Distribution of differentially expressed transcripts in chromosomes 5, 16, 30 and 36 of Leishmania major and Leishmania infantum . On the horizontal axis are all genes in the order found on the selected chromosomes according to GeneDB . On the vertical axis is the amastigote (Ama) to promastigote (Pro) expression ratio. Genes upregulated in the amastigote stage are above the line at 0.75 and genes upregulated in promastigotes are below the line -0.75. Blue dots represent stage-regulated expression of genes on the respective L. infantum chromosomes and black dots represent differential expression of genes on the same chromosomes of L. major.
