Characterisation of Arabidopsis ABA receptors

高等植物是一种无根生物，它们进化出了适应环境挑战的高度可塑性。病原菌和干旱、盐胁迫等非生物胁迫严重影响植物的生产性能和生产力。植物激素脱落酸（ABA）在生物和非生物胁迫反应中作为内源性信使。此外，在非胁迫条件下，ABA是调节生长发育的必需物质。最近对ABA受体的鉴定和大量不同ABA受体组合的出现，促使人们提出对ABA受体复合物及其与已知靶蛋白相互作用的详细分析。此外，本文还提出了调控ABA受体活性的分子机制以及ABA受体复合物的三维结构分析。

Higher plants are sessile organisms that have evolved a high plasticity for adaptation to environmental challenges. Pathogens and abiotic stress such as drought and salt stress severely impact plant performance and productivity. The phytohormone abscisic acid (ABA) serves as an endogenous messenger in biotic and abiotic stress responses. In addition, ABA is required to fine-tune growth and development under non-stress conditions. The recent identification of ABA receptors and the emerging combinatorial assembly of a multitude of different ABA receptors provide the incentive to propose the detailed analysis of ABA receptor complexes and their interaction with known target proteins. In addition, the elucidation of the molecular mechanism regulating ABA receptor activity as well as the three-dimensional structural analysis of an ABA-receptor complex is proposed.
