Evolution of centromeric transposable elements in green algae. A Predominant transposable elements (TEs) in the centromeres of green algal species. Different colors represent different TE families. MRCA represents the most recent common ancestor; (B) Synteny analyses of the 13 chromosomes of Chlorella sp. SLA-04, 12 chromosomes of Chlorella sorokiniana NS4-2 and 13 chromosomes of Chlorella pyrenoidosa DBH. The corresponding syntenic regions are marked using the same color. Approximate locations of putative centromeres are indicated by ellipses. The red circles represent the collinearity of the whole chromosomes; (C) Dot plot representation of the centromeres showing the collinearity of entire chromosomes from three Chlorella species, along with their TE composition. As with panel (A), different colors represent different TE families
