Fig. 4From: Genome-wide and comparative phylogenetic analysis of senescence-associated NAC transcription factors in sunflower (Helianthus annuus)Regulatory sequences in each Orthologous Group (OG). Mean number of times that a certain TFBS appeared in the sequence of each gene was calculated for the analysis. A total of 2000 bp upstream of ATG was evaluated for a different Transcription Factor Binding Site (TFBS) in each OGBack to article page
