The GLASSY HAIR3 pectate lyase family protein drives papillae formation on trichome cell walls.

Plant physiology - 1 Sept 2026

Rickerd Trevor, Fornero Christy, Dowell Gabrielle, Abdullah Abu Habib Md, Kirik Viktor

Abstract excerpt

Numerous papillae structures form on the cell wall surface of Arabidopsis trichomes. Papillae do not develop in the Arabidopsis glassy hair3 (glh3) mutant. Cloning of the GLH3 gene revealed that a member of the pectate lyase gene family is required for papillae formation. GLH3 pectate lyase expression is trichome-specific in leaves, and it precedes the appearance of papillae. The transcriptional Mediator complex...
