A multiplex terminal restriction fragment length polymorphism (M-TRFLP) fingerprinting method was developed and validated for simultaneous analysis of the diversity and community structure of two or more microbial taxa (up to four taxa). The reproducibility and robustness of the method were examined using soil samples collected from different habitats. DNA was PCR amplified separately from soil...

Soil fungal community structures are often highly heterogeneous even among samples taken from small field plots. Sample pooling is widely used in order to overcome this heterogeneity, however, no objective criteria have yet been defined on how to determine the number of samples to be pooled for representatively profiling a field plot. In the present study PCR/RFLP and T-RFLP analysis of fungal ...

This application note shows how the Agilent 2100 Bioanalyzer was used in polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) fragment analysis for fish species identification. A 464bp cytochrome-b target sequence, found in all vertebrate fish, was first amplified and then digested with restriction enzymes. The fragments were resolved on the DNA 500 LabChip®, allowing s...

OBJECTIVES The aim of the present work was to standardise a PCR-Restriction Fragment Length Polymorphism analysis (PRA) as a tool to detect the mycobacteriologic composition of lepromas from leprosy patients used in the production of lepromin to improve the quality of the Mitsuda test. DESIGN PCR-Restriction Fragment Length Polymorphism analysis using hsp65 and rpoB genes were applied to 11 r...

ABSTRACT The barley cv. Bolivia carries two leaf rust (Puccinia hordei) resistance genes, Rph2 and Rph6, and is the only known source of the latter gene. A resistant line (Bolivia-Rph6) carrying Rph6 only was obtained in the F(4) generation of a cross between cv. Bolivia and the susceptible cv. Bowman via progeny testing with differential isolates of the leaf rust pathogen. Genetic analyses and...
