To respond to environmental changes, plants have developed complex mechanisms that allow them to rapidly perceive and respond to abiotic stresses. Late embryogenesis abundant (LEA) proteins are a large and diverse family that play important roles in environmental stress tolerance in plants. Dehydrins belong to group II LEA proteins, which are considered stress proteins involved in the formation of plants' protective reactions to dehydration. Some studies have demonstrated that dehydrins could binding metal ions or lipid vesicles. experiments revealed that dehydrins could protect the activity of enzyme from damage caused by environmental stress. Although many studies have been conducted to understand their roles in abiotic stresses, the molecular function of dehydrins is still unclear. In this review, to generate new ideas for elucidating dehydrins' functions, we highlight the functional characteristics of dehydrins to understand their roles under environmental stress in plants.
为了应对环境变化,植物已经形成了复杂的机制,使它们能够快速感知并响应非生物胁迫。晚期胚胎发生丰富(LEA)蛋白是一个庞大且多样的家族,在植物的环境胁迫耐受性中发挥着重要作用。脱水素属于II组LEA蛋白,被认为是参与植物对脱水形成保护反应的胁迫蛋白。一些研究表明,脱水素可以结合金属离子或脂质囊泡。实验表明,脱水素可以保护酶的活性免受环境胁迫造成的损害。尽管已经进行了许多研究来了解它们在非生物胁迫中的作用,但脱水素的分子功能仍然不清楚。在这篇综述中,为了产生阐明脱水素功能的新想法,我们强调脱水素的功能特征,以了解它们在植物环境胁迫下的作用。
