Complex sexual signals for the male gametophyte

Curr Opin Plant Biol. 1999 Oct;2(5):419-22. doi: 10.1016/s1369-5266(99)00015-1.


The pollen grain and the pollen tube that grows from it are complex entities which must respond to a diverse array of signals to carry out their roles in sexual reproduction. Research is beginning to reveal the nature both of the signals and of the signal transduction machinery that converts these signals into directional, polarized growth.
