Interpretive Summary: Verticillium dahliae is a soilborne fungus that causes disease known as Verticillium wilt on over 400 plant species worldwide, including many agriculturally important crops. Symptoms of Verticillium wilt disease include vascular tissue discoloration in stems, leaf wilting, and can result in the death of susceptible plant hosts. In some plant host types, such as in trees and cotton, infection with certain strains of Verticillium dahliae results in a symptom of leaf defoliation. The strains that cause the leaves to drop from the plant prematurely have historically been referred to as defoliating strains. Understanding the genetic basis for the more severe defoliation symptoms associated with the defoliating strains will help us to devise new treatment approaches to help combat Verticillium wilt diseases. This work provides the foundation to decipher the genetic differences between the defoliating and non-defoliating strains.

Technical Abstract: Verticillium dahliae is a widely distributed soilborne pathogen that causes vascular wilt in more than 400 plant species. Defoliating and non-defoliating phenotypes divide V. dahliae into two broad pathogenic groupings, dependent on whether the pathotype results in loss or retention of plant leaves, respectively, in several different hosts such as cotton, olive, and okra. Our goal in this current work was to generate genome resources for defoliating strain XJ592 and non-defoliating strain XJ511 of V. dahliae isolated from cotton in China.
