Induction of systemic resistance in Theobroma cacao L. for the management of “witches’ broom” caused by Moniliophthora perniciosa

The fungus, the witches' broom, and the chocolate tree: deciphering the molecular interplay between Moniliophthora perniciosa and Theobroma cacao.

A potential role for an extracellular methanol oxidase secreted by Moniliophthora perniciosa in Witches' broom disease in cacao.

The hemibiotrophic basidiomycete fungus Moniliophthora perniciosa, the causal agent of Witches' broom disease (WBD) in cacao, is able to grow on methanol as the sole carbon source. In plants, one of the main sources of methanol is the pectin present in the structure of cell walls. Pectin is composed of highly methylesterified chains of galacturonic acid. The hydrolysis between the methyl radica...

Characterization of necrosis and ethylene-inducing proteins (NEP) in the basidiomycete Moniliophthora perniciosa, the causal agent of witches' broom in Theobroma cacao.

The hemibiotrophic basidiomycete Moniliophthora perniciosa causes witches' broom disease of Theobroma cacao. Analysis of the M. perniciosa draft genome led to the identification of three putative genes encoding necrosis and ethylene-inducing proteins (MpNEPs), which are apparently located on the same chromosome. MpNEP1 and 2 have highly similar sequences and are able to induce necrosis and ethy...

Moniliophthora perniciosa, the causal agent of witches' broom disease of cacao: what's new from this old foe?

UNLABELLED Moniliophthora perniciosa (=Crinipellis perniciosa) causes one of the three main fungal diseases of Theobroma cacao (cacao), the source of chocolate. This pathogen causes Witches' broom disease (WBD) and has brought about severe economic losses in all of the cacao-growing regions to which it has spread with yield reductions that range from 50 to 90%. Cacao production in South America...

Restriction Enzyme Improves the Efficiency of Genetic Transformations in Moniliophthora perniciosa, the Causal Agent of Witches’ Broom Disease in Theobroma cacao

The presence of restriction enzymes in the transformation mixture improved the efficiency of transformation in Moniliophthora perniciosa. The influence of the vector shape (linear or circular), the patterns of plasmid integration in genomic sites and the influence of the promoter used to express the gene marker were also analyzed. The addition of BamHI or NotI increased the number of transforma...
