Moniliophthora perniciosa (Sthael) (Singer) Phillips-Mora is the causal agent of witches' broom disease, which can infect Theobroma cacao decreasing the production of cocoa about 60%. M. perniciosa has a set of potential enzymes that can be useful targets for design of new inhibitors. After the release of the aminoacid sequence of pyrophosphorylase of M. perniciosa, a comparative modelling approach was carried out to obtain the 3D structure of this target. This model can be useful to develop new inhibitors against witches' broom disease.

Moniliophthora perniciosa is the causal agent of the witches' broom disease of cacao (Theobroma cacao), and it can infect the tomato (Solanum lycopersicum) 'Micro-Tom' (MT) cultivar. Typical symptoms of infection are stem swelling and axillary shoot outgrowth, whereas reduction in root biomass is another side effect. Using infected MT, we investigated whether impaired root growth derives from hormonal imbalance or sink competition.

Unlabelled: Β-glucosidase (BGLs) act synergistically with endoglucanases and exoglucanases and then are of great interest for biomass conversion into bioethanol. Thus, the aim of the current study is to produce a recombinant β-glycosidase from expressed in cells. Enzyme coding sequence expression was confirmed through Sanger sequencing after using wheat bran (WB) and carboxymethylcellulose (CMC) as fungal growth media.

Exploring the intricate relationships between plants and their resident microorganisms is crucial not only for developing new methods to improve disease resistance and crop yields but also for understanding their co-evolutionary dynamics. Our research delves into the role of the phyllosphere-associated microbiome, especially Actinomycetota species, in enhancing pathogen resistance in Theobroma grandiflorum, or cupuassu, an agriculturally valuable Amazonian fruit tree vulnerable to witches' broom disease caused by Moniliophthora perniciosa. While breeding resistant cupuassu genotypes is a possible solution, the capacity of the Actinomycetota phylum to produce beneficial metabolites offers an alternative approach yet to be explored in this context.

Witches' broom disease (WBD) affects cocoa trees ( L.) and is caused by the fungus that grows in the apoplast in its biotrophic phase and later progresses into the tissues, causing serious losses in the production of cocoa beans. Therefore, the apoplast of can provide important defense responses during the interaction with .

causes a destructive disease known as witches' broom disease of cacao (WBDC). WBDC has been responsible for major reductions in production or even total abandonment of cacao plantations in most countries that it has invaded. To date, however, the disease is known only from the cacao-producing regions of South America and a few Central American and Caribbean countries.
