Peach flesh color (white or yellow) is among the most popular commercial criteria for peach classification, and has implications for consumer acceptance and fruit nutritional quality. Despite the increasing interest in improving cultivars of both flesh types, little is known about the genetic basis for the carotenoid content diversity in peach. Here we(More)
The function of monomeric GTPases of the RAS superfamily in fruit development and ripening has been partially characterized. Here the identification of peach (Prunus persica) small GTPases of the RAS superfamily expressed in fruit and the characterization of their expression profiles during fruit development are described. Extensive searches on expressed(More)
Biotechnological innovations that allow one to sample gene expression (e.g. gene-expression arrays or real-time Polymerase Chain Reaction (PCR)), have made it possible to measure the gene expression levels of a biological system with varying degree of accuracy, cost and speed. By repeating the measurement steps at different sampling rates during the system(More)
Peach fruit tissues start differentiating into mesocarp, endocarp, and seed from the first phases of development. A seed is necessary for fruit set, and it may strongly regulate the growth of the whole fruit through metabolic or hormonal signals. Although the importance of sugar and hormone signaling in growing fruit, such as peach, has been analyzed(More)
