蛋白质动力学如何促进发育过程是一个关键的生物学问题。在本期的《发育细胞》中,Ju等人表明,雌性配子体中NORTIA的亚细胞定位是花粉接收所必需的。NORTIA的再分配促进了花粉管破裂的信号,从而促进了雄性配子的释放和受精。
How protein dynamics contribute to developmental processes is a critical biological question. In this issue ofDevelopmental Cell, Ju et al. show that subcellular localization of NORTIA in the female gametophyte is required for pollen reception. NORTIA redistribution boosts cues that drive pollen tube bursting, thus promoting male gamete release and fertilization.
