Abstract
Myo-inositol metabolism in plant edible organs has become the focus of many recent studies because of its benefits to human health and unique functions in plant development. In this study, myo-inositol contents were analyzed during the development of two blueberry cultivars, cv 'Berkeley' and cv 'Bluecrop'. Furthermore, two VcMIPS 1/2 (Vaccinium corymbosum MIPS) genes, one VcIMP (Vaccinium corymbosum IMP) gene and one VcMIOX (Vaccinium corymbosum MIOX) gene were isolated for the first time from blueberry. The expression patterns of VcMIPS2, VcIMP and VcMIOX genes showed a relationship with the change profiles of myo-inositol content during fruit ripening. The results were further confirmed by the analyses of the enzyme activity. Results indicated that both myo-inositol biosynthesis and oxidation played important roles in determining of myo-inositol levels during the development of blueberry. To our knowledge, this report is the first to discuss myo-inositol levels in fruits in terms of biosynthesis and catabolism.
