phospholipid/oryza sativa

Phospholipid hydroperoxide glutathione peroxidase (PHGPx) is an unique antioxidant enzyme that directly reduces lipid hydroperoxides in biomembranes. In the present work, the entire encoding region for Oryza sativa PHGPx was expressed in Escherichia coli M15, and the purified fusion protein showed a

A membrane-bound inositol phospholipid-specific phospholipase C was solubilized from rice (Oryza sativa L.) microsomal membranes and purified to apparent homogeneity using a series of chromatographic separations. The apparent molecular mass of the enzyme was estimated by sodium dodecyl

The activation of H(+)-ATPase solubilized from plasma membrane of rice (Oryza sativa L. var Nipponbare) culture cells was examined by the exogenous addition of various phospholipids, free fatty acids, glycerides, polar head groups of phospholipids and molecular species of phosphatidylcholine (PC).

With a specific focus on rice self-defense response(s), the effects of global signaling molecules, jasmonic acid (JA), salicylic acid (SA), abscisic acid (ABA), and ethylene (using the ethylene generator, ethephon), and protein phosphatase (PP) inhibitors, cantharidin and endothall on expression of

A cDNA encoding putative phospholipid hydroperoxide glutathione peroxidase (PHGPX) was isolated from rice using rapid amplification of cDNA ends. This cDNA, designated ricPHGPX, includes an open reading frame encoding a protein of 169 amino acids which shares about 60% and 50% amino acid sequence

Rice grain metabolites are important for better understanding of the plant physiology of various rice cultivars and thus for developing rice cultivars aimed at providing diverse processed products. However, the variation of global metabolites in rice grains has rarely been explored. Here, we report

Glycolipids, phospholipids, and neutral lipids were extracted from the tonoplast fraction of cultured rice cells (Oryza sativa L. var. Boro). Acyl steryl glucoside (ASG) and glucocerebroside (GlcCer) were also prepared from this fraction. We determined the effects of these tonoplast lipids on the

Nonspecific lipid transfer proteins (nsLTPs) facilitate the transfer of phospholipids, glycolipids, fatty acids and steroids between membranes, with wide-ranging binding affinities. Three crystal structures of rice nsLTP1 from Oryza sativa, complexed with myristic (MYR), palmitic (PAL) or stearic

Biophotons are ultraweak light emissions from biochemical reactions in a living body. They increase in suspension-cultured rice (Oryza sativa L.) cells when elicited by N-acetylchitooligosaccharide. Biochemical analyses were undertaken to investigate the relationship between disease response and

Several studies have shown that differences in lipid composition and in the lipid biosynthetic pathway affect the aluminium (Al) tolerance of plants, but little is known about the molecular mechanisms underlying these differences. Phospholipids create a negative charge at the surface of the plasma

An endophytic actinomycete, strain R10-82(T), isolated from surface-sterilized roots of rice (Oryza sativa L.) was studied using a polyphasic approach. Strain R10-82(T) produced branching substrate mycelia and developed spherical spore vesicles on aerial hyphae containing non-motile spores. The

An actinobacterial strain, DCWR9-8-2(T), was isolated from a leaf of Thai upland rice (Oryza sativa) collected in Chumporn province, Thailand. Strain DCWR9-8-2(T) is Gram-stain-positive aerobic bacteria that produce single spores directly on the vegetative hypha. Cell wall peptidoglycan of this

A novel endophytic actinomycete, designated strain RS15-1S^T, was isolated from surface-sterilized stems of Oryza sativa L. collected from Sisaket province, Thailand. The colony of strain was strong orange, catalase-positive and oxidase-negative. Growth occurred at a temperature range of

The negative charge at the root surface is mainly derived from the phosphate group of phospholipids in plasma membranes (PMs) and the carboxyl group of pectins in cell walls, which are usually neutralized by calcium (Ca) ions contributing to maintain the root integrity. The major toxic effect of

A Gram-stain-negative, aerobic, pale orange, rod-shaped, non-motile bacterial strain, designated JC289T was isolated from a rhizosphere soil sample of the plant Oryza sativa (L.). 16S rRNA gene sequence analysis clearly allocated strain JC289T to the Flectobacillus cluster, showing highest sequence
