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...

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.

🌱🧬 SPECIAL ISSUE REVIEW 🌱🧬

Tremblay & Qüesta discuss how examining the seed-to-seedling transition can reveal how non-coding RNAs and epigenetic changes regulate transcription during developmental transitions.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @jiquesta.bsky.social‬
Figure 2 (shortened, see paper for full legend): Long non-coding RNAs participate in both activation and repression of genes preventing germination. (A) Under red and far-red light conditions, phytochrome B (phyB) promotes accumulation of the HIDDEN TREASURE 1 (HID1) lncRNA in the radicle of germinating seeds to repress transcription of genes which slow germination. For the repressor PHYTOCHROME-INTERACTING FACTOR 3 (PIF3), HID1 RNA directly interacts with the chromatin in its promoter region, repressing transcription. For other genes such as the ABA biosynthesis gene 9-CIS-EPOXYCAROTENOID DIOXYGENASE (NCED9), HID1 not only interacts with the chromatin in its promoter region, but also with the histone methylase ARABIDOPSIS TRITHORAX-RELATED7 (ATXR7) to suppress its ability to deposit the activating gene body mark H3K4me3, thus reducing transcription of NCED9. (B) Transcription of the dormancy-promoting gene DELAY OF GERMINATION1 (DOG1) is induced and repressed by different lncRNAs.

Great collaboration with @yvonjaillais.bsky.social 🌱 Plants use membrane contact sites (MCS) for cell-to-cell signaling!
➡️ MCTP tethers & PI4P regulate ER-PM contacts in plasmodesmata, impacting trafficking.
➡️ MCS roles span intra- and intercellular communication.
