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.
