Peptide signaling in anther development and pollen-stigma interactions

Abstract

Polypeptides play irreplaceable roles in cell-cell communication by binding to receptor-like kinases. Various types of peptide-receptor-like kinase-mediated signaling have been identified in anther development and male-female interactions in flowering plants. Here, we provide a comprehensive summary of the biological functions and signaling pathways of peptides and receptors involved in anther development, self-incompatibility, pollen tube growth and pollen tube guidance.

Keywords: Peptide; Pollen-stigma interaction; Receptor-like kinase; Tapetum.
