WebOct 20, 2024 · Granule-bound starch synthase (GBSS) plays a major role, that of chain elongation, in the biosynthesis of amylose, a starch component with mostly (1 → 4)-α connected long chains of glucose with a few (1 → 6)-α branch points. 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 … WebRequired for the synthesis of amylose (PubMed:25710501).

Web2.23.6.2 Granule-Bound Starch Synthase. GBSS is responsible for amylose biosynthesis. This group of enzymes was described by Leloir and his colleagues 42–44 and other researchers. 45,46 Waxy mutants of maize defective for GBSS contain wild-type amounts of starch with no amylose. 45 Similar waxy mutants have been obtained in other species ...
WebMar 14, 2014 · The analysis of mutants of starch synthase genes in a wide range of species demonstrates that granule-bound starch synthase I (GBSSI) is critical for amylose biosynthesis (Ball et al., 1996), but may also contribute to the synthesis of long chains of amylopectin (Maddelein et al., 1994; Denyer et al., 1996).
