Bread wheat (T.aestivum) is one of the most important crops in the world, yet studies about it lags far behind small genome organisms, such as O. sativa. A. thaliana, etc. Up to date, only a few wheat genes were cloned because of its large genome (1.6 1010bp) and redundant repeat sequences (about 90 % ) . As most of clones from full-length cDNA library contained not only the CDS but also the UTRs of 5' and 3' regions, which facilitate the progress of later researches such as sequencing, structural and funct...
