Embryogenesis in plants is a unique process in the sense that it can be initiated from a wide range of cells other than the zygote. Upon stress, microspores or young pollen grains can be switched from their normal pollen development towards an embryogenic pathway, a pro...
aFor example, oligosaccharides such as galactinol and raffinose, which often accumulate to high concentrations, can also act as antioxidants and function as osmoprotectants in plant cells. 例如,低聚糖例如galactinol和棉子糖,经常积累到高浓度,在植物细胞可能也作为抗氧剂和功能作为osmoprotectants。[translate...
