AbstractBlueberry is a widely grown and easily perishable fruit crop. An efficient post-harvest handling is critical, and for that purpose gene technology methods have been part of ongoing programmes to improve crops with high food values such as blueberry. Here we report the isolation, cloning, characterization and differential expression levels of two cDNAs encoding Polygalacturonase-Inhibitor Protein (PGIP) and Cinnamoyl-Coa Reductase (CCR) from blueberry fruits in relation to various storage conditions. The open reading frame of PGIP and CCR encodes a polypeptide of 329 and 347 amino acids, respectively. To assess changes in the expression of blueberry PGIP and CCR after harvest, a storage trial was initiated. The northern blots hybridization showed a clear differential expression level of PGIP and CCR between freshly harvested and stored fruits as well as between fruits stored under various storage conditions. Although the prospects of exploiting such a strategy for crop improvement are limited, the results provide further insight into the control of the quality over the storage period at the molecular level.
