Data from: A FISH-based chromosome map for the European corn borer yields insights into ancient chromosomal fusions in the silkworm

Yuji Yasukochi, Mizuki Ohno, Fukashi Shibata, Akiya Jouraku, Ryo Nakano, Yukio Ishikawa & Ken Sahara
A significant feature of the genomes of Lepidoptera, butterflies and moths, is the high conservation of chromosome organization. Recent remarkable progress in genome sequencing of Lepidoptera has revealed that syntenic gene order is extensively conserved across phylogenetically distant species. The ancestral karyotype of Lepidoptera is thought to be n = 31; however, that of the most well studied moth, Bombyx mori, is n = 28, and diverse studies suggest that three chromosomal fusion events occurred...

Data from: The fate of W chromosomes in hybrids between wild silkmoths, Samia cynthia ssp.: no role in sex determination and reproduction

Atsuo Yoshido, Frantisek Marec & Ken Sahara
Moths and butterflies (Lepidoptera) have sex chromosome systems with female heterogamety (WZ/ZZ or derived variants). The maternally inherited W chromosome is known to determine female sex in the silkworm, Bombyx mori. However, little is known about the role of W chromosome in other lepidopteran species. Here we describe two forms of the W chromosome, W and neo-W, that are transmitted to both sexes in offspring of hybrids from reciprocal crosses between subspecies of wild silkmoths,...
