Yielding of plant-cell walls is defined by the mechanical properties of walls such as their extensibility ( Phi for in vivo, phi for in vitro cell wall) and yield threshold ( Y for in vivo, y for in vitro cell wall). A protein named yieldin, isolated from the cell wall of growing hypocotyls of Vigna unguiculata L. (cowpea), has been demonstrated to regulate the pH dependency of y in the cell wall of the glycerinated hollow cylinder of the cowpea hypocotyl. This mini-review outlines the process of the discovery of yieldin, and also refers to the progress of studies on yieldin: the molecular cloning of yieldin and its immunolocalization in the etiolated cowpea hypocotyl.
植物细胞壁的屈服性由细胞壁的力学特性定义,如细胞壁的伸展性(体内用Phi表示,体外细胞壁用phi表示)和屈服阈值(体内用Y表示,体外细胞壁用y表示)。从豇豆(Vigna unguiculata L.)生长的下胚轴细胞壁中分离出一种名为yieldin的蛋白质,它已被证明可调节豇豆下胚轴甘油化空心圆柱体细胞壁中y的pH依赖性。这篇小型综述概述了yieldin的发现过程,还提及了关于yieldin的研究进展:yieldin的分子克隆及其在黄化豇豆下胚轴中的免疫定位。
