| 摘 要： | 在合适的培养条件下,植物体细胞会模仿胚胎发育过程产生体细胞胚胎。体细胞胚胎发生提供一个实验系统,便于研究植物形态建成的分子和细胞机制等方面。文中主要对体细胞胚胎发生的影响因素(激素、胁迫因素和Ca2 等)和该过程中的基因表达与调控方面论述了国内外研究进展。

| Abstract: | Under appropriate in vivo or in vitro conditions,certain somatic plant cells have the capability to initiate embryogenic development(somatic embryogenesis).Somatic embryogenesis provide an unique experimental model to understand the molecular and cellular bases of developmental plasticity in plants. In this review,we summarize the role of endogenous growth regulation,stress and Ca2 and the regulation of gene expression during the somatic-to-embryogenic translation. |

| Keywords: | Somatic embryogenesis Endogenous growth regulation Stress factor Ca2 Gene expression |
