Figure 1From: CR1 clade of non-LTR retrotransposons from Maculinea butterflies (Lepidoptera: Lycaenidae): evidence for recent horizontal transmissionNJ phylogeny based on partial RT domain nucleotide sequences of newly isolated retrotransposons from four species of Maculinea. Statistical support was evaluated by bootstrapping (1000 replications); nodes with bootstrap values over 50% are indicated. CR1 elements can be divided into three distinct lineages: MacCR1A, MacCR1B and MacCR1C.Back to article page
