Fig. 3From: Comparative analysis of cytokinin response factors in Brassica diploids and amphidiploids and insights into the evolution of Brassica speciesChromosomal mapping of CRFs in B. rapa, B. oleracea, and B. napus.. The CRFs in B. rapa (a), B. oleracea (b), and B. napus (c) are shown except those located on the scaffolds. The locations were shown on the left of the chromosomes, whereas the gene names were on the right. The arrows next to gene names show the direction of transcription.
