种子萌发是高等植物生命周期的又一个开始,其受到多种环境因子和植物激素的影响。其中最重要因素是赤霉素(Gibberellins,GAs)。当植物种子吸水后,胚开始合成GAs并释放到糊粉层细胞。糊粉层细胞接受到GAs信号后开始合成水解酶(如α-淀粉酶)并分泌到胚乳中水解淀粉为小分子糖,为种子萌发与幼苗生长提供能量。水稻抗病调控蛋白Os LOL1在水稻抗病中起到重要作用,但中国科学院 Seed germination is another beginning of the life cycle of higher plants, which is affected by a variety of environmental factors and plant hormones. The most important factor is Gibberellins (GAs). After the plant seeds have absorbed water, the embryos begin to synthesize GAs and are released into aleurone cells. The aleurone cells begin to synthesize hydrolases (such as α-amylase) after receiving GAs signals and are secreted into the endosperm to hydrolyze the starch to small molecule sugars to provide energy for seed germination and seedling growth. Rice disease-resistant regulatory protein Os LOL1 plays an important role in rice disease resistance, but Chinese Academy of Sciences
