TTAGG Telomeric Repeats in Chromosomes of Some Insects and Other Arthropods
We studied the occurrence of the TTAGG telomere repeats by fluorescence in-situ hybridization (FISH) and Southern hybridization in ten insect species and two other arthropods. (TTAGG)n-containingExpand
Sex Chromosomes and Sex Determination in Lepidoptera
The speciose insect order Lepidoptera (moths and butterflies) and their closest relatives, Trichoptera (caddis flies), share a female-heterogametic sex chromosome system. Originally a Z/ZZExpand
Evolutionary dynamics of rDNA clusters on chromosomes of moths and butterflies (Lepidoptera)
We examined chromosomal distribution of major ribosomal DNAs (rDNAs), clustered in the nucleolar organizer regions (NORs), in 18 species of moths and butterflies using fluorescence in situExpand
Analysis of genetic information of an insect picorna-like virus, infectious flacherie virus of silkworm: evidence for evolutionary relationships among insect, mammalian and plant picorna(-like)
SummaryWe synthesized the cDNAs of an insect picornavirus, infectious flacherie virus of silkworm (IFV), genomic RNA and inserted it into a bacterial plasmid (pUC119). The 9 650 nucleotides (nts)Expand
Phenotypic grouping of 141 BmNPVs lacking viral gene sequences.
We constructed a series of gene knockout BmNPVs (KOVs) for each of 141 genes (Gomi et al., 1999; Katsuma et al., 2011) using the BmNPV T3 bacmid system (Ono et al., 2007) and lambda red recombinationExpand
Phylogeny of the sex-determining gene Sex-lethal in insects.
The Sex-lethal (SXL) protein belongs to the family of RNA-binding proteins and is involved in the regulation of pre-mRNA splicing. SXL has undergone an obvious change of function during the evolutionExpand
A Second-Generation Integrated Map of the Silkworm Reveals Synteny and Conserved Gene Order Between Lepidopteran Insects
A second-generation linkage map was constructed for the silkworm, Bombyx mori, focusing on mapping Bombyx sequences appearing in public nucleotide databases and bacterial artificial chromosome (BAC)Expand
W-derived BAC probes as a new tool for identification of the W chromosome and its aberrations in Bombyx mori
We isolated four W chromosome-derived bacterial artificial chromosome (W-BAC) clones from Bombyx mori BAC libraries by the polymerase chain reaction and used them as probes for fluorescence in situExpand
Organization of the Hox gene cluster of the silkworm, Bombyx mori: a split of the Hox cluster in a non-Drosophila insect
A bacterial artificial chromosome (BAC) contig was constructed by chromosome walking, starting from the Hox genes of the silkworm, Bombyx mori. Bombyx orthologues of the labial (lab) and zerknültExpand
Sex chromosome evolution in moths and butterflies
Lepidoptera, i.e. moths and butterflies, have a female heterogametic sex chromosome system, with most females having a WZ constitution while males are ZZ. Besides this predominant WZ/ZZ system, Z/ZZ,Expand
