''Fusarium oxysporum f.sp. ciceris'' is a fungal plant pathogen that causes fusarium wilt of chickpea. ==Description== ''Fusarium oxysporum'' is a common soil inhabitant and produces three types of asexual spores; macroconidia, microconidia and chlamydospores.〔(PaDIL )〕 The macroconidia are straight to slightly curved, slender, thin walled usually with three or four septa, a foot-shaped basal cell and a tapered and curved apical cell. They are generally produced from phialides on conidiophores by basipetal division. They are important in secondary infection.〔Couteaudier, Y. and C. Alabouvette, 1990 Survival and inoculum potential of conidia and chlamydospores of Fusarium oxysporum f. sp. lini in soil. Can. J. Microbiol. 36:551-556〕 The microconidia are ellipsoidal and either have no septum or a single one. They are formed from phialides in false heads by basipetal division. They are important in secondary infection.〔 The chlamydospores are globose and have thick walls. They are formed from hyphae or alternatively by the modification of hyphal cells. They are important as endurance organs in soils where they act as inocula in primary infection.〔 The teleomorph or sexual reproductive stage, of ''F. oxysporum'' is unknown.〔Leslie JF, Summerell BA (2006) The Fusarium Laboratory manual.
