A program is described which aligns pairs of linear restriction site maps using an algorithm which maximizes the number of coincident sites through the addition of extra 'padding' fragments; and makes maps of the non-conserved sites between pairs and triplets of input maps. A range of display facilities, hardcopy functions and database management routines are also included. The program runs on ...

At the ade6 locus of Schizosaccharomyces pombe flanking markers have been introduced as well as five silent restriction site polymorphisms: four in the 5' upstream region and one in the middle of the gene. The mutations ade6-706, ade6-M26 (both at the 5' end) and ade6-51 (middle of the gene) were used as partners for crosses with the 3' mutation ade6-469. From these three types of crosses, wild...

The effects of Quaternary climatic oscillations on the demography of organisms vary across regions and continents. In taxa distributed in Europe and North America, several paradigms regarding the distribution of refugia have been identified. By contrast, less is known about the processes that shaped the species' spatial genetic structure in areas such as the Himalayas, which is considered a bio...

Using rapid amplification of cDNA ends (RACE)-PCR, two full-length cDNAs encoding putative seven-transmembrane receptors (designated Gh7TMpR1 and Gh7TMpR2) were cloned from cotton plants. Southern blot and an ApaL1 restriction site polymorphism analyses revealed that Gh7TMpR1 was derived from the ancestral A diploid genome, while Gh7TMpR2 was from the D subgenome. Northern blot hybridization in...

background: indirect genetic diagnosis using polymorphic dna markers can detect carriers of hemophilia a. this technique is preferable in developing countries because of its simplicity and cost effectiveness compared to direct mutation analysis. in the present study, we examined usefulness of intragenic marker bcl i restriction fragment length polymorphism (rflp) at intron 18, for carrier detec...

The dnaK gene and surrounding sequences from reference strains of the six Brucella species were amplified by the polymerase chain reaction (PCR) with primers chosen according to the published sequence of the B. ovis dnaK gene and studied for polymorphism with nine restriction endonucleases. The restriction patterns were identical for all species with all restriction endonucleases tested except ...

Length and restriction site polymorphism within a 2.8-kb threonine-rich open reading frame from Cryptosporidium parvum was identified and used to determine the genotypes of isolates from calves and humans. In agreement with observations of other genetic loci, all calf isolates were identical at this locus. In contrast, human isolates showed two profiles, one found exclusively in humans and one ...

We report the efficient concerted integration of a linear virus-like DNA donor into a 2.8 kbp circular DNA target by integrase (IN) purified from avian myeloblastosis virus. The donor was 528 bp, contained recessed 3' OH ends, was 5' end labeled, and had a unique restriction site not found in the target. Analysis of concerted (full-site) and half-site integration events was accomplished by rest...

Thirty-five nucleotide polymorphisms were found in a 21.5-kbp region including the Est6 locus among 42 isoallelic lines extracted from a single natural population of Drosophila melanogaster. The heterozygosity per nucleotide pair was estimated to be 0.010 overall, but was lower in sequences hybridizing to transcripts than in those not hybridizing to transcripts. Eleven of 36 pairwise comparison...

This investigation demonstrates the status of bovine anaplasmosis caused by A. marginale in bovines from Submountain and Undulating Zone of Punjab. Out of 184 suspected animals, 25 (19.51%), 47 (31.71%), and 78 (68.75%) were positive by microscopy, indirect ELISA, and PCR assay, respectively. The microscopy showed 29% sensitivity and 99% specificity, while ELISA showed 32% sensitivity and 79% s...
