外文摘要：A glutathione S-transferase(GST)gene IbGSTL2 was cloned and characterized from sweetpotato.It har-bored a variation associated with starch content in storage roots.Overexpression of IbGSTL2 increased starch content and amylopectin proportion,decreased gelatinization temperature,and improved degree of crystallinity in sweetpotato storage roots,while its RNA interference resulted in the opposite trends.IbGSTL2 physically interacted with IbcPGM,an enzyme of sucrose metabolism,and improve starch con-tent and quality by regulating genes involved in starch biosynthesis.
