Four molecular approaches to determining the types of Candida albicans strains were compared. The strains used were those whose repeated DNA (ribosomal and mitochondrial) EcoRI restriction fragment length polymorphisms (RFLP) were determined by Stevens et al. (D. A. Stevens, F. C. Odds, and S. Scherer, Rev. Infect. Dis. 12:258-266, 1990). Scherer and Stevens (S. Scherer and D. A. Stevens, Proc....

Genotyping-by-sequencing (GBS) has emerged as a useful genomic approach for exploring genome-wide genetic variation. However, GBS commonly samples a genome unevenly and can generate a substantial amount of missing data. These technical features would limit the power of various GBS-based genetic and genomic analyses. Here we present software called IgCoverage for in silico evaluation of genomic ...

A full length, double-stranded ovalbumin complementary DNA (cDNA) was synthesized in vitro and used to assay the action of 35 restriction endonucleases upon this DNA sequence. Some 22 enzymes, Bal I, BamHl, Blu I and its isoschizomerXho I, Ppu 1,Xba I, Tag I, Sal I, Bgl I, Bgl II, Kpn I, Sst II, Hue II, Hpa I, Hap II, Hha I, Hind11 and its isoschizomer HincII, Hind111 and its isoschizomer Hsu I...

The left-end adenovirus type 3 DNA sequence is very similar to those of other subgroup B adenoviruses, especially in the area between the HinfI site (320 base pairs) and the early-region Ia gene. This segment of the genome has been implicated as necessary for the left-end polarity of adenovirus DNA encapsidation. This segment and the sequences flanking it are compared with the corresponding seq...

β(S) haplotypes were studied in 47 non-related patients with sickle-cell anemia from the state of Rio Grande do Norte, Brazil. Molecular analysis was conducted by PCR/RFLP using restriction endonucleases XmnI, HindIII, HincII and HinfI to analyze six polymorphic sites from the beta cluster. Twenty-seven patients (57.5%) were identified with genotype CAR/CAR, 9 (19.1%) CAR/BEN, 6 (12.8%) CAR/CAM...

Polymerase chain reaction (PCR) was used to amplify a specific 1.8-kb sequence of mitochondrial DNA from single juveniles and eggs from 17 populations of Meloidogyne incognita, M. hapla, M. javanica, and M. arenaria. Approximately 2 mug amplified product were produced per reaction. Restriction digestion of the amplified product with HinfI permitted discrimination of clonal lineages of the four ...

O presente estudo teve por objetivo realizar a identificação dos fungos encontrados na própolis produzido Apis mellifera L. da Baía do Iguape, Brasil. Para tanto, foram utilizadas técnicas morfológicas, bioquímicas e moleculares, sendo averiguado o perfil de restrição gerado espaçador interno transcrito (ITS1 ITS4). tamanho produtos PCR foi analisado quanto ao obtidos com endonuclease (HhaI, Ha...
