Clovamide presence in disease-resistant chocolate tree leaves may spur novel breeding program The researchers have created a streamlined sample-collection protocol that only requires a single leaf disc. The leaf discs are preserved in a solvent that prevents degradation of clovamide, allowing large-scale sampling in greenhouses and fields without the need for refrigeration.  Image: Ben Knollenberg/Penn State Discovery of chemical clue may lead to solving cacao's black pod rot mystery Jeff Mulhollem December 23, 2020 UNIVERSITY PARK, Pa. — The finding of relatively high levels of the antimi...

The discovery is significant because...
