Expression of genes encoding enzymes involved in specialized metabolic pathways is assumed to be regulated coordinately to maintain homeostasis in plant cells. We analyzed transcript levels of rice (Oryza sativa L.) genes associated with glycolysis and alcohol fermentation under submergence stress. When each transcript was quantified at several times, two types (I and II) of mRNA accumulation were observed in response to submergence stress. Transcripts of type I genes reached a maximum after 24 h of submergence and were reduced by transfer to aerobic conditions or by partial exposure of shoot tips to air. In a submergence-tolerant rice cultivar, transcript amounts of several type I genes, such as glucose phosphate isomerase, phosphofructokinase, glyceraldehyde phosphate dehydrogenase, and enolase, increased significantly compared to an intolerant cultivar after 24 h of submergence. This suggests that the mRNA accumulation of type I genes increases in response to anaerobic stress. mRNA accumulation of type II genes, such as aldolase and pyruvate kinase, reached a maximum after 10 h of submergence. Following transfer to aerobic conditions, their transcript levels were not so rapidly decreased as were type I genes. These results suggest that the mRNA levels of genes engaged in glycolysis and alcohol fermentation may be regulated differentially under submergence stress
