FERONIA调控质膜纳米簇以增强植物耐热性

FERONIA orchestrates plasma membrane nanoclusters for plant thermotolerance Kun Wang1,2, Hanqi Yan3, Xin Guo1, Qihong Lin1, Jing Li1, Aoyang Peng1, Ying Fu1, Zhizhong Gong1,4, Shuhua Yang1,2*, Yanglin Ding1* Climate warming poses increasing thermal challenges to plants, yet how plasma membrane biophysics contributes to heat adaptation remains poorly understood. In this work, we showed that the malectin-like receptor kinase FERONIa (FER) acts as a membrane- anchored thermal switch in Arabidopsis. FER organizes sterol- dependent nanoclusters that control heat acclimation. Moderate heat activated FER through the RaPID aLKaLINIZaTION FaCTOR 34 (RaLF34) peptide and promoted its recruitment to sterol- rich nanodomains. There, FER nucleated dynamic nanoclusters enriched in stress- signaling components. …
