Genomic organization (synteny) of B_sister genes in core eudicots. ABS- (A) and GOA-like genes (B) are boxed. Genes surrounding B_sister genes and their orientation are indicated by pentagons. Putative orthologs among the surrounding genes which are present in more than two species are shown in identical color and with identical label. The annotation of these genes according to the euKaryotic Orthologous Groups (KOG, identifier given in brackets) or the function as annotated in Phytozome is given at the bottom. For Brassicaceae species in which more than one ABS- or GOA-like gene is present, one gene was chosen arbitrarily. The end of a scaffold is marked by a vertical line. The GOA-like gene and the neighboring 3′ gene in Eutrema salsugineum have been lost. Genomic loci of B_sister genes of Brassicaceae species are highlighted in gray. Abbreviations: Chr, chromosome; Sca, scaffold; SuCo, supercontig; Lg, linkage group.
