In the recent
period, systematic comparisons have been performed at the transcriptome level between fruit
belonging to the same genus, the same family (Solanaceae, Moore et al. 2002) but also between
fruit from distantly related families like tomato and grape (Solanaceae and Vitacea). These
studies highlighted the interest of such approaches for deciphering the metabolic pathways
leading to the accumulation of compounds (vitamin C, carotenoids, anthocyanins, organic
acids) with high nutritional or sensorial value in the fruit, and for understanding the regulation
of fruit-specific processes such as ripening.
