Rice endosperm accumulates large amounts of photosynthetic products as insoluble starch
within amyloplasts by properly arranging structured, highly branched, large amylopectin …

Background Starch is the major component of cereal grains and is composed of essentially
linear amylose and highly branched amylopectin. The properties and composition of starch …

Key message High levels of two major starch synthases, SSIIa and GBSSI, in ss3a ss4b
double mutant rice alter the starch structure but fail to recover the polygonal starch granule …

Soluble starch synthases (SSs) are major enzymes involved in starch biosynthesis in
developing rice (Oryza sativa L.) endosperm. Despite extensive studies of SSs in various …

Resistant starch (RS) is beneficial to human health. In order to reduce the current
prevalence of diabetes and obesity, several transgenic and mutant crops containing high RS …

Background The genetic diversity of six starch biosynthetic genes (Wx, SSI, SSIIa, SBEI,
SBEIIa and SBEIIb) in indica and japonica rices opens an opportunity to produce a new …

Amylose and amylopectin are determinants of the physicochemical properties for starch and
grain quality in rice. Their biosynthesis is catalyzed by the interplay of ADP-glucose …

During the last couple of decades, rapid progress has been made in increasing our
understanding of the specific contributions of the most important enzymes to starch …

The Wx gene is the major gene controlling amylose synthesis in rice endosperm. So far, the
Wx gene can be mainly classified into five common alleles, wx, Wx t, Wx g1, Wx g2, and Wx …

Starch synthase (SS) I and IIIa are the first and second largest components of total soluble
SS activity, respectively, in developing japonica rice (Oryza sativa L.) endosperm. To …
