Complete genomic DNA sequences of the Waxy genes encoding granule-bound starch synthase (GBSS) proteins of tetraploid (Triticum aestivum L. cv. Chinese Spring) and hexaploid (T. turgidum L. spp. dicoccoides var. spontaneonigrum, T. turigidum L. spp. Durum cv. Stewart) wheats were completely determined. The DNA sequences were closely similar to one another (87.9 % - 99.5 %) in the entire regions. According to the sequence similarity, the genes were classified into subtypes, and the processes of the GBSS gene evolution and the species establishment of wheats are proposed.

四倍体小麦（Triticum aestivum L. cv.）颗粒结合淀粉合成酶（GBSS）蛋白编码Waxy基因全基因组DNA序列。中国春)和六倍体(T. turgidum L. spp. dicoccoides var. spontaneonigrum， T. turigidum L. spp. Durum cv。斯图尔特)小麦是完全确定的。整个区域的DNA序列非常相似（87.9% ~ 99.5%）。根据序列相似性对基因进行了分类，并提出了小麦GBSS基因的进化过程和物种建立过程。
