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.
