glycan/oryza sativa

N-glycosylation is a major modification of glycoproteins in eukaryotic cells. In Arabidopsis, great progress has been made in functional analysis of N-glycan production, however there are few studies in monocotyledons. Here, we characterized a rice (Oryza sativa L.) osmogs mutant with shortened

To explore the physiological significance of N-glycan maturation in the plant Golgi apparatus, gnt1, a mutant with loss of N-acetylglucosaminyltransferase I (GnTI) function, was isolated in Oryza sativa. gnt1 exhibited complete inhibition of N-glycan maturation and accumulated high-mannose

In plants, α1,3-fucosyltransferase (FucT) catalyzes the transfer of fucose from GDP-fucose to asparagine-linked GlcNAc of the N-glycan core in the medial Golgi. To explore the physiological significance of this processing, we isolated two Oryza sativa (rice) mutants (fuct-1 and fuct-2) with loss of

N-Glycosylation is one of the post-translational modifications. In animals, N-glycans linked to proteins function in cell-cell recognition, sorting, transport, and other biological phenomena. However, in plants, N-glycan-mediated biological functions remain obscure. In a previous study, we showed

Silver nanomaterials have been mainly developed as antibacterial healthcare products worldwide, because of their antibacterial activity. However, there is little data regarding the potential risks and effects of large amounts of silver nanomaterials on plants. In contrast, N-glycans play important

All fundamental information such as signal transduction, metabolic control, infection, cell-to-cell signaling, and cell differentiation related to the growth of plants are preserved in germs. In preserving these information, glycans have a key role and are involved in the development and

Cellulose synthase genes (CesAs) encode a broad range of processive glycosyltransferases that synthesize (1-->4)beta-D-glycosyl units. The proteins predicted to be encoded by these genes contain up to eight membrane-spanning domains and four 'U-motifs' with conserved aspartate residues and a QxxRW

We report the cloning of a glycoside hydrolase family (GHF) 9 gene of rice (Oryza sativa L. cv. Sasanishiki), OsCel9A, corresponding to the auxin-induced 51 kDa endo-1,4-beta-glucanase (EGase). This enzyme reveals a broad substrate specificity with respect to sugar backbones (glucose and xylose) in

Seed germination rates and plant development and growth under abiotic stress are important aspects of crop productivity. Here, our characterization of the rice (Oryza sativa L.) mutant reduced culm number11 (rcn11) showed that RCN11 controls growth of plants exposed to abnormal temperature, salinity

Human alpha-antitrypsin (AAT) is the most abundant circulating protease inhibitor in the human plasma. It is produced in the liver and exerts a primary physiological role as inhibitor for the neutrophil elastase in the lung. Individuals with one or several gene mutations in AAT causing reduction of

Molecular cloning of the "old" but still unclassified Euonymus europaeus agglutinin (EEA) demonstrated that the lectin is a homodimeric protein composed of 152 residue subunits. Analysis of the deduced sequence indicated that EEA is synthesized without a signal peptide and undergoes no

In the root of rice (Oryza sativa), abscisic acid (ABA) treatment, salinity, or water deficit stress induces the expression of a family of four genes, REPETITIVE PROLINE-RICH PROTEIN (RePRP). These genes encode two subclasses of novel proline-rich glycoproteins with highly repetitive PX₁PX₂ motifs,

The seed storage protein [beta]-phaseolin of the common bean (Phaseolus vulgaris L.) was expressed in the endosperm of transgenic rice (Oryza sativa L.) plants. The 5.1- or 1.8-kb promoter fragment of the rice seed storage protein glutelin Gt1 gene was fused transcriptionally to either the genomic
