Abstract:

The harvesting and storing of alfalfa is a routine practice in the agricultural industry worldwide. A study of the physiological and biochemical changes that occur after harvesting may help to understand how plants respond to this process. To investigate gene expression in harvested alfalfa (Medicago sativa), cDNA from non-harvested and harvested plants in the field was subjected to subtractive hybridization to identify, in particular, those genes that are induced by the harvesting treatment. Three different genes, named, hi7, hi11 and hi12, were isolated and analyzed. Northern blot analysis confirmed that hi7, hi11 and hi12 are strongly induced during a post-harvest incubation period. The promoters of these genes were isolated and characterized. Reporter gene driven by the promoter has been transformed into transgenic plants
