Fig. 2From: Exon-intron structure and sequence variation of the calreticulin gene among Rhipicephalus sanguineus group ticksAlignment of crt exon-intron region in Rhipicephalus spp. individuals analysed (codes as in Table 1). Nucleotides in orange boxes belong to exon regions in 5′ and 3′ splice donor regions. Nucleotides in light grey boxes belong to intron region in 5′ and 3′ splice donor regions. Nucleotides in black boxes indicate sequence identity in intron region. Asterisks show nucleotide identity in exon regions. Numbers indicate the nucleotide position of the R. sanguineus (s.l.) crt sequence AY395275.1 [25]. Abbreviations: R.s. Trop. lin., Rhipicephalus sanguineus (s.l.) “Tropical lineage”; R.s. Temp. lin., Rhipicephalus sanguineus (s.l.) “Temperate lineage”Back to article page
