Characterisation of Arabidopsis ABA receptors

高等植物是固着生物，已进化出高度可塑性，以适应环境挑战。病原菌和非生物胁迫，如干旱和盐胁迫，严重影响植物的表现和生产力。植物激素脱落酸(ABA)是生物和非生物胁迫反应的内源信使。此外，ABA还需要在非胁迫条件下微调生长发育。最近对ABA受体的鉴定和大量不同的ABA受体的组合组装的出现，促使人们提出对ABA受体复合体及其与已知靶蛋白的相互作用进行详细分析。此外，还提出了调控ABA受体活性的分子机制以及ABA-受体复合体的三维结构分析。

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.
