Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. In 2013, Fusarium community voiced near unanimous support for concept of represented clade comprising all agriculturally clinically important species, including F. solani species complex (FSSC). Subsequently, this was challenged in 2015 one research group who proposed dividing genus into seven genera, FSSC described as members...
Fusarium oxysporum formae specialis cubense (Foc) is a soil-borne fungus that causes wilt, which considered to be the most destructive disease of bananas. The believed have evolved with its host in Indo-Malayan region, and from there it was spread other banana-growing areas infected planting material. diversity distribution Foc Asia investigated. A total 594 F. isolates collected ten Asian countries were identified by vegetative compatibility groups (VCGs) analysis. To simplify...

From February April 2024, symptoms, typical Cn infection, were observed on (Zea mays L.) the North-West, Mpumalanga...
Fusarium oxysporum f. sp. cubense (Foc) causes wilt, a lethal disease that results in devastating economic losses to banana production worldwide. The pathogen originates from Asia where it evolved with its host, the wild plant Musa acuminata. Foc consists of three races, eight lineages and 24 Vegetative Compatibility Groups (VCGs). Most damage is caused by tropical race 4 (TR4), which occurs exclusively Asia. China biggest producer Cavendish bananas (AAA) world, plantations covering...
Fusarium oxysporum f. sp. cubense (Foc) is one of the most important threats to global banana production. Strategies control pathogen are lacking, with plant resistance offering only long-term solution, if sources available. Prevention introduction Foc into disease-free areas thus remains a key strategy continue sustainable In recent years, strains affecting Cavendish bananas have destroyed plantations in number countries Asia and Middle East, African country. One vegetative compatibility...
Fusarium wilt, caused by the soil-borne fungus oxysporum f. sp. cubense (Foc), poses a major threat to banana production globally. A variant of Foc that originated in Southeast Asia, called tropical race 4 (TR4), was detected on Cavendish export plantation (Metocheria) northern Mozambique 2013. TR4 rapidly disseminated farm, and affected approximately half million plants within 3 years. The also second commercial property 200 km away (Lurio farm) year later, small-grower’s near Metocheria...
Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) causes wilt of banana, the most devastating disease on a banana plant. The genome Foc TR4 encodes many candidate effector proteins. However, little is known about functions these proteins their contributions to development and virulence. Here, we discovered secreted metalloprotease, FocM35_1, which an essential virulence TR4. FocM35_1 was highly upregulated during early stages infection progress in bananas. knockout mutant...
