Figure 4.

Synteny analysis of heavy-metal-associated genes between Arabidopsis thaliana and Brassica rapa, Cucumis sativus, Glycine max, Gossypium raimondii, and Solanum tuberosum. Gray lines in the background indicate the collinear blocks within rice and other plant genomes, while the blue lines highlight the syntenic AtHMP gene pairs. The species names with the prefixes “A. thaliana,” “B. rapa,” “C. sativus,” “G. max,” “G. raimondii,” and “S. tuberosum” indicate Arabidopsis thaliana and Brassica rapa, Cucumis sativus, Glycine max, Gossypium raimondii, and Solanum tuberosum, respectively. Different color bars represent the chromosomes of different species. The chromosome number is labeled at the top or bottom of each chromosome.
