The hemibiotrophic cacao pathogen Moniliophthora perniciosa depends on a mitochondrial alternative oxidase for biotrophic development
The tropical pathogen Moniliophthora perniciosa causes witches' broom disease in cacao. As a hemibiotrophic fungus, it initially colonizes the living host tissues (biotrophic phase), and later grows over the dead plant (necrotrophic phase). Little is known about the mechanisms that promote these distinct fungal phases or mediate the transition between them. An alternative oxidase gene (Mp-aox) ...
متن کاملGenetic diversity of polysporic isolates of Moniliophthora perniciosa (Tricholomataceae).
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. perniciosa to evaluate the adaptation of the pathogen from different Brazilian regions and its association with different ...
متن کاملCarbon source-induced changes in the physiology of the cacao pathogen Moniliophthora perniciosa (Basidiomycetes) affect mycelial morphology and secretion of necrosis-inducing proteins.
Quantitative and qualitative relationships were found between secreted proteins and their activity, and the hyphal morphology of Moniliophthora perniciosa, the causal agent of witches' broom disease in Theobroma cacao. This fungus was grown on fermentable and non-fermentable carbon sources; significant differences in mycelial morphology were observed and correlated with the carbon source. A bio...
متن کاملUse of response surface methodology to examine chitinase regulation in the basidiomycete Moniliophthora perniciosa.
We report here the first analysis of chitinase regulation in Moniliophthora perniciosa, the causal agent of the witches' broom disease of cacao. A multivariate statistical approach was employed to evaluate the effect of several variables, including carbon and nitrogen sources and cultivation time, on M. perniciosa non-secreted (detected in mycelium, i.e. in symplasm and cell wall) and secreted ...
متن کاملThe mitochondrial genome of the phytopathogenic basidiomycete Moniliophthora perniciosa is 109 kb in size and contains a stable integrated plasmid.
We present here the sequence of the mitochondrial genome of the basidiomycete phytopathogenic hemibiotrophic fungus Moniliophthora perniciosa, causal agent of the Witches' Broom Disease in Theobroma cacao. The DNA is a circular molecule of 109,103 base pairs, with 31.9% GC, and is the largest sequenced so far. This size is due essentially to the presence of numerous non-conserved hypothetical O...
