Gene locations and synteny of TfKNAT genes. (A) Gene location and duplication analysis of TfKNAT genes. Red signifies a high density of genes on the chromosome; blue represents a low density of genes on the chromosome. (B) Gene locations and interchromosomal relationships of TfKNAT genes. The circos plot represents, from inside to outside, synteny relationships between chromosomes, GC content, gene density and chromosomes. The orange lines represent pairs of syntenic relationships in the class I KNOX family, the green lines indicate pairs of syntenic relationships in the class II KNOX family, and the blue lines signify pairs of syntenic relationships in the class M KNOX family
