A minority of angiosperms have male and female flowers separated in distinct individuals
(dioecy), and most dioecious plants do not have cytologically different (heteromorphic) sex …

Summary Butterflies (Papilionoidea), with over 18,000 described species [1], have
captivated naturalists and scientists for centuries. They play a central role in the study of …

In 2008, the genome assembly and gene models for the domestic silkworm, Bombyx mori,
were published by a Japanese and Chinese collaboration group. However, the genome …

Previous studies have reported that chromosome synteny in Lepidoptera has been well
conserved, yet the number of haploid chromosomes varies widely from 5 to 223. Here we …

Bombyx mori (silkworm) is the most famous lepidopteran in Japan. B. mori has long been
used in the silk industry and also as a model insect for agricultural research. In recent years …

I review theoretical models for the evolution of supergenes in the cases of B atesian mimicry
in butterflies, distylous plants and sex chromosomes. For each of these systems, I outline the …

We report a draft assembly of the genome of Hi5 cells from the lepidopteran insect pest,
Trichoplusia ni, assigning 90.6% of bases to one of 28 chromosomes and predicting 14,037 …

We analyzed 20 chemosensory protein (CSP) genes of the silkworm Bombyx mori. We
found a high number of retrotransposons inserted in introns. We then analyzed expression …

Diapause is a life history strategy allowing individuals to arrest development until favourable
conditions return, and it is commonly induced by shortened day length that is latitude …

Guanine-rich and cytosine-rich DNA can form four-stranded DNA secondary structures
called G-quadruplex (G4) and i-motif, respectively. These structures widely exist in genomes …
