Anisotropic diffuse growth in Arabidopsis thaliana stigma papillae.

Plant reproduction - 4 Jun 2025

Davis Thomas C, Kessler Sharon A

Abstract excerpt

KEY MESSAGE: Arabidopsis stigma papillae grow by a diffuse growth mechanism rather than by tip growth. In angiosperms, the stigma is the first point of contact between the pollen (male) and pistil (female) during pollination. The stigma facilitates pollen capture and adhesion, compatibility responses, pollen germination, and pollen tube guidance to the transmitting tract. In Arabidopsis thaliana, the stigma is...
