Abstract

Highlights: Bacterial blight and Fusarium wilt of cotton are recurrent diseases in U.S. cotton. SWEET sugar transporters function as a susceptibility factor of bacterial blight. Cell surface and intracellular immune receptors mediate host Fusarium wilt response. Environment–pathogen–cotton interactions underpin strategies for disease control. Abstract : Bacterial blight of cotton, caused by Xanthomonas citri subsp. malvacearum, and Fusarium wilt of cotton, caused by Fusarium oxysporum f. sp. vasinfectum, contribute cotton losses worldwide. Resurgences of these diseases in the United States were reported in recent years. There is a pressing need to understand pathogenicity and host responses to the pathogens and develop effective strategies for disease prevention and management. Here, we discuss the current status of bacterial blight and Fusarium wilt of cotton in the field as well as the knowledge of cotton resistance and susceptibility to these pathogens. In addition, we aim to provide insights into how these diseases are recurring and possible methods to use current technologies for biological control of these pathogens.
