Effects of Antisense Thioredoxin s on Starch Accumulation and Expressions of Enzymes Related to Starch Synthesis in Weak-gluten Wheat Cultivar Yumai 18
To clarify the functional mechanisms of starch accumulation by the antisense-thioredoxin s(anti-Trxs)gene into wheat,we conducted a pot experiment using two transgenic wheat lines,TY18-99 and TY18-100,and their wild type Yumai 18 from October 2007 to June 2009.The effects of the anti-Trxs on starch accumulation and key enzymes involved in starch synthesis were compared between the transgenic lines and the wild type.Results indicated that the rates of starch and amylopectin accumulations in grain were signif...
