FERONIA orchestrates plasma membrane nanoclusters for plant thermotolerance 

背景介绍

在全球气候持续变暖的背景下,高温胁迫日益成为威胁作物产量与粮食安全的关键因素。植物无法像动物那样通过行为调节体温,只能依赖内源机制来感知环境温度的变化并做出相应响应。细胞膜作为感知环境变化的先锋界面,在温和高温和热胁迫条件下其膜脂组成、膜流动性及局部物理性质均会发生动态重塑,使其成为植物最早解读温度信号的核心位点,然而这一过程的分子机制长期以来仍不明确。

文章概述

该研究首先通过磷酸化蛋白质组学分析发现在 37°C 处理下,拟南芥中的受体激酶 FERONIA(FER)的 Ser525 位点发生快速磷酸化并激活,且 FER 突变体表现出热敏感表型,从而证实 FER 是热响应所需的关键组分。进一步研究表明,中度高温(37°C)诱导 RALF34 肽配体成熟释放并激活 FER;同时,温度以不依赖FER的方式促使质膜甾醇转化为糖基化甾醇。激活的FER通过其近膜结构域中的碱性残基结合阴离子脂质(尤其是糖基化甾醇),被招募至甾醇富集的质膜纳米域中,迅速组装成信号纳米簇。这些纳米簇可招募下游信号组分(如 UGT80A2、REM1.3、BSK3),稳定液态有序膜相,激活 HSF-HSP 通路,增强获得性耐热性。当温度超过 40°C 时,F-actin 解聚导致 FER 纳米簇解体,以终止过度应激信号。在 28°C 温暖条件下,FER虽参与下胚轴伸长,但不发生磷酸化激活与纳米簇组装,这依赖于 phyB 介导的不同路径。综上,FER 通过形成与甾醇相关的动态纳米簇,实现对不同温度信号的解码与区隔。

该研究揭示了植物通过细胞膜纳米结构实现温度感知与耐热调控的关键机制,为通过定向优化膜脂组成、调控 FER 纳米簇组装及其相关支架因子以延长热保护窗口提供了清晰路径。这不仅为耐热作物的精准改良设计奠定了重要理论基础,也为培育适应气候变化的作物新品种提供了新的研究范式。
