In-Silico Identification of Novel Resistant Genes for Fungal Pathogen Fusarium oxysporum f. sp. cubense Race 4: Causative Agent of Banana Vascular Wilt Disease .

Fusarium wilt of banana (Panama infection), brought about by the soil borne Fusarium oxysporum f. sp. cubense (Foc), is a common disease in the banana (Musa spp.) generation inclusively. Foc can affect the several types of Musa and Heliconia, their strains have been arranged into four physiological races. Race1 is pathogenic to ‘Gros Michel’(aaa) and “Silk” (AAB); Race 2 justinfluences the crossbreed triploid Bluggoe (ABB), and the race 4 attacks Cavendish cultivars, and all the cultivars susceptible to races 1 and 2, viewed as the most vital on the fact that it influences the cultivars which deliver more than 80% of the world’s bananas. The race 4 segregates are subdivided into subtropical race 4 (St4) and tropical race 4 (Tr4). The St4 segregate causes disease in Cavendish bananas in the subtropics, and Tr4 isolates are pathogenic both under tropical and subtropical conditions. 

In South China, Fusarium wilt of Xiang Jiao (AAA, Cavendish bananas) was initially reported in Guangdong Province in 2001, which brought about by Tr4. Till date, there are fewer fungicides accessible to control Fusarium wilt of banana. Chemical control is troublesome in light of the fact, that the chlamydospores can make holes in the soil. The best alternative is planting resistant cultivars, for example, Fusarium wilt-resistant bananas chose by means of genetic variations from tissue, and transgenic bananas. Notwithstanding, Fusarium wilt of banana is still a significant danger to banana production around the world. Quarantine policies and Foc free tissue culture planting materials are the vital methodologies to counteract the spread of infection.(Read more)
