Relative expression profiles of selected genes in leaf, flower and fruit at different stages of development (S1, S2, S3I, S3II, S4I, and S4II, corresponding to 40, 65, 85, 95, 115 and 120 days after full bloom, respectively; sector A), in fruit at S3II following ethylene (ET) and NAA treatment (sector B) and in preclimacteric S4 fruits belonging to class 0 (cl0) or class 1 (cl1) treated with 1-MCP (sector C). Genes belonging to the ethylene domain (upper group), auxin domain (second group), transcription factors (third group) or with the unexpected transcriptional response following 1-MCP treatment are grouped. Genes belonging to the same family are boxed. Expression values, determined by qRT-PCR, were related to the highest expression of each gene (100 %, blue) within each experiment (a, b carried out with RH samples and c, carried out with SRG fruits; both RH and SRG produce melting flesh fruits). ppa no. indicate the peach gene identifier as described in [30], while CTG name indicate the cDNA identifiers on the microarray μPEACH1.0 as described in [28]. Hormone treatments (ET: ethylene; NAA: 1-naphthalene acetic acid, a synthetic auxin) lasted for 48 h (group B). SRG fruits were collected at commercial maturity date and sampled after 36 h of storage either in air or in 1-MCP (12 h) plus air (i.e. 24 h in air after the end of the 1-MCP treatment; group C)
