【摘要】 细胞凋亡是生物体生长发育、细胞分化和病理条件下细胞主动、有序的死亡过程． 大量研究表明， 细胞凋亡是植物胚胎发育， 导管分子的形成， 根、茎、叶、花等器官正常生长发育的重要组成部分． 在植物的超敏反应中， 寄主细胞凋亡对限制病原物的扩散、保护植物整体发挥着重要作用更多还原

【Abstract】 Apoptosis is an active programmed cell death process during the organism development, cell differentiation and pathological situation. Many studies have revealed that apoptosis is an important and normal part in plant embryo development, tracheary element formation and development of root, shoot, leaf, flower. In hypersensitive response, plants use apoptosis in response to infection by pathogens to protect the whole plant survival.更多还原
