Controle E Condições Climáticas Favoráveis À Antracnose Do Mamoeiro
Control and favourable weather for anthracnose of papaya Anthracnose and stem-end rot (SER) are the main post harvest diseases of papaya (Carica papaya) in Brazil. The effectiveness of 11 treatments (mg.l-1 a.i.) on the their control was evaluated: 1chlorothalonil WP (1500); 2-chlorothalonil SC (2000); 3-chlorothalonil + copper oxychloride WP (875 + 1050); 4-thiofanate-metil + chlorothalonil WP...
متن کاملSize and complexity of the nuclear genome of Colletotrichum graminicola.
DNA reassociation was used to estimate GC content, size, and complexity of the nuclear genomes of Colletotrichum from maize and sorghum. Melting-temperature analysis indicated that the GC content of the maize pathotype DNA was 51% and that the GC content of the sorghum pathotype was 52%. DNA reassociation kinetics employing S1 nuclease digestion and an appropriately modified second-order equati...
متن کاملAntifungal metabolites (monorden, monocillins I, II, III) from Colletotrichum graminicola, a systemic vascular pathogen of maize.
Colletotrichum graminicola is a systemic vascular pathogen that causes anthracnose stalk rot and leaf blight of maize. In the course of an effort to explore the potential presence and roles of C. graminicola metabolites in maize, ethyl acetate extracts of solid substrate fermentations of several C. graminicola isolates from Michigan and Illinois were found to be active against Aspergillus flavu...
متن کاملRoot-expressed maize lipoxygenase 3 negatively regulates induced systemic resistance to Colletotrichum graminicola in shoots
We have previously reported that disruption of a maize root-expressed 9-lipoxygenase (9-LOX) gene, ZmLOX3, results in dramatic increase in resistance to diverse leaf and stalk pathogens. Despite evident economic significance of these findings, the mechanism behind this increased resistance remained elusive. In this study, we found that increased resistance of the lox3-4 mutants is due to consti...
متن کاملPopulation structure and mating-type genes of Colletotrichum graminicola from Agrostis palustris.
Eighty-seven isolates of Colletotrichum graminicola, mostly from Agrostis palustris, were collected in grass fields, most of which were in Ontario, Canada. Specific primers were designed to amplify the mating-type (MAT) genes and, among 35 isolates tested, all yielded a band of the expected size for MAT2. For six isolates, the MAT2 PCR products were sequenced and found to be similar to that rep...
