AI Summary

The study reveals that REMORIN protein evolution is primarily driven by diversification of their conserved C-terminal domain, defining four major clades. Structural bioinformatics predicts a common membrane‑binding interface with diverse curvatures and lengths, and suggests that some REMs can form C‑terminal‑mediated oligomers, adding complexity to membrane organization.

AI Summary

The study generated deep proteome and phosphoproteome datasets from guard cell‑enriched tissue to examine how phosphorylation regulates stomatal movements. Comparative analysis revealed increased phosphorylation of endomembrane trafficking and vacuolar proteins in closed stomata, supporting a role for phospho‑regulated trafficking in stomatal dynamics.

Model Organism: General

AI Summary

The study identified twenty survival of SA-induced death (ssd) mutants that are defective in starch, glucose, nitrate metabolism, and circadian regulation, leading to excessive carbohydrate accumulation and susceptibility to salicylic acid (SA)-induced death in prolonged darkness. Glucose application rescues SA‑treated plants by antagonizing oxidative stress and restoring metabolic balance, as revealed by transcriptomic analyses that link SA‑induced cell death to effector‑triggered immunity pathways.
