Association of genes from different sources of resistance to major cacao diseases

Revista Ceres, 2020
This study aimed to select genotypes resistant to witches’ broom (WB) and black pod (BP), major cacao diseases in Brazil, as well as incorporate resistance genes to moniliasis supplemented by clones EET75 and UF273, forming populations of second-cycle ...

Genetic diversity of polysporic isolates of Moniliophthora perniciosa (Tricholomataceae)

Genetics and Molecular Research, 2012
The causal agent of witches' broom disease, Moniliophthora perniciosa is a hemibiotrophic and endemic fungus of the Amazon basin and the most important cocoa disease in Brazil. The purpose of this study was to analyze the genetic diversity of polysporic isolates of M.

Saprotrophic proteomes of biotypes of the witches' broom pathogen Moniliophthora perniciosa [PDF]

Fungal Biology, 2017
Nine geographically diverse Moniliophthora perniciosa (witches' broom disease pathogen) isolates were cultured in vitro. They included six C-biotypes differing in virulence on cacao (Theobroma cacao), two S-biotypes (solanaceous hosts), and an L-biotype (liana hosts).

High-Affinity Copper Transport and Snq2 Export Permease of Saccharomyces cerevisiae Modulate Cytotoxicity of PR-10 from Theobroma cacao

Molecular Plant-Microbe Interactions, 2009
A pathogenesis-related (PR) protein from Theobroma cacao (TcPR-10) was identified from a cacao–Moniliophthora perniciosa interaction cDNA library. Nucleotide and amino acid sequences showed homology with other PR-10 proteins having P loop motif and Betv1
