High-Affinity Copper Transport and Snq2 Export Permease of Saccharomyces cerevisiae Modulate Cytotoxicity of PR-10 from Theobroma cacao

Molecular Plant-Microbe Interactions, 2009
A pathogenesis-related (PR) protein from Theobroma cacao (TcPR-10) was identified from a cacao–Moniliophthora perniciosa interaction cDNA library. Nucleotide and amino acid sequences showed homology with other PR-10 proteins having P loop motif and Betv1

Moniliophthora perniciosa, the causal agent of witches’ broom disease of cacao, interferes with cytokinin metabolism during infection of Micro‐Tom tomato and promotes symptom development [PDF]

, 2021
Moniliophthora perniciosa causes witches' broom disease of cacao and inflicts symptoms suggestive of hormonal imbalance. We investigated whether infection of the tomato (Solanum lycopersicum) model system Micro-Tom (MT) by the Solanaceae (S)-biotype of ...

Genomic and Transcriptomic Analyses Provide Insights Into Erysiphe necator Pathogenicity and Grapevine Response

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4599-4618, July 2026.
ABSTRACT Grapevine powdery mildew, caused by the fungus Erysiphe necator, is one of the most prevalent obligate biotrophic pathogens in vineyards, posing a significant threat to grape production. Despite its impact, research on E. necator pathogenicity and grapevine responses remains limited.

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...
