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
In vitro cleavage and joining at the viral origin of replication by the replication initiator protein of tomato yellow leaf curl virus.
Replication of the single-stranded DNA genome of geminiviruses occurs via a double-stranded intermediate that is subsequently used as a template for rolling-circle replication of the viral strand.Expand
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
The telomere repeat motif of basal Metazoa
In most eukaryotes the telomeres consist of short DNA tandem repeats and associated proteins. Telomeric repeats are added to the chromosome ends by telomerase, a specialized reverse transcriptase. WeExpand
Meiotic chromosomes and stages of sex chromosome evolution in fish: zebrafish, platyfish and guppy
We describe SC complements and results from comparative genomic hybridization (CGH) on mitotic and meiotic chromosomes of the zebrafish Danio rerio, the platyfish Xiphophorus maculatus and the guppyExpand
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
Sex Chromatin in Lepidoptera
Like mammals, Lepidoptera possess female-specific sex chromatin. In a compilation of new and published data, 81% 238 investigated Lepidoptera species display one or more heterochromatin bodies inExpand

  • 19 November 1976
Pachytene preparations of the chromosome complement of female larvae of Bombyx mori were improved to give a distinct chromomere pattern of the bivalents suitable for chromosome mapping. Six of the 28Expand
The evolutionary origin of insect telomeric repeats, (TTAGG)n
RNA polymerase II is responsible for transcription of most eukaryotic genes, but, despite exhaustive analysis, little is known about how it transcribes natural templates in vivo. We studiedExpand
The sex-determining gene doublesex in the fly Megaselia scalaris: conserved structure and sex-specific splicing.
The well-known sex-determining cascade of Drosophila melanogaster serves as a paradigm for the pathway to sexual development in insects. But the primary sex-determining signal and the subsequentExpand
