The components of the volatile oils from the straws of Oryza sativa L. (Onshinomai, Asamurasaki, Hinohikari) were analyzed by capillary GC/GC-MS. The quantification of volatile compounds in the oils was made by the internal standard method, using palmitic acid as reference substance. Palmitic acid
α-Dioxygenases (α-DOX) are heme-containing enzymes found predominantly in plants and fungi, where they generate oxylipins in response to pathogen attack. α-DOX oxygenate a variety of 14-20 carbon fatty acids containing up to three unsaturated bonds through stereoselective removal of the pro-R
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).
Inappropriate application of pesticide often triggers molecular alterations in crops, which inadvertently disturbs metabolites and finally affects crop quality. Therefore, understanding the mechanism of action of pesticides on crops is essential for evaluating the potential environmental impact of
The present study reports the composition and variation of fatty acids, sterols, tocopherols and γ-oryzanol among selected varieties namely Basmati Super, Basmati 515, Basmati 198, Basmati 385, Basmati 2000, Basmati 370, Basmati Pak, KSK-139, KS-282 and Irri-6 of Pakistani rice (Oryza sativa L). Oil
Plants have the natural ability to withstand stress conditions through metabolic adjustments. The present study aimed at investigating the effects of titanium dioxide nanoparticles (TiO2 NPs) application (0, 25, 50, 150, 250, 500, and 750 mg kg-1) in phosphorus-deficient soil in terms of growth
Coconut (Cocos nucifera L.) is a key tropical crop and a member of the monocotyledonous family Arecaceae (Palmaceae). Few genes and related metabolic processes involved in coconut endosperm development have been investigated. In this study, a new member of the WRI1 gene family was isolated from
An adequate supply of mineral nutrients is crucial to obtain optimum productivity in agriculture. The present investigation was carried to find the inoculation effect of plant growth-promoting rhizobacteria (PGPR), i.e., Paenibacillus lentimorbus B-30488 (B-30488), Bacillus amyloliquefaciens SN13
Phytohormones and fatty acids (FAs) play important roles in plant resistance to insects and pathogens. In this study, we investigated the similarities and differences in the accumulations of phytohormones and FAs in the resistant wheat (Triticum aestivum L.) 'Molly' and the nonhost rice (Oryza
Submergence induces rapid elongation of deepwater rice (Oryza sativa L.) internodes. This adaptive feature allows deepwater rice to grow out of the water and to survive flooding. The growth response of submerged deepwater rice plants is, ultimately, elicited by gibberellin (GA). Little attention has
Substrate selectivity of glycerol-3-phosphate acyltransferase (EC 2. 3. 1. 15) of rice (Oryza sativa L.) was explored in a comparative study of acyltransferases from seven plant species. In vitro labeling of acyl carrier protein (ACP) with (14)C or (3)H showed that acyltransferase from
Long-chain fatty acids can be metabolized to C(n)(-1) aldehydes by alpha-oxidation in plants. The reaction mechanism of the enzyme has not been elucidated. In this study, a complete nucleotide sequence of fatty acid alpha-oxygenase gene in rice plants (Oryza sativa) was isolated. The deduced amino
The grain size and shape of rice are limited by the growth of the spikelet hulls and are important selective target during domestication and breeding. In this study, we identified a glycine- and proline-rich protein (OsGPRP3), which belongs to a conserved family rarely studied. We found that
The composition of rice (Oryza sativa L.) grain fatty acids (18% palmitic acid, 36% oleic acid and 37% linoleic acid) is suboptimal for rice storage and utilisation of rice bran oil as food grade oil or a source of biodiesel. Genetic manipulation of fatty acid composition in rice bran oil to
