Conteúdo:

Cupuassu (Theobroma grandiflorum [Willd. ex Sprengel] Schumann) seeds constitute the raw material for oil extraction and fabrication of cupulate (product similar to chocolate). However, fungal diseases such as witches? broom caused by Moniliophthora perniciosa have interfered with the large-scale development of cupuassu plantations. Cupuassu genetic breeding programmes focus
on a variety of biotechnological tools or approaches to select genes related to quality or resistance mechanisms. In this study, we used expression and interactomics analyses of preselected genes
involved in fruit quality and/or resistance to better understand the molecular and physiological mechanisms associated with these plant processes. It was found that (i) resistant and susceptible
cupuassu genotypes showed different pulp characteristics as well as gene expression patterns; (ii) monosaccharide and carbohydrate transport pathways were enhanced during fruit maturation;
(iii) sugar accumulation participated in signal transduction associated with fruit development and stress response in maturing fruits; and (iv) maturing pulp and seeds showed increased phospholipid
metabolism and translocation, as well as immune system activation. The TgSTP1, TgWRKY33, TgCZF1, and TgUBA1 genes in cupuassu and the orthologues of DIN10, CNI1, and TET8 identified
by the interactomics approach may be good candidates for marker-assisted selection in breeding programmes focusing on both fruit quality and resistance/tolerance to biotic/abiotic stress.
