Using the modified rapid amplification of cDNA ends (5'-RACE) approach, a fragment containing the 955 bp long 5'-regulatory region of the buckwheat storage globulin gene (FeLEG1) has been amplified from the genomic DNA of buckwheat. The entire fragment was sequenced, and the sequence was analyzed by computer prediction of cis-regulatory elements possibly involved in tissue-specific and developmentally controlled seed storage protein gene expression. The promoter obtained might be interesting not only for fundamental research but also as a useful tool for biotechnological application.
