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 ...

Proteomic profile of the fungus Moniliophthora perniciosa in response to PR10 from Theobroma cacao : [Abstract R9140] [PDF]

, 2011
Witches' broom disease is caused by the hemibiotrophic basidiomycete Moniliophthora perniciosa. This pathogen is the main cause of the decline in cocoa production, and consequently of social, economic and environmental problems.

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.

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 ...

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,

Evaluation of the allergenicity potential of TcPR-10 protein from Theobroma cacao. [PDF]

PLoS ONE, 2012
BACKGROUND: The pathogenesis related protein PR10 (TcPR-10), obtained from the Theobroma cacao-Moniliophthora perniciosa interaction library, presents antifungal activity against M. perniciosa and acts in vitro as a ribonuclease.

The pathogenesis-related protein PR-4 from Theobroma cacao has antifungal activity and induces ROS in Moniliophthora perniciosa : S03O02 [PDF]

, 2013
The pathogenesis-related proteins class 4 (PR-4) are known to be involved in plant defense response and/or related stress situations. The objective of this study was to evaluate the antifungal activity and reactive oxygen species (ROS) production of the ...
