An important and interesting feature of rice is that it can germinate under anoxic conditions. Though several biochemical adaptive mechanisms play an important role in anaerobic germination of rice but the role of phytoglobin-nitric oxide cycle and ...

Lipid biochemistry of echinochloa crus-galli during anaerobic germination
Phytochemistry, 1984Abstract Seven day old seedlings of Echinochloa crus-galli var. oryzicola (Vasing) had a higher total lipid content when germinated under N 2 than in air, although ungerminated seeds contained more lipid than either seedling. The triacylglycerol pool was not depleted under anaerobiosis as it was in air and only air-grown seedlings showed a net ...

Genetic variability for and tolerance to anaerobic germination in rice (Oryza sativa L.)
Journal of Crop Improvement, 2021Poor germination and seedling establishment under flooded conditions is a major bottleneck in the direct-seeding system of rice. The objectives of this study were to determine the genetic variability for traits associated with anaerobic germination and ...

A trehalose-6-phosphate phosphatase enhances anaerobic germination tolerance in rice
Nature Plants, 2015Global socioeconomic developments create strong incentives for farmers to shift from transplanted to direct-seeded rice (DSR) as a means of intensification and economization(1). Rice production must increase to ensure food security(2) and the bulk of this increase will have to be achieved through intensification of cultivation, because expansion of ...

Effect of nitrous oxide on anaerobically-germinated rice seedlings
Plant Science Letters, 1978Abstract Rice seedlings germinated in anaerobic environments consisting of nitrous oxide and nitrogen gases, respectively, manifested the d − (anaerobic) type of seedling germination consisting of coleoptilar extension growth only. Nitrous oxide adversely affected the fermentative growth processes in the germinating seedlings since the extent of ...

Expression of glutamine synthetase during the anaerobic germination of Oryza sativa L.
Planta, 1994Glutamine synthetase (GS; EC.6.3.1.2.) occurs as cytosolic (GS1) and plastidic (GS2) polypeptides. This paper describes the expression of GS isoenzymes in coleoptile during the anaerobic germination of rice (Oryza sativa L.) and the influence of exogenous nitrate on this.

Preliminary Evidence of Nitrate Assimilation during the Anaerobic Germination of Rice
1993The utilisation of nitrate stored in the seed was studied during the anaerobic germination of rice (Oryza sativa L.). After 11 days of germination, 74% of the initial nitrate content had been utilised. At all times during anaerobic germination, nitrate reductase and nitrite reductase activities were undetectable in the caryopsis, but present in the ...

Mitochondrial enzymes in aerobically and anaerobically germinated seedlings of Echinochloa and rice
Planta, 1991Activities of tricarboxylic acid (TCA) cycle enzymes in seedlings of barnyard grass (Echinochloa phyllopogon (Stapf.) Koss) and rice (Oryza sativa L.) germinated under aerobic and anaerobic conditions were investigated. In E. phyllopogon, development of TCA-cycle enzyme activities during 10 d of anoxia generally paralleled those in air, although at ...

Respiratory activity in rice seedlings germinated under strictly anaerobic conditions
The Botanical Magazine Tokyo, 1972Rice seedlings germinated for up to 96 hr from the imbibition under strictly anaerobic conditions had a certain level of respiratory activity, though less than that of aerobic controls. Nitro-BT positive particles were recognized in coleoptile cells of these seedlings.

Germination and outgrowth of single spores of Clostridium botulinum and putrefactive anaerobes
Journal of Applied Bacteriology, 1982Abstract Single spores of putrefactive anaerobes (PAs) germinated more slowly than those of Clostridium botulinum types A & B, with calculated times for 10% germination from 2 to 302 d. If PA spores were used in inoculated pack studies to simulate the response of
