Enhancing maize resistance to Fusarium verticillioides through modulation of cell wall structure and components by ZmXYXT2.

ABSTRACT:

Introduction

Fusarium verticillioides (F. verticillioides) is a prevalent phytopathogen that incites severe diseases in maize, resulting in substantial reductions in grain yield and quality. Despite its widespread impact, the genetic mechanisms underlying resistance to this pathogen remain elusive, with only a limited of resistant genes having been identified to date.

Objectives

Characterize the function of ZmXYXT2 encoding a putative xylan xylosyltransferase in maize defense against F. verticillioides-induced diseases.

Methods

Real-time quantitative PCR and transitory transformation of maize protoplasts were conducted to analyze the expression pattern and subcellular localization of ZmXYXT2. The zmxyxt2 mutant, sourced from an ethyl methanesulfonate mutagenesis libra
