Fusarium oxysporum (Schlecht as emended by Snyder and Hansen), [1] an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking [2] within an infrageneric grouping called section Elegans.

Fusarium oxysporum stands out in several ways. It has an apparent long history of predominant, perhaps exclusive, asexual reproduction (Gordon and Martyn, 1997), it invades roots and can cause wilt diseases through colonization of xylem tissue (Tjamos and Beckman, 1989), and it displays apparent gene‐for‐gene relationships with several hosts.

Fusarium oxysporum f.sp. niveum (Fusarium wilt of watermelon); necrosis, with gummy exudate on a main vine of a watermelon plant. Note wilting of lateral vines and yellowing of leaves.

2019年3月4日 · We carried out a comprehensive search of the literature to propose this review of F. oxysporum formae speciales and races. We recorded 106 well-characterized formae speciales, together with 37 insufficiently documented ones, and …

Fusarium oxysporum f. sp. ciceris (Foc) is an ascomycete fungal pathogen that significantly limits chickpea productivity; causing annual yield losses of a 10 to 15%, and escalates to 100% when temperature and humidity are favourable. This review aims to assess the global scientific evidence on the distribution and pathogenicity, host responses ...

Fusarium diseases are significant hindrances to food plant production and are very difficult to control, especially soilborne diseases caused by F. oxysporum. First I outline the Fusarium diseases and introduce examples of the recent outbreak of Fusarium diseases in Japan.

2011年4月24日 · Fusarium oxysporum has many Formae speciales (special forms) that exist as plant pathogens, which are differentiated by host range, causing storage, root, stem, and fruit rot, as well as vascular wilt. They are also important mycotoxin (toxic metabolite) producers.

2024年10月20日 · Fusarium wilt, caused by the soilborne fungal pathogen Fusarium oxysporum f. sp. lactucae (FOL), is an economically important disease of lettuce (Lactuca sativa) throughout the world. Four pathogenic races of FOL are reported, though only …

Fusarium oxysporum is a common inhabitant of soil [1] and produces three types of asexual spores: macroconidia, microconidia and chlamydospores. [2]The macroconidia are nearly straight, slender and thin-walled. They usually have three or four septa, a foot-shaped basal cell and a curved and tapered apical cell. They are generally produced from phialides on conidiophores …

Fusarium oxysporum is the only Fusarium that actually grows inside the vessel system of the host plant and spreads upwards inside the plants. The other species are dispersed upwards on the outside of the plant. Most Fusarium species only make …
