Phosphoinositides and Plant Cell Wall Synthesis
Phosphoinositides are lipid second messengers known to be important for many cellular processes in yeast, including actin cytoskeletal organization, vesicle transport, and cell wall assembly. In plant cells, studies on phosphoinositide phosphatases and kinases suggest that phosphoinositides are involved in the regulation of actin cytoskeletal organization, cell wall synthesis, and cell morphogenesis. It is hypothesized that phosphoinositides may regulate the transport of vesicles carrying cell wall biosynthetic enzymes and wall components, thereby influencing cell wall synthesis and cell morphogenesis.
