Among the 478 functional primers from wheat, 255 EST-SSRs amplified fragments in rice, maize and soybean too, indicating high degree of transferability between species, which facilitated comparative mapping and homologous gene cloning.

• 同时，478对小麦EST-SSR引物用于水稻，玉米和大豆研究，结果表明，有255对EST-SSR引物可以在这四种作物中有效扩增，证明物种间DNA序列具有很高的保守性，这将有利于在不同作物间进行比较作图和同源基因克隆。
