In silico analysis of motifs in promoters of differentially expressed genes in rice (Oryza sativa L.) under anoxia
The aim of this study was to characterise the molecular mechanisms of transcriptional regulation of Differentially Expressed Genes (DEGs) in rice coleoptiles under anoxia by identifying motifs that are common in the promoter region of co-regulated genes. Un-changed DEGs (<2 fold and >-2), up-r...

Summary: | The aim of this study was to characterise the molecular mechanisms of transcriptional regulation of Differentially Expressed Genes (DEGs) in rice coleoptiles under anoxia by identifying motifs that are common in the promoter region of co-regulated genes. Un-changed DEGs (<2 fold and >-2), up-regulated DEGs (>or=2 fold) and down-regulated DEGs (<or=-2 fold) were separated in three different data sets. Their gene promoters were extracted from eukaryotic promoter database. Statistically significant consensus promoter motifs were detected by in silico method. A significant variation in the number of promoter motifs, consensus promoter motif and their sequences between UR-DEGs and DR-DEGs were detected that might be responsible for their related expression. |
