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.

高等植物是无柄生物，为了适应环境挑战而进化出了高可塑性。病原体和非生物胁迫（例如干旱和盐胁迫）严重影响植物的性能和生产力。植物激素脱落酸 (ABA) 在生物和非生物应激反应中充当内源性信使。此外，ABA 需要在非应激条件下微调生长和发育。最近对 ABA 受体的鉴定以及多种不同 ABA 受体的新兴组合组装为提出对 ABA 受体复合物及其与已知靶蛋白相互作用的详细分析提供了动力。此外，还提出了阐明ABA受体活性调节的分子机制以及ABA-受体复合物的三维结构分析。
