“…Although ethylene plays an important role in the softening of peach fruits, the NMF trait in peaches is not related to ethylene production [8]. In our study, the ethylene climateric peak was reached faster in NMF than MF fruits, while the peak of ethylene production is higher in MF SH than that of NMF GG, which is in agreement with the results of Haji [7]. However, Kao et al and Onelli et al reported that the NMF cultivars generally had higher ethylene production at harvest and throughout ripening than the MF cultivars [48,51].…”

“…Ethylene release is closely related to fruit softening [3][4][5][6]. However, Haji reported that both MF and NMF mature peaches showed increased endogenous ethylene production and softer flesh, although the degrees differed [7], and Brovelli et al also indicated that NMF trait in peaches is not related to low ethylene production rates. Therefore, there is no clear link between ethylene production and softening in NMF fruits [8].…”

SEPALLATA genes are members of a subfamily of MADS-box transcription factors, and have essential roles in floral organ development and fruit ripening. In this study, the PrupeSEP1 gene was cloned from peach flesh. Its deduced amino acid sequence was very similar to that of MdMADS8 and MdMADS9 in apple and MADS-RIN-like in strawberry. During storage of melting flesh (MF) peach, the pattern of SEP1 expression was similar to that of ethylene biosynthesis and ethylene signal transduction-related gene expression (EIN2 and ETR2). The SEP1 expression level was correlated with that of EIN2 and ETR2. Furthermore, in MF, cell wall modification-related genes (Endo-PG3, EXP2 and PME3), N-glycan processing genes (β-Hex2 and α-Man) and Lox1 exhibited similar expression patterns to that of SEP1. However, in non-melting flesh (NMF) peach, the SEP1 expression pattern was different from that of MF peach. Moreover, in NMF, only EXP2, LOX1, and α-Man expression patterns were similar to that of SEP1. After SEP1 expression was inhibited by virus-induced gene silencing technique (VIGS) in MF peach, compared with the control, the fruit remained firm and fruit softening was delayed. While expression levels of the ripening and softening related genes, ACS2, EIN2, PME1, Endo-PG3, ACO1, ETR2,β-Hex2 and Lox1, were significantly decreased in SEP1-silenced peach, the transcription of EXP2 and PME3 were significantly enhanced except at the harvest stage. Yeast one-hybrid verification showed SEP1 can interact with promoter of target genes PGs. Our results indicate SEP1 may regulate fruit ripening and softening of MF peaches, while this regulation may be lost in the NMF peaches.

“…This result could be supported by previous reports from comparisons made during the fruit ripening stage of melting and stony hard (SH) peach varieties, in which the latter was characterized by the absence of ethylene production and fruit softening. In fact, differential expression of several auxin-homeostasis-related genes, as well as a differential IAA accumulation, were observed, associated to low IAA concentration in the SH peach variety (Haji et al, 2003; Haji, 2014; Pan et al, 2015).…”

Expression QTL (eQTLs) Analyses Reveal Candidate Genes Associated With Fruit Flesh Softening Rate in Peach [Prunus persica (L.) Batsch]

Significant differences in softening rate have been reported between melting flesh in peach and nectarine varieties. This trait seems to be controlled by several genes. We aimed to identify candidate genes involved in fruit softening rate by integrating quantitative trait loci (QTL) and expression QTL (eQTL) analyses, comparing siblings with contrasting softening rates. We used a segregating population derived from nectarine cv. ‘Venus’ selfing, which was phenotyped for softening rate during three seasons. Six siblings with high (HSR) and six with low softening rate (LSR) were sequenced using RNA-Seq. A group of 5,041 differentially expressed genes was identified. Also, we found a QTL with a LOD (logarithm of odds) score of 9.7 on LG4 in all analyzed seasons. Furthermore, we detected 1,062 eQTLs, of which 133 were found co-localizing with the identified QTL. Gene Ontology (GO) analysis showed ‘Response to auxin’ as one the main over-represented categories. Our findings suggest over-expression of auxin biosynthetic related genes in the HSR group, which implies a higher expression and/or accumulation of auxin, thereby triggering fast softening. Conversely, the LSR phenotype might be explained by an altered auxin-homeostasis associated with low auxin levels. This work will contribute to unraveling the genetic mechanisms responsible for the softening rate in peaches and nectarines and lead to the development of molecular markers.

“…Stony hard peaches are characterized by the absence of both ethylene production and softening in mature fruits and are expected to be used as a genetic source for breeding new table peaches ( Haji, 2014 ). However, stony hard fruits are often very difficult to distinguish from NM or very firm, unripe M phenotypes in the field, thereby making reliable selection difficult ( Bassi and Monet, 2008 ; Byrne et al , 2012 ).…”
