Gene architecture of Fe/Zn responsive genes in Phaseolus vulgaris L. The exon–intron structures of Fe/Zn responsive genes were determined by comparing the coding sequences and the corresponding genomic DNA sequences in kilobases (Kb) using the Gene Structure Display Server (GSDS). The yellow rounded rectangles indicate exons, the black lines indicate introns and the blue lines indicate upstream/downstream regions of gene.
