A PCR primer specific to Nocardia farcinica was prepared based on sequence information of random amplified polymorphic DNA (RAPD) analysis. The PCR primer amplifies N. farcinica species only; no amplification was observed in 25 other Nocardia strains that we tested. Specificity of the primer for N. farcinica was also confirmed using other fungal and bacterial strains that are frequently isolate...

101 isolates of Brucella spp. including the reference (n=7) and the Iranian field strains belonging to last years 1961-2003 (n=94) were biotyped and classified into 9 biotypes. Random amplified polymorphic DNA (RAPD) analysis using a ten mer-AP4 primer was generated 72 reproduciable DNA band. The typeability was 100%. The thirteen isolates were classified into five groups, each containing 2-4 b...

Givotia rottleriformis Griff. is an economically important dioecious tree species known for the softwood used in making toys. Knowledge of genetic variation in a dioecious tree species is important for devising strategies for its successful management and conservation. Studies were conducted to examine the genetic variation in Givotia plants using RAPD (random amplified polymorphic DNA) analysi...

Metagenome, a mixture of different genomes (as a rule, bacterial), represents a pattern, and the analysis of its composition is, currently, one of the challenging problems of bioinformatics. In the present study, the possibility of evaluating metagenome composition by DNA-marker methods is investigated. These methods are based on using primers, short nucleic acid fragments. Each primer picks ou...

A chromosome walking method was improved in this work. The new method was named as nonspecific primer anchored PCR (NPA-PCR). Nested gene specific primers were designed based on the known region and long random primer using degeneracy oligonucleotides for nonspecific anchoring. Annealing temperatures were varied to control the priming. Target sequences were obtained by PCR with random primer an...
