Rapid turnover of the W chromosome in geographical populations of wild silkmoths, Samia cyntia ssp

Original language description

Geographical populations of Samia cynthia ssp. differ in chromosome numbers and show derived sex chromosome systems including Z0/ZZ in S. cynthia ricini (2n=27/28), neo-Wneo-Z/neo-Zneo-Z in S. cynthia walkeri (2n=26/26) and neo-WZ1Z2/Z1Z1Z2Z2 in S. cynthia subsp. indet. (2n=25/26). We examined S. cynthia pryeri with an ancestral-like karyotype of 2n=28/28 and a WZ/ZZ sex chromosome system. The S. cynthia pryeri W chromosome was composed of a highly heterochromatic body and of a euchromatin-like tail. CGH and FISH with W chromosome painting probes revealed that the highly heterochromatic part lacks homology in the genomes of other subspecies, whereas the euchromatin-like part corresponds to a heterochromatic part of the neo-W chromosomes in S. cynthia walkeri and S. cynthia subsp. indet. Our findings suggest that the curious WZ system of S. cynthia pryeri may represent an ancestral state of the Samia species complex but do not exclude an alternative hypothesis of its derived origin.
