- “The ZAT14 family promotes cell death and regulates expansins to affect xylem formation and salt tolerance in Arabidopsis”. Now out in @theplantcell.bsky.social led by Ming Feng and colleagues. A 🌱 thread 👇 1/x academic.oup.com/plcell/advan...
- 2/ Using a grafting dataset (www.pnas.org/doi/10.1073/...), we identified a group of four closely related ZAT transcription factors expressed in the xylem, phloem and lateral root cap.
- 3/ Single mutants showed no phenotypes, but double, triple and quadruple mutants perturbed vascular patterns and cell death in root caps. The expression of ZAT14 family members in tissues undergoing cell death, or cell enucleation, suggested they might play a role in death priming.

- How do plants decide the fate of a wound and what to regenerate? Water availability! Abdul Kareem and colleagues show that regeneration outcomes after tissue cutting are controlled by water. A 🧵/n 👇 www.nature.com/articles/s41...
- 2/n. Regeneration is fundamental for plant survival but how do plants know what to regenerate? We sought to address this question using cut Arabidopsis petioles that can either form roots, callus or both at the site of wounding
- 3/n. Roots formed at wounds follow a lateral root formation pathway (pubmed.ncbi.nlm.nih.gov/24642937) but what about callus from wounds? We used reporters and mutants to find that callus follows a procambium pathway suggesting that different regeneration fates used different molecular pathways.

- Beautiful work showing opposing gradients of gases activates regeneration in wounded Arabidopsis roots. Congrats to all authors! Some interesting future questions raised regarding aerial tissues and non-Arabidopsis. How do they activate regeneration? Next big questions for the field.
- 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...

- Now out, our work describing a long-distance inhibitory system regulating haustoria numbers in parasitic plants. @biorxiv-plants.bsky.social A thread... www.biorxiv.org/content/10.1...
- 2/n. Parasitic plants form infective structures known as haustoria, and these can be positively or negatively regulated by hormones, peptides and external nutrients
- 3/n. We wondered whether parasitic plants have an endogenous system to control their haustoria numbers, similar to other auto-regulating symbioses, and found that existing haustoria repressed the formation of new haustoria in two parasitic plant species
