Fig. 4From: Identification and characterization of the TCA cycle genes in maizePromoter analysis of the maize TCA cycle genes. Sequences (2000 bp) upstream of the transcriptional start sites of each maize TCA gene were submitted as a promoter to PlantCARE (http://bioinformatics.psb.ugent.be/webtools/plantcare/html/) for cis-acting element analysis. Genes were clustered based on their promoter elements, and those elements appearing more than 200 times in all maize TCA gene promoters were circledBack to article page
