Reposted by Steven ZwartkruisMaurice König @maukoe.bsky.social · 15/05/2026One highlight from our review: peptide signals can be copied or rerouted to redirect plant responses. 🌱 Bacteria, fungi and nematodes tap into phytocytokine pathways via mimics or altered release - steering infection, colonization and symbiosis. Read more about it here: doi.org/10.1111/tpj....doi.orgProcessing and release of endogenous immunogenic peptide signalsPlant endogenous peptides, termed phytocytokines, coordinate immune responses and mediate intercellular communication within and across plant tissues.

Reposted by Steven ZwartkruisLuis Alonso Baez @luisalonsobaez.bsky.social · 18/02/2026Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included. www.science.org/doi/10.1126/...science.orgThe mechanical properties of Arabidopsis thaliana roots adapt dynamically during development and to stressBrillouin microscopy reveals in vivo dynamics of mechanical properties during plant development and response to stress. 57037

It contains both DUF4409 and DUF239 domains. Loss of function mutations show defects in formation of the Casparian band, which is correlated with mis-localization of CASP1.
