Gene expression between canopy positions suggests a persistent effect of phased at-harvest fruit maturity. Gene expression for both tissue types was of a fairly consistent magnitude throughout the experiment, which spanned 8 months of controlled atmosphere storage at −0.5°C. This contrasts with the initially large and waning magnitude of patterns of differential expression through time in storage, and indicates the possibility that gene expression signatures may be useful to predict fruit quality at and after harvest. Significant differential expression determined by Bonferroni corrected P < 0.05.
