Multiple genetic resistances in Capsicum spp
Authors: C.S. Bento, A.G. de Souza, C.P. Sudr�©, S. Pimenta and R. Rodrigues
This study aimed to identify Capsicum genotypes with resistance to bacterial spot (BS), anthracnose and Pepper yellow mosaic virus (PepYMV). Fifty-four genotypes of Capsicum spp were evaluated. Resistance reaction against BS was evaluated using three replicates, testing hypersensitivity and quantitative resistance in leaves. A.. Read More»

Identification of Colletotrichum isolates from Capsicum chinense in Amazon
Authors: C.V.S. de Oliveira, K.S. Matos, D.M.C. de Albuquerque, R.E. Hanada and G.F. da Silva
Chili pepper (Capsicum chinense) is a great economic important culture on the State of Amazonas, and it represents, approximately, a production of 1.9 thousand tons per year. It is one of the hosts of Colletotrichum genus in the North region of Brazil. The aim of the study was to differentiate and to identify isolates of Colle.. Read More»

Phenotypic and molecular characterization of Colletotrichum species associated with anthracnose of banana (Musa spp) in Malaysia
Authors: M.A. Intan Sakinah, I.V. Suzianti and Z. Latiffah
Anthracnose caused by Colletotrichum species is a common postharvest disease of banana fruit. We investigated and identified Colletotrichum species associated with anthracnose in several local banana cultivars based on morphological characteristics and sequencing of ITS regions and of the β-tubulin gene. Thirty-eight Coll.. Read More»

Identification of lipopeptides produced by Bacillus subtilis Czk1 isolated from the aerial roots of rubber trees
Authors: C.P. He, L.Y. Fan, W.H. Wu, Y.Q. Liang, R. Li, W. Tang, X.L. Zheng, Y.N. Xiao, Z.X. Liu and F.C. Zheng
We obtained a strain of Bacillus subtilis, which we named Czk1, from the aerial roots of rubber trees. This bacterial isolate exhibits strong antagonistic activity against Ganoderma pseudoferreum, Phellinus noxius, Helicobasidium compactum, Rigidoporus lignosus, Sphaerostilbe repens, and Colletotrichum gloeosporioides. Our ear.. Read More»

Molecular phylogeny of Colletotrichum (Sordariomycetes: Glomerellaceae) inferred from multiple gene sequences
Authors: H. Chen, Y. Ma, W.F. Zhang, T. Ma and H.X. Wu
The genus Colletotrichum contains many important plant pathogens mainly distributed in tropical areas. Previous studies that utilized morphology or single genes have failed to resolve the phylogenetic relationships among the species. In this study, sequences of β-tubulin, 28S ribosomal DNA, and ITS region from nine species were analyzed separately an.. Read More»

Investigation of mycoviruses in endophytic and phytopathogenic strains of Colletotrichum from different hosts
Authors: P. Rosseto1, A.T. Costa1, J.C. Polonio1, A.A. da Silva1, J.A. Pamphile1and J.L. Azevedo2
Fungi belonging to the Colletotrichum genus can be categorized as endophytic or phytopathogenic. These fungi can be infected by viruses, termed mycoviruses, which are know to promote hypovirulence in infected fungi. However, there are few studies that have described mycoviral infections of endophytes. The production of secondary metabolites by endophytes .. 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..
