Water availability positions auxin response maxima to determine plant regeneration fates - Nature Plants
This study reveals that water availability at the wound determines plant regeneration outcomes. High water availability induces root regeneration whereas low water availability triggers callus formati...

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social @erc.europa.eu 1/x 🧵 www.nature.com/articles/s41...
Plants monitor the integrity of their barrier by sensing gas diffusion - Nature
A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

Today in Nature we report a systematic strategy to activate & identify gene sets in plants. We identify 8 new genes from the yew tree's Taxol biosynthetic pathway, enabling us to engineer tobacco with 17- & 20-gene pathways to Taxol precursors baccatin III & deBz-deoxy-Taxol #SingleCell #secmet 🧬🧪🌾
Discovery of FoTO1 and Taxol genes enables biosynthesis of baccatin III - Nature
An approach that combines single-nucleus RNA sequencing and multiplexed perturbation identifies genes that enable the biosynthesis of direct precursors of the anti-cancer drug Taxol, whose curren...

SDG8 and HUB2 depositing euchromatin histone marks play important roles in meiosis and crossing‐over regulation
While meiotic crossing-over (CO) occurs in euchromatin, functional roles of active histone marks such as H3K36me3 and H2Bub1 in plant CO formation/frequency remain to be determined. We found that the...
