| cDNA array containing 5837 rice unique genes was used to explore gene expression patterns at 4 h intervals throughout a day. It was found that there were 190 genes with diurnal changes, of which 170 genes could change in circadian manner. Analysis of those genes showed that circadian clock played a key role in coordination of many physiological processes such as glycolysis, water and mineral elements transport. By clustering diurnal change genes from cDNA data, we found 10 clusters with different expression patterns. |
