Unlocking a 'lock-key' mechanism governing pollen-pistil interactions

Trends Plant Sci. 2024 Apr;29(4):394-396. doi: 10.1016/j.tplants.2023.12.002. Epub 2023 Dec 16.

Abstract

Pollen-pistil interactions ensure genetic diversity and shape the reproductive success of plants. Lan et al. recently revealed that the interaction among various receptor-like kinases, cell-wall proteins, and stigmatic RALF peptides (sRALFs) or pollen RALF peptides (pRALFs) on the stigma surface govern the penetration of pollen tubes in members of the Brassicaceae.

Keywords: Arabidopsis thaliana; Brassicaceae; peptides; pollen–pistil interactions; receptors.
