The LoMYB26/LoJAZ4-LoCOMT module regulates anther dehiscence via Jasmonic acid-mediated endothecium lignification in lily.

ABSTRACT:

Introduction

Timely anther dehiscence is a key step for successful sexual reproduction in plants. Secondary cell wall thickening of anther endothecium is a vital process during anther dehiscence that provides an indispensable mechanical force for successful dehiscence. Anther dehiscence depends on anther lignification, and it is a timely and sophisticated process regulated by phytohormones and transcription factors. However, whether endothecium lignification occurs during anther dehiscence in lily and underlying mechanisms are still largely unclear.

Objectives

Our work focuses on identifying the course of endothecium lignification during anther dehiscence and elucidating the molecular mechanisms underlying endothecium lignification-dependent anther dehiscence in lily.
