Por


ScienceDaily. Compared with culture medium-treated leaves (control treatment), fungal metabolites produced leaf lesions, decreased freephenolic contents and increased protein levels in both cultivars. In contrast, 67% to 100% of the control bananas were either dead or heavily TR4-infected after three years, including the Giant Cavendish somaclonal variant 218, currently … Soil degradation due to shortening fallow periods also accounts for decreased yields. cubense in China, Black Sigatoka leaf streaks of banana (Musa spp.) Fungal diseases of banana can be classed into diseases of the foliage, diseases of the root, corm and pseudostem and diseases of the fruit, including those at post harvest, such as anthracnose. A new variant, tropical race 4, threatens the trades that are now based on Cavendish cultivars, and other locally important types such as the plantains. Fusarium wilt is a fungal disease that leads the banana leaves to wilt and turns yellow around the margins. phenomenon of yield decline. News broke late last week that a fungal disease that kills Cavendish banana plants has been detected in Latin America for the first time. De très nombreux exemples de phrases traduites contenant "commercial banana production from a fungal disease" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. mL_1 of the biocontrol at planting and after removal of diseased plants, brought a control higher than 95% on plots of Burro CEMSA and FHIA 03 previously destroyed by the disease in conducible soils of commercial plantations. Such a procedure involved the in vitro treatment of fungal culture filtrates on to field-grown adult leaves and the measurement of lesion areas 48 h later. OECD Workshop - Sustainable Pest Management, Safe Utilization of New Organisms in Biological Control. ‘FHIA-01’ (resistant) leaves were treated with Fusarium oxysporum f. sp. In the 1950s, Fusarium wilt of banana, a fungal disease known also as Panama disease, wiped out large production areas of Gros Michel, the export banana variety at the time. Research on Musa at the International Institute of Tropical Agriculture (IITA) began in 1973. N.D.G. cubense. This was one of the findings discussed at the recent International Congress of Plant Pathology (ICPP) conference that took place in Boston from July 29 – August 3. The disease is particularly devastating because the fungus remains in the soil for decades. What Is This Banana Fungus? India is the leading producer of banana in the world and the present cultivation is vulnerable to this fungal disease which dwells in soil as a saprophyte and shifts to the parasitic mode in presence of host roots. Scientists are trying to understand the disease paradigm for developing innovative management strategies.

A prominent symptom exhibited by BSV is yellow streaking of the leaves, which becomes progressively necrotic producing a black streaked appearance in older leaves. New species and redispositions, Studies on Cercospora and allied genera. Current research at PBIP focusing on gaining insight into the Musa genome, developing Musa breeding capability, breeding for durable black sigatoka resistance, developing biotechnology techniques for Musa breeding, investigating the post-harvest quality of plantains and analyzing genotype-by-cropping system interactions. Fungal metabolites did not cause variations in peroxidase activity, chlorophyll pigment contents or malondialdehyde level in any cultivar. Panama disease Tropical Race 4—or TR4—is an infection of the banana plant by a fungus of the genus Fusarium. Researchers believe that the fungal disease is spreading slowly, but it will likely require genetic engineering or cross-pollination to create grocery store bananas that can survive the disease. Three other lines modified with RGA2 showed strong resistance, with 20% or fewer plants exhibiting disease symptoms over a period of three years. Sc. Jayas et R.N.

A fungal plant disease from Asia has been spreading across banana-growing areas of Latin America and the Caribbean since the 1960s. This is generally a result of freezing the fruit, and occurs most commonly in fruit that is sold in large stores or supermarkets. VII. A thesis submitted for the degree of Doctor of Philosophy of the Queensland University of Technology 2005 . The use of Fisher's linear discriminant analysis to differentiate resistant and susceptible banana cultivars in breeding programmes is also a novel aspect of this report.
