Regulation of growth in rice seedlings
Journal of Plant Growth Regulation, 1983Etiolated rice seedlings (Oryza sativa L.) exhibited marked morphological differences when grown in sealed containers or in containers through which air was passed continuously. Enhancement of coleoptile and mesocotyl growth and inhibition of leaf and root growth in the sealed containers (“enclosure syndrome”) were accompanied by accumulation of CO2 ...

Variation in the nitrate reductase of rice seedlings
Planta, 1972Nitrate reductase was induced in rice seedlings by nitrate and by chloramphenicol. During the induction period the different enzyme activities associated with nitrate reductase increased to different degrees. Nitrate induced high NADH-nitrate reductase activity and a great increase in the NADH-cytochrome c reductase activity which was associated with ...

Dissemination of weeds with rice seedlings
Tropical Pest Management, 1988Abstract Dissemination of weed seeds, weed seedlings, and shoots of perennial weeds along with transplanted rice (Oryza sativa L.) seedlings was observed in farmers’ fields in Guimba, Nueva Ecija, Philippines. The percentage of weed seedlings and shoots in bundles of rice seedlings to be transplanted into the field ranged from 4–5 to 14.2% in the wet ...

Agmatine deiminase in rice seedlings
Phytochemistry, 1985Abstract Agmatine deiminase activity in rice embryos increased gradually upto 24 hr during germination and then decreased. Gibberellic acid and kinetin inhibited the activity when added to the germination medium. The enzyme was purified 717 fold with specific activity 788.5 nkat/mg protein and yield 8.8%.

Phasic Development of Rice Seedlings
Agronomy Journal, 1997AbstractA better understanding of growth and developmental processes of rice (Oryza sativa L.) seedlings is necessary for crop management and modeling perspectives. This experiment was conducted to identify preautotrophic phases of rice seedlings, quantify seed dry matter mobilization and utilization, characterize dry matter partitioning during early ...

Metabolism of Glycine in Roots of Wheat and Rice Seedlings
Journal of Plant Physiology, 1984Wheat and rice roots have been shown to decarboxylate both the carbon atoms of glycine. Cold formate and serine significantly depressed (14)CO(2) evolution from (2-(14)CO) glycine. It is therefore likely that C(1)-tetrahydrofolate pool is involved in 2-C-glycine metabolism.

Proteomic identification of rhythmic proteins in rice seedlings
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2011Many aspects of plant metabolism that are involved in plant growth and development are influenced by light-regulated diurnal rhythms as well as endogenous clock-regulated circadian rhythms. To identify the rhythmic proteins in rice, periodically grown (12h light/12h dark cycle) seedlings were harvested for three days at six-hour intervals.

Enantioselective Separation and Phytotoxicity on Rice Seedlings of Paclobutrazol
Journal of Agricultural and Food Chemistry, 2011The environmental significance of enantioselectivity in chiral insecticides and herbicides has been widely studied. However, little information is currently available on the enantioselective behavior of chiral plant growth regulators. In this study, paclobutrazol enantiomers were resolved and prepared by chiral high-performance liquid chromatography ...

Rice BIG gene is required for seedling viability
Journal of Plant Physiology, 2019Arabidopsis BIG (AtBIG) gene encodes an enormous protein that is required for auxin transport. Loss of AtBIG function not only profoundly changes plant architecture but also alters plant adaptability to environmental stimuli. A putative homolog of AtBIG exists in the rice genome, but no function has been ascribed to it.

Rice seedlings release momilactone B into the environment
Phytochemistry, 2003Since the growth inhibitor momilactone B was found recently in root exudates of rice (Oryza sativa L.), 3-day-old rice seedlings were transferred to hydroponic culture and the level of momilactone B released into the environment from the seedlings was measured.
