“…The environmental effect on the mealy phenotype has been described (Campos-Vargas et al 2006), and the contribution to phenotypic variance has been estimated to be between 36.5 and 57.5 % in peach biparental populations (Peace et al 2005;Cantín et al 2010). These results are consistent with the correlation values obtained between phenotyping seasons for M in this work (approximately 0.7 between seasons).…”

Artículo de publicación ISIPeach and nectarine quality traits such as flavor, texture, and juiciness are important for consumer acceptance. Maturity date (MD) also plays a role in the fruit-ripening process and is an important factor for marketing fresh fruit. On the other hand, cold storage produces a physiological disorder known as chilling injury where the most important symptom is a lack of juice in the flesh or mealiness (M). In this study, we analyzed an F2 population obtained from a self-pollination of "Venus" nectarine that segregates for MD and M. We built a linkage map with 1,830 SNPs, 7 SSRs and two slow-ripening (SR) morphological markers, spanning 389.2 cM distributed over eight linkage groups (LGs). The SR trait was mapped to LG4 and we compared the whole genome sequences of a SR individual and "Venus" and identified a deletion of 26.6 kb containing ppa008301m (ANAC072) co-localized with the SR trait. Three Quantitative Trait Loci (QTL) for MD were detected; they all co-localize on LG4 between 31.0 and 42.0 cM. Four co-localizing QTLs on LG4 between 33.3 and 40.3 cM were detected for M, explaining 34 % of the phenotypic variation. We identified five and nine candidate genes (CGs) for MD and M from the QTL regions, respectively. Our results suggest that the transcription factors (TFs) ANAC072 and ppa010982m (ERF4) are CGs for both traits. LG4 contains a cluster for genetic factors that possibly regulate MandMD, but functional validation is necessary to unravel the complexity of genetic control responsible for fruit traits.Conicyt-Fondecyt 11121396 Conicyt-FONDEF G13i10005 Corfo-Innova 09PMG-7240 Fondo de Areas Prioritarias Centro de Regulacion del Genoma 15090007 UNAB DI-489-14R CONICYT D-21090737 PFB-1

“…Strong year effects are commonly observed in multi-year performance trials for peach (Etienne et al 2002;Campos-Vargas et al 2006;Crisosto 2002;Peace et al 2005) and underscore the need to evaluate individual trees over multiple seasons to understand the relative effects of genotypic and phenotypic factors on CI. Although statistically significant, the effect of year was relatively minor compared to differences among seedlings for the major CI symptoms.…”

Influence of year and genetic factors on chilling injury susceptibility in peach (Prunus persica (L.) Batsch)

Chilling injury (CI) is a major physiological problem limiting consumption and export of peach and nectarine (Prunus persica (L.) Batsch). To clarify the genetic basis for chilling injury, inheritance of the major CI symptoms mealiness, flesh browning, flesh bleeding, and flesh leatheriness were examined over three years in two related peach progenies. In addition, genetic relationships among traits and the year-to-year variation in trait performance in these progenies were tracked. Both populations also segregated for Freestone-Melting flesh (F-M) and yellow flesh. There were significant differences in CI symptoms among years. The major gene endoPG, which controls the F-M locus, provides resistance to mealiness in nonmelting flesh fruit. Only fruit with melting flesh can develop mealiness if the tree possesses other genetic susceptibility factors and/or experiences inducing conditions. The F-M locus also greatly influences susceptibility to flesh bleeding, although the physiological mechanism for this disorder is unclear and may be controlled by a different gene closely linked to endoPG. Unlike mealiness, flesh bleeding occurred primarily in non-melting flesh fruit, particularly when the fruit is white-fleshed. Flesh browning incidence was greater in mealy fruit and was not associated with flesh bleeding. Breeding for CI resistance is thus a viable long-term strategy to reduce losses in the fresh and processed peach and nectarine industries. This study is an important first step to understanding genetic control of CI symptoms in peach.

“…During cold storage physiological alterations has been described. Firmness and ethylene production were reduced [41], [44]. Alterations in cell wall transcriptome, enzyme activity and in cell wall polymers metabolism still occur during cold storage, which affect in the manner fruits ripened during subsequent shelf life [39], [41].…”

A Bulk Segregant Gene Expression Analysis of a Peach Population Reveals Components of the Underlying Mechanism of the Fruit Cold Response

Peach fruits subjected for long periods of cold storage are primed to develop chilling injury once fruits are shelf ripened at room temperature. Very little is known about the molecular changes occurring in fruits during cold exposure. To get some insight into this process a transcript profiling analyses was performed on fruits from a PopDG population segregating for chilling injury CI responses. A bulked segregant gene expression analysis based on groups of fruits showing extreme CI responses indicated that the transcriptome of peach fruits was modified already during cold storage consistently with eventual CI development. Most peach cold-responsive genes have orthologs in Arabidopsis that participate in cold acclimation and other stresses responses, while some of them showed expression patterns that differs in fruits according to their susceptibility to develop mealiness. Members of ICE1, CBF1/3 and HOS9 regulons seem to have a prominent role in differential cold responses between low and high sensitive fruits. In high sensitive fruits, an alternative cold response program is detected. This program is probably associated with dehydration/osmotic stress and regulated by ABA, auxins and ethylene. In addition, the observation that tolerant siblings showed a series of genes encoding for stress protective activities with higher expression both at harvest and during cold treatment, suggests that preprogrammed mechanisms could shape fruit ability to tolerate postharvest cold-induced stress. A number of genes differentially expressed were validated and extended to individual genotypes by medium-throughput RT-qPCR. Analyses presented here provide a global view of the responses of peach fruits to cold storage and highlights new peach genes that probably play important roles in the tolerance/sensitivity to cold storage. Our results provide a roadmap for further experiments and would help to develop new postharvest protocols and gene directed breeding strategies to better cope with chilling injury.
