Abstract
Fusarium oxysporum is known to cause vascular wilt and root rot of many important plants. Although extensive studies have been reported for the model plant Arabidopsis thaliana (L.) Heynh., the question of whether those experimental interpretations are extendable to other crop species requires experimentation. Chickpea is the most important crop legume of Indian subcontinent and ranks third in the world list of important legumes. However, productivity of this crop is severely curtailed by vascular wilt caused by Fusarium oxysporum f. sp. ciceri. Based on earlier reports, the present review discusses about the external manifestations of the disease, in planta fungal progression and establishment, and the molecular responses of chickpea that occur during Fusarium oxysporum f. sp. ciceri Race 1(Foc1) interaction. Foc1, known to enter the roots through the breaches of tap root, colonise the xylem vessels and block upward translocation of essential solutes causing wilt in compatible hosts. In contrast, pathogen invasion is readily perceived by the resistant host, which activates defence signalling cascades that are directed towards protecting its primary metabolism from the harmful consequences of pathogenic mayhem. Hence, understanding the dynamic complexities of chickpea-Foc1 interplay is prerequisite to providing sustainable solutions in wilt management programs.
