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
Theobroma cacao L. plants over-expressing a cacao class I chitinase gene (TcChi1) under the control of a modified CaMV-35S promoter were obtained by Agrobacterium-mediated transformation of somatic embryo cotyledons. Southern blot analysis confirmed insertion of the transgene in eight independent
Programmed cell death (PCD) plays a key role in plant responses to pathogens, determining the success of infection depending on the pathogen lifestyle and on which participant of the interaction triggers cell death. The hemibiotrophic basidiomycete Moniliophthora perniciosa is the causal agent of
BACKGROUND
The stem bark of Theobroma cacao L. have been used for the treatment of inflammation, toothache, measles and malaria in ethnomedicine. However, the anti-inflammatory activity of Theobroma cacao stem bark has not been fully elucidated.
OBJECTIVE
The anti-inflammatory activity of Theobroma
Developmental expression of stress response genes in Theobroma cacao leaves and their response to Nep1 and a compatible infection by Phytophthora megakarya were studied. Ten genes were selected to represent genes involved in defense (TcCaf-1, TcGlu1,3, TcChiB, TcCou-1, and TcPer-1), gene regulation
Pathogenesis-related proteins (PRs) are induced in plants after infection by pathogens and/or abiotic stress. Among these proteins, the family 10 (PR-10) influences the biosynthesis of secondary metabolites and shows antimicrobial ribonuclease activity. TcPR-10p (Pathogenesis-related Protein 10 of
In the present study, we report the effects of a cocoa extract on the secretion and RNA expression of various proinflammatory mediators by macrophages. Monocyte chemoattractant protein 1 and tumor necrosis factor alpha (TNFalpha) were significantly and dose-dependently diminished by cocoa extract,
Drought can negatively impact pod production despite the fact that cacao production usually occurs in tropical areas having high rainfall. Polyamines (PAs) have been associated with the response of plants to drought in addition to their roles in responses to many other stresses. The constitutive and
Three cystatin open reading frames named TcCys1, TcCys2 and TcCys3 were identified in cDNA libraries from compatible interactions between Theobroma cacao (cacao) and Moniliophthora perniciosa. In addition, an ORF named TcCys4 was identified in the cDNA library of the incompatible interaction. The
