Proteolytic cleavage or partial degradation of proteins is one of the important post-translational modifications for various biological processes, but it is difficult to analyze. Previously, we demonstrated that some subunits of the major rice (Oryza sativa L.) seed storage protein glutelin are
Variations in endosperm polypeptides among 16 cultivars of rice were analyzed by two-dimensional gel electrophoresis. One glutelin alpha-subunit (alpha 8) with a molecular mass of 32.5 kDa was exclusively present in indica cultivars. By contrast, the glutelin alpha 3 subunit, with a molecular mass
A high-resistant starch (RS) and low-glutelin diet is beneficial for the health of patients with diabetes and kidney diseases. Rice is an important food crop worldwide. Previous studies demonstrated that downregulating the expression of rice starch branching enzyme IIb (SBEIIb) affected the
Among the mutant lines of rice that have been selected for morphological characters, one line, NM67, was found to have a low content of glutelin and a higher content of prolamine in its seed protein than other Japanese cultivars. This mutant is a semi-dwarf and partially sterile line, and its leaves
Glutelin, the major storage protein of rice seed, consists of microheterogenous subunits and partially exists in a macromolecular form that is polymerized by intersubunit disulfide bonds. In order to analyze the glutelin subunits using high-throughput CE, we first identified a sample preparation
Two semidwarfism-related proteins, SRP-1 and SRP-2, were detected as major spots in a long-culm rice cultivar, Norin 29 and its semidwarf near-isogenic line, SC-TN1, respectively, by two-dimensional gel electrophoresis (2D-PAGE). The testcross showed that SRP-1 and SRP-2 are controlled by codominant
GluA and GluB-4/5 glutelin subfamilies are mainly localized to outer region of the endosperm, particularly in its ventral side, in rice grain, but GluC is localized to throughout the endosperm. The major seed storage protein in rice (Oryza sativa) is glutelin, which forms a vacuole-derived protein
When the glutelin protein fraction of rice (Oryza sativa L.) seeds was fractionated by sodium dodecyl sulfate polyacrylamide gel electrophoresis, three size classes of proteins, 51 kilodaltons (kD), 34 to 37 kD, and 21 to 22 kD, as well as a contaminating prolamine polypeptide of 14 kD were
Variation in growth, grain size and grain storage protein content of rice (Oryza sativa L.) in response to elevated UV-B radiation under sunlight was examined in a cool rice-growing region of Miyagi Prefecture, Japan, in 1999, 2001 and 2002. Tiller number, dry mass, panicle number, grain yield and
The grassy characteristic aroma perceived in brewed sake made from low-glutelin rice (Oryza sativa L. Mizuhonoka) was examined by gas chromatography-olfactometry and gas chromatography-mass spectrometry. By comparing the odor properties and Kovats retention indices to those of standard compounds,
The shortage of strong endosperm-specific expression promoters for driving the expression of recombinant protein genes in cereal endosperm is a major limitation in obtaining the required level and pattern of expression. Six promoters of seed storage glutelin genes (GluA-1, GluA-2, GluA-3, GluB-3,
A near full-length cDNA and three genomic clones for rice (Oryza sativa L.) glutelin were isolated and studied. Based on nucleic acid sequence and Southern blot analyses, the three isolated glutelin genomic clones were representative members of three gene subfamilies each containing five to eight
RNA-binding proteins play critical roles at multiple steps during gene expression, including mRNA transport and translation. mRNA transport is particularly important in rice (Oryza sativa L.) in order to ensure the proper localization of the prolamine and glutelin seed storage proteins. However,
Saline-soluble glycinins and insoluble glutelins are the major storage proteins in soybean (Glycine max) and rice (Oryza sativa), respectively. In spite of their differences in solubility properties, both proteins are members of the 11S globulin gene family based on their similarities in primary
To obtain fundamental information for nutritional improvement of rice (Oryza sativa) seed proteins, the alpha polypeptides of the major storage protein glutelin varied over the genus Oryza were qualitatively and quantitatively characterized with unique methods. The polypeptides were maximally
