Apoplastomes of contrasting cacao genotypes to witches' broom disease reveals differential accumulation of PR proteins.

Witches' broom disease (WBD) affects cocoa trees ( L.) and is caused by the fungus that grows in the apoplast in its biotrophic phase and later progresses into the tissues, causing serious losses in the production of cocoa beans. Therefore, the apoplast of can provide important defense responses during the interaction with .

Structural and Functional Genomics of the Resistance of Cacao to .

Black pod disease, caused by spp., is one of the main diseases that attack cocoa plantations. This study validated, by association mapping, 29 SSR molecular markers flanking to QTL (Quantitative Trait Loci) associated with Butler (Butler) (PP) resistance, in three local ancient varieties of the Bahia (Comum, Pará, and Maranhão), varieties that have a high potential in the production of gourmet chocolate.
