Abstract

In flowering plants, pollen tubes deliver and release the immotile sperms to the female gametes for fertilization, but mechanisms remain unclear. New results show that the RALF family peptides control pollen-tube integrity and burst by binding to CrRLK1L family receptors and cell wall leucine-rich repeat extensins.

Keywords: CrRLK1L; LRX; RALF; burst; pollen-tube integrity.
