Fig. 1From: Genome-wide analysis of the citrus B3 superfamily and their association with somatic embryogenesisChromosomal locations and regional duplication of citrus B3 genes. The chromosomal position of each B3 gene was mapped to the sweet orange (a) and pummelo (b) genomes. The chromosome number is indicated at the top of each chromosome. Segmentally duplicated gene pairs are linked by red dotted lines, whereas tandemly duplicated gene pairs are linked by blue dotted linesBack to article page
