pyridine/oryza sativa

As part of our studies on the physiological and ecological function of caffeine, we investigated the effect of exogenously supplied caffeine on purine, pyrimidine and pyridine metabolism in rice seedlings. We examined the effect of 1 mM caffeine on the in situ metabolism of 14C-labelled adenine,

Rice (Oryza sativa) glutamate synthase (GOGAT, EC 1.4.1.14) enzymes have been proposed to have great potential for improving nitrogen use efficiency, but their functions in vivo and their effects on carbon and nitrogen metabolism have not been systematically explored. In this research, we analyzed

BACKGROUND To increase rice production in Africa, considerable research has focused on creating interspecific hybrids between African (Oryza glaberrima Steud.) and Asian (O. sativa L.) rice in an attempt to obtain the positive attributes of each in new cultivars. Since flavor is a key criterion in

The aroma of rice essentially contributes to the quality of rice grains. For some varieties, their aroma properties really drive consumer preferences. In this paper, using a dynamic headspace solid-phase microextraction (HS-SPME) system coupled to a two-dimensional gas chromatography (GC×GC) using a

Ferredoxin-dependent glutamate synthase (EC 1.4.7.1) from rice leaves (Oryza sativa L. cv Delta) was purified 206-fold with a final specific activity of 35.9 mumoles glutamate formed per min per milligram protein by a procedure including ammonium sulfate fractionation, DEAE-cellulose chromatography,

Metabolism of [carbonyl-14C]nicotinamide was surveyed in various plant materials including the model plants, Arabidopsis thaliana, Oryza sativa and Lotus japonicus. In all plants studied, nicotinamide was used for the pyridine (nicotinamide adenine) nucleotide synthesis, probably after conversion to

The majority of plant species accumulate high intracellular levels of proline to cope with hyperosmotic stress conditions. Proline synthesis from glutamate is tightly regulated at both the transcriptional and the translational levels, yet little is known about the mechanisms for post-translational
