Breakpoints within the biggest synteny block, between L. kluyveri, L. thermotolerans, and L. waltii. This block corresponds to a 670-kb telomere-proximal region of C-left in L. kluyveri. Reciprocal best hit orthologs are linked with hatched light green parallelepipeds. (Double oblique lines) Synteny is maintained in the regions between two orthologs. Elements at synteny breakpoints such as solo LTR (black triangles) or species-specific genes (orange arrows) are represented. No LTR was found in C-left, whereas some are present in both L. thermotolerans and L. waltii regions, in particular at the breakpoint flanking the MAT locus in L. thermotolerans. While the breakpoint lies at SAKL00418g in L. kluyveri, the synteny blocks between L. thermotolerans and L. waltii extends until the HMR and HML silent cassettes, which are lost in L. kluyveri. Gene names have been abbreviated; for example, 440g on Klth0F corresponds to KLTH0F00440g.
