Silurana chromosomal evolution: A new piece to the puzzle
Original language description
The African clawed frogs of the subgenus Silurana comprise both diploid and tetraploid species. The root of the polyploidization event leading to the extant Xenopus calcaratus, X. mellotropicalis, and X. epitropicalis is not fully understood so far. In X. mellotropicalis, we previously proposed 2 evolutionary scenarios encompassing complete (scenario A) or incomplete (scenario B) translocation of a heterochromatic block from chromosome 9 to 2 in a diploid ancestor. To resolve this puzzle, we performed FISH coupled with tyramide signal amplification (FISH-TSA) using 5 X. tropicalis and X. mellotropicalis single copy gene probes (gyg2, cept1, fn1, ndufs1, and sf3b1) reflecting borders of the heterochromatic blocks in X. tropicalis chromosome 9 (XTR 9) and X. mellotropicalis chromosome 9b (XME 9b) and XME 2a. cDNA sequencing recognized both homoeologous genes in X. mellotropicalis. Comparison of gene physical mapping between X. tropicalis and X. mellotropicalis clearly confirmed complete rather than incomplete translocation t(9;2) of the heterochromatic block in the diploid predecessor and thus favored scenario A regarding the formation of an ancestral allotetraploid karyotype.
