Abstract: The phosphoinositide signal systems are based on inositol phospholipid metabolism and circulation and include 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.

Key words: inositol phosphate signaling, phospholipase C, pollen development, pollen tube growth
