Fig. 4From: A genome-wide analysis of the small auxin-up RNA (SAUR) gene family in cottonPhylogenetic relationships, gene structure and motif compositions of the Gossypium raimondii SAUR genes. a The phylogenetic tree was constructed using MEGA 6.0 with the Neighbour-Joining (NJ) method with 1000 bootstrap replicates. b Exon/intron structures of SAUR genes from G. raimondii. The introns, CDS and UTRs are represented by black lines, green and blue boxes respectively. The scale bar represents 0.5Â kb. c Protein motif. Each motif is represented in the colored boxBack to article page
