Association mapping reveals the genetic architecture of tomato response to water deficit: focus on major fruit quality traits.

Water scarcity constitutes a crucial constraint for agriculture productivity. High-throughput approaches in model plant species identified hundreds of genes potentially involved in survival under drought, but few having beneficial effects on quality and yield. Nonetheless, controlled water deficit may improve fruit quality through higher concentration of flavor compounds.

Genotype by watering regime interaction in cultivated tomato: lessons from linkage mapping and gene expression.

Key Message: In tomato, genotype by watering interaction resulted from genotype re-ranking more than scale changes. Interactive QTLs according to watering regime were detected. Differentially expressed genes were identified in some intervals.
