Starch serves not only as an energy source forplants, animals, and humans but also as an environmentallyfriendly alternative for fossil fuels. Progress in understandingof starch biosynthesis, and the isolation of many genesinvolved in this process have enabled the genetic modificationof crops in a rational manner to produce novel starches withimproved functionality. Starch is composed of two glucosepolymers, amylose and amylopectin. The amylose and amylopectinratio in starch affects its physical and physicochemicalproperties. Alteration in starch structure can beachieved by modifying genes encoding the enzymesresponsible for starch biosynthesis and starch hydrolysis.Here, we describe recent findings concerning the starchmodification in sweetpotato. Sweetpotato [Ipomoea batatas(L.) Lam] ranks seventh in annual production among foodcrops in the world as an important starch source. To developtransgenic sweetpotato plants with modifying starch composition,we constructed transformation vectors overexpressinggranule bound starch synthase I and inhibitingamylopectin synthesis genes such as starch branchingenzyme and isoamylase under the control of 35S promoter,respectively. Transformation of sweetpotato (cv. Yulmi) isin progress. |
