Deleting an xylosidase-encoding gene VdxyL3 increases growth and pathogenicity of Verticillium dahlia.

ABSTRACT:

Introduction

Verticillium dahliae causes a devastating Verticillium wilt disease on hundreds of plant species worldwide, including cotton. Understanding the interaction mechanism between V. dahliae and its hosts is the prerequisite for developing effective strategies for disease prevention.

Methods

Here, based on the previous observation of an xylosidase-encoding gene (VdxyL3) in V. dahliae being obviously up-regulated after sensing root exudates from a cotton variety susceptible to this pathogen, we investigated the function of VdxyL3 in the growth and pathogenesis of V. dahliae by generating its deletion-mutant strains (ΔVdxyL3).

Results

Deleting VdxyL3 led to increased colony expansion rate, conidial productio
