【摘要】 肌醇磷脂信号系统以肌醇磷脂代谢循环为基础,由多种磷酸磷脂酰肌醇分子和多磷酸肌醇分子及催化代谢的磷脂酶、激酶组成。该信号系统参与调节动、植物细胞生长发育及应答环境刺激等多种生理过程。花粉发育和花粉管的生长是植物有性生殖的基础,肌醇磷脂信号系统中多种组分参与其生理过程的调节。该文综述了植物肌醇磷脂信号系统中各组分的相互关系,以及相关组分调节花粉发育和花粉管生长生理过程的研究进展。更多还原

【Abstract】 The phosphoinositide signal systems are based on inositol phospholipid metabolism and circulation and in- clude a variety of phosphatidylinositol phosphate molecules and phospholipases and kinases. The signaling molecules are involved in regulating the plant growth and the response to environment. Much research has used genetic and molecular approaches to confirm that the inositol phospholipids and their phospholipid turnover products participate in pollen development and pollen tube growth, which are important for plant growth. In this review, we summarize research progress in investigating signal molecules as regulators in pollen development and pollen tube growth.更多还原
