Peptide Signaling in Pollen Tube Guidance

Curr Opin Plant Biol. 2015 Dec;28:127-36. doi: 10.1016/j.pbi.2015.10.006. Epub 2015 Nov 12.


Fertilization is an important life event for sexually reproductive plants. Part of this process involves precise regulation of a series of complicated cell-cell communications between male and female tissues. Through genetic and omics approaches, many genes and proteins involved in this process have been identified. Here we review our current understanding of signaling components during fertilization. We will especially focus on LURE peptides and related signaling events that are required for micropylar pollen tube guidance. We will also summarize signaling events required for termination of micropylar pollen tube guidance after fertilization.
