Comparative Analysis Of Infection Process In Cotton Differing In Resistance To Fusarium Wilt Caused By Fusarium Oxysporum F. Sp. Vasinfectum Race 4

Fusarium wilt (FW), caused by the soil-borne pathogen Fusarium oxysporum f. sp. vasinfectum (FOV), is one of the most destructive diseases in cotton. FOV race 4 (FOV4) can cause serious yield losses and is an important threat to cotton production in the US. Understanding the infection mechanism of FOV4 is of importance for controlling the disease. In this study, roots of two cotton cultivars with different responses to FOV4 were compared under a scanning and a confocal micrpscope after inoculations with a highly virulent FOV4 isolate.
