高等植物对环境干扰和非生物胁迫的反应是迅速重塑细胞脂质。植物中的脂质具有许多重要功能，包括信息交换，保护，能量储存，信号和光捕获。不饱和度的增加是对冷应激的常见反应，但不是适应的唯一机制。增加对脂质周转的理解对于确定脂质组对植物抗逆性的贡献至关重要。存在通过操纵脂质组来提高作物的适应性的机会。环境制约因素限制了许多重要经济作物的地理分布。低温胁迫是一种重要的非生物胁迫，它影响植物的生长发育，导致植物活力丧失和表面损伤。这些症状是由细胞膜的物理和化学成分改变引起的。作为细胞膜的主要成分，脂质已被认为在冷胁迫中具有重要作用，既作为通过叶片表面保护和质膜重塑的机械防御，又作为信号转导分子。我们提出了一个概述，整合基因表达和脂质组学数据发表到目前为止，在拟南芥及其近的极端嗜盐植物盐地黄葵。该数据使得能够更好地理解脂质组在确定耐受次优温度条件的能力方面的贡献。总的来说，这些信息将使我们能够确定负责恢复力的关键脂质和途径，从而能够开发作物耐受压力的新方法。
Higher plants rapidly remodel cellular lipids in response to environmental perturbation and abiotic stress. Lipids in plants perform many important functions including information exchange, protection, energy storage, signalling and light capture. Increases in unsaturation are a common response to cold stress, but not the only mechanism of adaptation. An increased understanding of lipid turnover is essential to establish the contribution made by the lipidome to plant stress resilience. Opportunities exist to improve the resilience of crops by manipulating the lipidome. Environmental constraints limit the geographic distribution of many economically important crops. Cold stress is an important abiotic stress that affects plant growth and development, resulting in loss of vigour and surface lesions. These symptoms are caused by, among other metabolic processes, the altered physical and chemical composition of cell membranes. As a major component of cell membranes lipids have been recognized as having a significant role in cold stress, both as a mechanical defence through leaf surface protection and plasma membrane remodelling, and as signal transduction molecules. We present an overview integrating gene expression and lipidomic data published so far in Arabidopsis and its relative the extremophile Eutrema salsugineum. This data enables a better understanding of the contribution of the lipidome in determining the ability to tolerate suboptimal temperature conditions. Collectively this information will allow us to identify the key lipids and pathways responsible for resilience, enabling the development of new approaches for crop tolerance to stress.
