The amplified fragment length polymorphism (AFLP) method was used to evaluate genetic diversity and to assess genetic relationships within the section Mentha in order to clarify the taxonomy of several interspecific mint hybrids with molecular markers. To this end, genetic diversity of 62 Mentha accessions from different geographic origins, representing five species and three hybrids, was asses...
Amplified fragment length polymorphism (AFLP) analysis of botanical forensic evidence provides a means of obtaining a reproducible DNA profile in a relatively short period of time in species for which no sequence information is available. AFLP profiles were obtained for 40 Acer rubrum trees. Leaf material from five additional species was also typed. Genomic DNA was isolated using the DNeasy Pla...
Amplified fragment length polymorphism (AFLP) and inter-simple sequence repeat markers were employed to characterize a genetic resource collection of Miscanthus, a grass under trial in Europe as a biomass crop. The 26 polymorphic markers produced by two ISSR fingerprinting primers were able to discriminate taxa and identify putative clones. AFLP fingerprints were fully reproducible and produced...
A PCR protocol for the rapid diagnosis of fish 'pasteurellosis' based on 16S rRNA gene sequences was developed. The procedure combines low annealing temperature that detects low titers of Photobacterium damselae but also related species, and high annealing temperature for the specific identification of P. damselae directly from infected fish. The PCR protocol was validated on 19 piscine isolate...
We examined the genetic diversity of papaya (Carica papaya) based on morpho-agronomic and molecular data. Twenty-seven genotypes grown in Brazil were analyzed with 11 AFLP primer combinations, 23 ISSR markers, 22 qualitative, and 30 quantitative descriptors. For the joint analyses, we used the Gower algorithm (Joint Gower) and the average value of the individual dissimilarity matrix for each ty...
Dry pollen of diploid Solanum clone 9507-04, Cotton chromosomal substitution line and Echinacea purpurea „Magnus‟ were isolated and their cells contents released in individual tubes containing water or pollen germination media, respectively.Six polymorphic markers from individual pollen grains of the diploid potato were amplified using two random amplified polymorphic DNA (RAPD) primers, i.e., ...
Taraxacum koksaghyz Rodin (TKS) has been studied in many occasions as a possible alternative source for natural rubber production of good quality and for inulin production. Some tire companies are already testing TKS tire prototypes. There are also many investigations on the production of bio-fuels from inulin and inulin applications for health improvement and in the food industry. A limited am...
An amplified fragment length polymorphism (AFLP) method, developed to genotype Yersinia enterocolitica, has been used to investigate 70 representative strains isolated from humans, pigs, sheep, and cattle in the United Kingdom. AFLP primarily distinguished Y. enterocolitica strains according to their biotype, with strains dividing into two distinct clusters: cluster A, comprising largely the pu...
AIMS To evaluate the intraspecific diversity of the fish pathogen Flavobacterium columnare. METHODS AND RESULTS Genetic variability among Fl. columnare isolates was characterized using restriction fragment length polymorphism analysis of the 16S rDNA gene, intergenic spacer region (ISR) sequencing, and amplified fragment length polymorphism (AFLP) fingerprinting. Thirty Fl. columnare cultures...
Jacaranda decurrens (Bignoniaceae) is an endemic species of the Cerrado with validated antitumoral activity. The genetic diversity of six populations of J. decurrens located in the State of São Paulo was determined in this study by using molecular markers for randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP). Following optimization of the amplification ...
