Název v původním jazyce

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

Popis výsledku v původním jazyce

Our previous studies revealed a considerably high level of chromosomal polymorphism in wild silkmoths, Samia cynthia ssp. (Lepidoptera: Saturniidae). Geographical populations of this species complex differ in chromosome numbers and show derived sex chromosome systems including Z0/ZZ in S. cynthia ricini (2n = 27/28; Vietnam), neo-Wneo-Z/neo-Zneo-Z in S. cynthia walkeri (2n = 26/26; Sapporo, Hokkaido) and neo-WZ(1)Z(2)/Z(1)Z(1)Z(2)Z(2) in S. cynthia subsp. indet. (2n = 25/26; Nagano, Honshu). In this study, we collected specimens of S. cynthia pryeri in Japanese islands Kyushu, Shikoku and Honshu, with an ancestral-like karyotype of 2n = 28 in both sexes and a WZ/ZZ sex chromosome system, except for one population, in which females have lost the W chromosome. However, the S. cynthia pryeri W chromosome showed a very unusual morphology: It was composed of a highly heterochromatic body, which remained condensed throughout the whole cell cycle and of a euchromatin-like "tail." We examined
