Study of structural variants in cacao genomes yields clues about plant diversity

An exhaustive and painstaking comparison of the genomes of multiple strains of the cacao tree by a team of researchers has provided insights into the role genomic structural variants play in the regulation of gene expression and chromosome evolution, giving rise to the differences within populations of the plant.

Discovery of chemical clue may lead to solving cacao's black pod rot mystery

The finding of relatively high levels of the antimicrobial compound clovamide in the leaves of a disease-resistant strain of cacao has significant implications for breeding trees that can tolerate black pod rot, according to Penn State researchers who conducted a novel study.

New way to identify disease-resistant genes in chocolate-producing trees

Chocolate-producing cacao trees that are resistant to a major pathogen were identified by an international team of plant geneticists. The NSF-funded finding points the way for plant breeders to develop trees that are tolerant of the disease.

These Kids Have Come 500 Miles To Do Science And Make A Difference

The road between Arauquita, relatively near Colombia’s border with Venezuela, and the nation’s capital in Bogota stretches over 800 kilometers (500 miles), but for one week in October, a special group bridged that gap in more ways than one.

Gene editing could save Ghana’s cocoa from extinction, scientists say

A new study warns that climate change could drive Ghana’s cocoa (cacao) industry to extinction — a fate that scientists say could be reversed through gene editing.
