The carbohydrate-binding specificity of rice (Oryza sativa) lectin was investigated by testing the ability of radioactively labelled glycopeptides and oligosaccharides to bind to a rice lectin-Sepharose 4B column. Rice lectin binds asparagine-linked oligosaccharides through the core

Alginate oligosaccharides (AOS), which are marine oligosaccharides, are involved in regulating plant root growth, but the promotion mechanism for AOS remains unclear. Here, AOS (10-80 mg/L) induced the expression of auxin-related gene (OsYUCCA1, OsYUCCA5, OsIAA11 and OsPIN1) in rice (Oryza sativa
The crystal structure of rice (Oryza sativa L.) Os4BGlu12, an oligosaccharide and tuberonic acid glucoside-hydrolyzing β-glucosidase with significant thioglucohydrolase activity.

Cell-free extracts of UV-irradiated rice (Oryza sativa L.) leaves have a much greater capacity for the synthesis from geranylgeranyl pyrophosphate of diterpene hydrocarbons, including the putative precursors of rice phytoalexins, than extracts of unstressed leaves (KA Wickham, CA West [1992] Arch
OsMOGS is required for N-glycan formation and auxin-mediated root development in rice (Oryza sativa L.).

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

Sialic acids are widely distributed among living creatures, from bacteria to mammals, but it has been commonly accepted that they do not exist in plants. However, with the progress of genome analyses, putative gene homologs of animal sialyltransferases have been detected in the genome of some
Inhibition of gibberellin-induced elongation growth of rice by feruloyl oligosaccharides.

The biological activity of cell wall-derived feruloyl oligosaccharides was investigated using a modified micro-drop bioassay. A feruloyl arabinoxylan trisaccharide (FAXX) and a feruloyl arabinoxylan tetrasaccharide (FAXXX) were found to inhibit the gibberellin-induced elongation of dwarf rice (Oryza

The ability of seeds to withstand desiccation develops during embryogenesis and differs considerably among species. Paddy rice (Oryza sativa L.) grains readily survive dehydration to as low as 2% water content, whereas North American wild rice (Zizania palustris var interior [Fasset] Dore) grains

We identified four new family 19 chitinases in Oryza sativa L. cv. Nipponbare: one class I (OsChia1d), two class II (OsChia2a and OsChia2b), and one class IV (OsChia4a). OsChia2a resembled (about 60% identity) the catalytic domains of class I chitinases, but OsChia2b was almost identical (95%

BACKGROUND
Many plant beta-galactosidases (Bgals) have been well characterized and their deduced biological functions mainly involve degradation of structural pectins, xyloglucans or arabinogalactoproteins in plant cell walls. However, gene multiplicity in glycosyl hydrolase family 35 (GH35), to
