Vegetative compatibility and genetic analysis of Colletotrichum lindemuthianum isolates from Brazil.
The causal agent of common bean anthracnose, Colletotrichum lindemuthianum, has considerable genetic and pathogenic variability, which makes the development of resistant cultivars difficult. We examined variability within and between Brazilian pathotypes of C. lindemuthianum through the identification of vegetative compatibility groups (VCGs) and by RAPD analysis. Two hundred and ninety-five ni...
متن کاملGenetic relatedness of Brazilian Colletotrichum truncatum isolates assessed by vegetative compatibility groups and RAPD analysis.
The genetic variation among nine soybean-originating isolates of Colletotrichum truncatum from different Brazilian states was studied. Nitrate non-utilizing (nit) mutants were obtained with potassium chlorate and used to characterize vegetative compatibility reactions, heterokaryosis and RAPD profile. Based on pairings of nit mutants from the different isolates, five vegetative complementation ...
متن کاملVegetative Compatibility and Heterokaryon Formation between Different Isolates of Colletotrichum Lindemuthianum by using the nit Mutant System
Colletotrichum lindemuthianum, the causative agent of bean anthracnose, is one of the most common pathogens leading to expressive damage to plants beyond presenting noticeable variability. The knowledge on vegetative compatibility groups (VCGs) is of particular interest in asexual fungi as they subdivide the population in groups that can exchange genetic information via heterokaryosis and the p...
متن کاملVegetative compatibility and parasexual segregation in Colletotrichum lindemuthianum, a fungal pathogen of the common bean.
The heterokaryotic and vegetative diploid phases of Colletotrichum lindemuthianum are described using nutritional and biochemical markers. Nitrate non-utilizing mutants (nit), derived from R2047, R89, R73, R65, and R23 isolates, were paired in all possible combinations to obtain heterokaryons. Although pairings R2047/R89, R2047/R73, R65/R73, and R73/R23 showed complete vegetative incompatibilit...
متن کاملKinetic studies of the polygalacturonase enzyme from Colletotrichum lindemuthianum.
The intrinsic protein fluorescence of the polygalacturonase from Colletotrichium lindemuthianum was exploited in stopped-flow experiments aimed at elucidating the kinetic mechanism for this enzyme. Binding of the polymeric substrate polygalacturonic acid (PGA) essentially produced a triphasic fluorescence profile. There was an initial rapid quench in fluorescence, consistent with the rapid form...
