Cupuassu (Theobroma grandiflorum [Willd. ex Sprengel] Schumann) Fruit Development: Key Genes Involved in Primary Metabolism and Stress Response

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 large-scale development cupuassu plantations. genetic breeding programmes focus on a variety biotechnological tools or approaches select genes related quality resistance mechanisms. In this study, we used expression interactomics analyses preselected involved in fruit and/or better understand molecular physiological mechanisms associated these plant processes. It was found that (i) resistant susceptible genotypes showed different pulp characteristics well gene patterns; (ii) monosaccharide carbohydrate transport pathways were enhanced during maturation; (iii) sugar accumulation participated signal transduction stress response maturing fruits; (iv) increased phospholipid metabolism translocation, immune system activation. The TgSTP1, TgWRKY33, TgCZF1, TgUBA1 orthologues DIN10, CNI1, TET8 identified approach may be good candidates marker-assisted selection focusing both resistance/tolerance biotic/abiotic stress.
