Abstract

The plasma membrane (PM) is a versatile and complex biological membrane, consisting of a dynamic assembly of lipids and proteins that protects the cell and separates it from its external environment. Lipids are essential in preserving the stability of the membrane while also regulating the activity of membrane proteins. Additionally, the PM significantly contributes to detecting environmental stress and serves as the primary target of its effects. These stressors induce modifications in the membrane composition, structure, and properties, which can ultimately disrupt cellular homeostasis. Ensuring the integrity and fluidity of the PM is vital for plants to survive harsh environmental conditions. The ability of plants to alter the composition of membrane lipids and proteins is vital for their adaptation to a range of abiotic stresses, such as extreme temperatures, drought, salinity, and heavy metal (HM) toxicity. Lipid remodelling influences the activity of membrane transporters which eventually governs the physical characteristics of the PM. To cope with harsh environment, plants rely on membrane transport systems working in tandem with the lipidome to uphold membrane stability. The review offers a comprehensive overview of the essential functions of PM proteins and lipids during stress, emphasizing the signalling pathways activated by the PM to counteract abiotic stress.

植物响应非生物胁迫的膜相关机制

质膜（PM）是一种多功能和复杂的生物膜，由脂质和蛋白质的动态组装组成，保护细胞并将其与外部环境分离。脂质在保持膜的稳定性方面是必不可少的，同时也调节膜蛋白的活性。此外，PM显著有助于检测环境压力，并作为其影响的主要目标。这些应激源诱导膜的组成、结构和性质发生改变，最终破坏细胞内稳态。确保PM的完整性和流动性对于植物在恶劣的环境条件下生存至关重要。植物改变膜脂和蛋白质组成的能力对于它们适应一系列非生物胁迫至关重要，如极端温度、干旱、盐度和重金属（HM）毒性。脂质重塑影响膜转运蛋白的活性，膜转运蛋白最终支配PM的物理特性。为了应对恶劣的环境，植物依靠膜运输系统与脂质组协同工作来维持膜的稳定性。这篇综述全面概述了应激过程中PM蛋白和脂质的基本功能，强调了PM激活的信号通路来对抗非生物应激。

期刊介绍： Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment. Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
