Machine learning‐driven GWAS uncovers novel candidate genes for resistance to frosty pod rot and witches' broom disease in cacao

The Plant Genome, Volume 18, Issue 3, September 2025.
Abstract Cacao (Theobroma cacao), the source of chocolate, is threatened by devastating diseases like frosty pod rot (FPR) and witches' broom disease (WBD), impacting global production and farmer livelihoods. Here, we employ a machine learning‐driven genome‐wide association study to dissect the genetic architecture of disease resistance and ...

Cacao Phylloplane: The First Battlefield againstMoniliophthora perniciosa, Which Causes Witches’ Broom Disease [PDF]

Phytopathology®, 2017
The phylloplane is the first contact surface between Theobroma cacao and the fungus Moniliophthora perniciosa, which causes witches’ broom disease (WBD). We evaluated the index of short glandular trichomes (SGT) in the cacao phylloplane and the effect of irrigation on the disease index of cacao genotypes with or without resistance to WBD, and ...

Bioinformatic analysis of glutathione peroxidase family from theobroma cacao and gene expression during Moniliophthora perniciosa infection.[Poster-B185] [PDF]

, 2018
Glutathione peroxidases (GPXs) are enzymes which are part of the antioxidant system of the cell. Mammalian GPXs are known as selenoproteins because containing the selenocysteine (Sec) amino acid. In plants, these proteins are less known.

Unveiling novel mechanisms of strobilurin resistance in the cacao pathogen Moniliophthora perniciosa

bioRxiv
Witches’ broom disease (WBD) is a major constraint for cacao production in the Americas. The severe socioeconomic impact of WBD encouraged the evaluation of different control strategies, including the use of strobilurin fungicides.

The American cocoa pod borer, Carmenta foraseminis, an emerging pest of cocoa: A review El barrenador americano de la mazorca de cacao, Carmenta foraseminis, una plaga emergente del cacao: una revisión

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 340-356, August 2025.
Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,
