagy in 🍅 ripening) impressively and earned her M.Sc. title! 🎉🍾
Soon Dorothy will meet the @weizmanninstitute.bsky.social Doctoral studies committee to (hopefully) approve her joining the lab of Prof. Michal Sharon.
All the best Dorothy!
In @science.org this week, thermospermine affects ribosome methylation, which in turn regulates translation of xylem development proteins www.science.org/doi/10.1126/...

Dear @dfg.de So, I will spend months writing a grant and you will let people judge it with AI tools that are trained on predatory journals like Frontiers, MDPI or alike that are practically not peer-reviewed??? Is this how you will select cutting edge science??? #idiocracy
Fig. 1 (shortened, full legend in paper): Complexity of gynoecium development shown with confocal microscopy imaging. (A) Meristematic stages of floral development in which the inflorescence meristem (IM) is observed; from stage 3, the sepal primordia (asterisks) are observed; in stage 4, the developing sepals (asterisks) partially cover the floral meristem (FM); and in stage 5, the FM is completely covered by the sepals. (B) Stage 6 in which the gynoecium is established with the appearance of the primordium of the gynoecium. (C) In stage 7, the middle and lateral domains can be differentiated (marked by dotted lines). (D–H) Longitudinal view of the gynoecium from stage 8 to 12. At stages 8 and 9, the gynoecium grows as a hollow tube and the valves and young replum can be seen. (F and G) Longitudinal view of stage 10 and 11 gynoecia showing the replum and valves. (H) Mature stage 12 gynoecium showing the stigma, style, and ovary, the latter formed by the valves and replum.

Why are so many plant viruses phloem-restricted? New work from Xueping Zhou’s lab reveals how this tissue tropism is determined in a geminivirus — and why phloem confinement can turn out to be an evolutionary advantage! www.nature.com/articles/s41... 🌱🦠🚷🅿️🛫🌱
Our work now on @jxbotany.bsky.social. Make sure you add some Cas13a fluorescent virus detection to your Christmas lights ✨️

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n
The Clavel Group is recruiting a new postdoc for two possible projects dealing with plant-virus interactions and selective autophagy! More (wordy) details below ⬇️🌱🦠
