The main goal of this work was to select resistance sources to common bean anthracnose by field phenotyping and DNA marker-assisted screening. Fifty-five common bean genotypes, including differential varieties, characterized resistance sources, elite lines, cultivars and controls, were evaluated in a field inoculation trial an.. Read More»

Structural and functional characterization of the Colletotrichum lindemuthianum nit1 gene, which encodes a nitrate eductase enzyme
Authors: G.B. Nogueira M.V. Queiroz R.A. Ribeiro E.F. Ara�ºjo
Colletotrichum lindemuthianum is the causal agent of plant bean anthracnose, one of the most important diseases affecting the common bean. We investigated the structure and expression of the nit1 gene (nitrate reductase) of C. lindemuthianum. The nit1 gene open reading frame contains 2787 bp, interrupted by a single 69-bp intron. The predicted protein has 90.. Read More»

Identification of Glomerella cingulata f. sp phaseoli recombinants by RAPD markers
Authors: O.A. Camargo Junior, E.A. Souza, M.C. Mendes-Costa, J.B. Santos, M.A. Soares
We examined the capacity of strains of Glomerella cin-gulata f. sp phaseoli fungus (Colletotrichum lindemuthianum sexual stage) to form recombinants, using random amplified polymorphic DNA (RAPD). Crosses of all possible combinations between strains 40, 42, 20, 21, 22, 23, 24, 25, and 26 were made on Petri dishes using M3 cult.. Read More»

Vegetative compatibility and parasexual segregation in Colletotrichum lindemuthianum, a fungal pathogen of the common bean
Authors: M.A.A. Castro-Prado, C.B. Querol, J.R. Sant�Anna, C.T. Miyamoto, C.C.S. Franco, C.A. Mangolin, M.F.P.S. Machado
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, R204..

Variability of Colletotrichum spp in common bean
Authors: S.F. Mota, Q.L. Barcelos, M.A. Dias and E.A. Souza
The Colletotrichum genus presents large genetic variability, as demonstrated by the occurrence of several pathogenic races and phenotypic traits. The objective of this study was to characterize 22 strains of C. lindemuthianum and Colletotrichum spp recovered from anthracnose lesions and bean scab, and to verify the relationshi.. Read More»
