WebJun 1, 2008 · An enzyme responsible for amylose synthesis in vivo is granule-bound starch synthase (GBSS), which is usually found as a starch synthase isozyme bound to or embedded in starch granules. In rice, GBSSI is encoded by the Wx gene (Okagaki 1992, Hirose and Terao 2004) which has two functional alleles, Wxa and Wxb (Sano 1984 ). WebBased on known cDNAs of rice starch synthase isoforms,we constructed dsRNA interference vectors for starch synthase I(SSI)to produce transgenic plants containing starch with a moderately high amylose content.We investigated the effect of SSI suppression on grain quality traits,starch biosynthesis,and amylopectin chain distribution …
