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 pPloS onee90706https://www.ebi.ac.uk/biostudies/studies/S-EPMC3944608biostudies-literatureA bulk segregant gene expression analysis of a peach population reveals components of the underlying mechanism of the fruit cold response.PMC3944608Forment JCrisosto CHPons CMarti CDandekar AMGranell AfalseA 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.
