Tandem Quadruplication of HMA4 in the Zinc (Zn) and Cadmium (Cd) Hyperaccumulator Noccaea caerulescens
Figure 3
Genomic organisation of HMA4 in N. caerulescens.
Five overlapping genomic fosmids (horizontal blue lines) represented a 101,480 bp single locus of N. caerulescens. Genes and their transcriptional direction are represented by arrows and given A. thaliana Genome Identifier appellations (brown arrows, genes syntenic with A. thaliana HMA4 flanking regions; orange, quadruplicated NcHMA4 genes). Restriction endonuclease site locations used for fosmid fingerprinting are indicated in red; HindIII, green; BamHI, and teal; EcoRI. Numbers in brackets refer to genomic locations in base pairs.
