leaf blotch disease of barley, caused by rhynchosporium secalis is a major disease of barley in iran. its worldwide occurrence and economic importance in barley production has motivated studies on the population genetic structure of this pathogen. random amplified polymorphic dna (rapd) method was utilized to investigate the genetic diversity of populations of r. secalis isolated from barley le...

The purpose of the present study was to evaluate the effects of four experimental primers on bond strength between a self-curing luting agent and silver-palladium-gold alloy. The experimental primers were in mixed solutions of a thiouracil primer (Metaltite) and a phosphate primer (Epricord, PM, PE, or PP), which were designated as Metaltite/Epricord, Metaltite/PM, Metaltite/PE, and Metaltite/P...

The human immunodeficiency virus (HIV) and other retroviruses show extensive genomic variation, which is primarily due to error-prone replication by the viral reverse transcriptase (RT) enzymes. RT errors include misincorporation with subsequent extension of the mismatched terminal base, and extension of realigned primer-template duplexes. Whereas both RT-mediated mechanisms have been extensive...
