--We used DNA-DNA hybridization to determine large-scale phylogenetic structure among hummingbirds (Trochilidae). Analyses of complete matrices of ATto and ATmoa, statistics among eight hummingbird genera and a swift generated the same fully resolved topology, which bootstrapping and jackknifing analyses supported at the 100% level. The data are consistent with monophyly for the traditional her...

In order to establish the most sensitive and specific method in the detection of Rickettsia tsutsugamushi in Leptotrombidium deliense , mice and patients, a comparative study on DNA extraction, PCR, hybridization and PCR-hybridization was conducted. The results showed that the sensitivity of PCR-hybridization was 10 times higher than that of PCR and 1000 times higher than that of hybridization....

MOTIVATION It is widely recognized that the hybridization process is prone to errors and that the future of DNA sequencing by hybridization is predicated on the ability to successfully cope with such errors. However, the occurrence of hybridization errors results in the computational difficulty of the reconstruction of DNA sequencing by hybridization. The reconstruction problem of DNA sequencin...

Hybridization-based assays for the detection of nucleic acids including in situ hybridization are increasingly being utilized in a wide variety of disciplines such as cytogenetics, microbiology, and histology. Generally in situ hybridization assays utilize either cloned genomic probes for the detection of DNA sequences or oligonucleotide probes for the detection of DNA or RNA sequences. Alterna...

RNA sequence relatedness among avian RNA tumor virus genomes was analyzed by inhibition of DNA-RNA hybrid formation between 3H-labeled 35S viral RNA and an excess of leukemic or normal chicken cell DNA with increasing concentrations of unlabeled 35S viral RNA. The avian viruses tested were Rous associated virus (RAV)-3, avian myeloblastosis virus (AMV), RAV-60, RAV-61, and B-77 sarcoma virus. H...

--The phylogeny of the subfamily Hirundininae was estimated by hybridizing single-copy nuclear DNAs of 21 swallow species, representing 19 former and current genera, and a Tufted Titmouse (Parus bicolor) as outgroup. The phylogeny, which was unusually well resolved, consisted of three fundamental clades: Hirundo and allies, core martins, and African sawwings. The clade of Hirundo and allies com...
