Genomics approaches and transcriptome analyses are increasingly being used to elucidate mechanisms that regulate complex developmental processes such as fruit ripening and the evolution of quality-related biochemical changes during the postharvest phase. In peach (Prunus persica L.), projects aimed at isolating ESTs corresponding to genes expressed in different fruit tissues and the construction and use of tools such as microarrays has resulted in identification of basic information concerning hormonal regulation, in particular on the role of ethylene and auxin and their interplay and cross-talk during ripening. Functional genomics approaches have been undertaken for studies specifically targeted to identify and characterize genes involved in the peculiar response of peaches and nectarines to applications of 1-MCP and in the development of storage disorders.
