Polysaccharide-linked hydroxycinnamoyl esters (PHEs) over-accumulate in the internodes of a rice (Oryza sativa L.) mutant, Fukei 71 (F71). This accumulation is accompanied by over-expression of phenylalanine ammonialyase (PAL). In this study, we show that only one member of the
Rice (Oryza sativa L.) is a salt-sensitive crop which could be suppressed seriously by salt stress at germination stage. Some seaweeds polysaccharides could enhance plants resistance but there is little research about polysaccharides from Grateloupia filicina in agriculture. Therefore, G. filicina
In order to improve the bioavailability of Oryza sativa L. anthocyanins, we fabricated Oryza sativa L. anthocyanins-Hohenbuehelia serotina polysaccharides (OSA-HSP) complex and investigated its anti-proliferation activities taking into account its changes along simulated gastrointestinal digestion
Multispectral analysis combined with the Periodic Acid-Schiff method was used to investigate cytological features of insoluble polysaccharides and changes in total insoluble polysaccharide content (TPC) during pollen development in rice, including four cytoplasmic male sterility lines (MSLs) and
Purple glutinous rice bran (Kum Doi Saket rice (KUM)) contains high content of edible polysaccharides and anthocyanins and has an excellent antioxidant activity. This research aimed to optimize the extraction of crude polysaccharides from defatted purple glutinous rice bran using an
The present study was conducted to investigate the mechanism inducing the difference in the cell wall extensibility of rice (Oryza sativa L. cv. Koshihikari) coleoptiles grown under various temperature (10-50 degrees C) conditions. The growth rate and the cell wall extensibility of rice coleoptiles
We examined a novel rice mutant, Fukei 71 (Oryza sativa L.), for alterations in the levels of hydroxycinnamoyl esters that are linked to cell wall polysaccharides and lignin units. In this mutant, a recessive mutation at a single locus caused the collapse of parenchyma cells in the internodes. Light
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

Our study demonstrated that Zn alleviated Cd toxicity in the presence of Si in the cell walls by Zn 2+ binding to ligands through the formation of the [Si-hemicellulose matrix]Zn complexes that restrict the uptake of Cd. The plant cell wall exhibits preferential sites for the accumulation
The combined effects of lucerne (Medicago sativa L.) extract supplementation and ammonia treatment of rice straw (Oryza sativa, variety Thaibonnet) on the ruminal digestion of cell wall components were investigated in six continuous culture systems using a randomised complete block design. Data were
Microscopic examination of suspension- cultured cells of Phleum pratense L., Panicum miliaceum L., Phalarisaquatica L. and Oryza sativa L. showed that they were comprised of numerous root primordia. Polysaccharides secreted by these suspension cultures contained glycosyl linkages consistent with the
Both polysaccharide-linked hydroxycinnamoyl esters (PHEs) and lignin are biosynthesized via the phenylpropanoid pathway. In the abnormal internode parenchyma of the rice (Oryza sativa L.) mutant Fukei 71, which has a defective recessive gene (d50), the biosynthesis of lignin and PHEs differs. . The
Poales [represented by rice (Oryza sativa L.)] in angiosperms and Equisetum (horsetails) in Pteridophytes are two major groups of heavy silicon (Si) accumulators. In rice, Si is polymerized preferentially in the epidermal cell wall, forming Si-cuticle double layers and Si-cellulose double layers
l-Arabinose is one of the main constituents of cell wall polysaccharides such as pectic rhamnogalacturonan I (RG-I), glucuronoarabinoxylans and other glycoproteins. It is found predominantly in the furanose form rather than in the thermodynamically more stable pyranose form. UDP-L-arabinofuranose
Lignin encrusts lignocellulose polysaccharides, and has long been considered an obstacle for the efficient use of polysaccharides during processes such as pulping and bioethanol fermentation. However, lignin is also a potential feedstock for aromatic products and is an important by-product of
