a 9 bp deletion between cytochrome oxidase subunit ii and trna lys genes in mitochondrial dna, has proven to be an extremely informative marker for tracing population history. using the pcr-page and pcr-sscp techniques in this study, 152 dna samples collected from iranian populations were screened for the 9 bp deletion. no deletion was observed. a length polymorphism, most probably a 9 bp tripl...

Cowpox virus, in contrast to vaccinia virus, can multiply in Chinese hamster ovary cells. To study the genetic basis for this difference in host range, recombinants between vaccinia and cowpox viruses were isolated and their DNA restriction patterns were examined. The ability to multiply in Chinese hamster ovary cells could be correlated with the conservation of cowpox virus sequences mapping a...

The family Magnaporthaceae considered as a single-family placed in the order Magnaporthales. Currently, three distinct clades are phylogenetically distinguished in this order that one is referred as the Pyriculariaceae. The Pyriculariaceae is characterized as a novel family having new genera, new species, new combinations and neotypification (basionym). To taxonomically evaluate this family, an...

Soybean is an important source of plant protein used in human diets. Cadmium (Cd) from agricultural soil a toxic metal for plants, including soybean. Furthermore, the cadmium taken up to seeds soybean and becomes risk animals by feed food chain. A method avoid this represented selection breeding lines/cultivars with genetic potential minimized accumulation. This work reports approach assisted D...

MOTIVATION DNA microarray data analysis has been used previously to identify marker genes which discriminate cancer from normal samples. However, due to the limited sample size of each study, there are few common markers among different studies of the same cancer. With the rapid accumulation of microarray data, it is of great interest to integrate inter-study microarray data to increase sample ...

The minisatellite locus, BbMin1, was isolated from a partial Beauveria bassiana genomic library that consisted of poly(GA) flanked inserts. Polymerase chain reaction (PCR) of the BbMin1 repeat demonstrated allele size variation among 95 B. bassiana isolates. Amplification was also observed from single isolates of Beauveria amorpha, Beauveria brongniartii, and Beauveria caledonica. Eight alleles...

Deoxyribonucleic acid (DNA) extracted from purified virions of Shope fibroma virus (SFV) (by using DNA from Microccocus lysodeikticus as marker) had a buoyant density of 1.6996 +/- 0.0003 g/ml), hence a guanine plus cytosine (G + C) content of 40.4 +/- 0.3%, which is close to the G + C content of the DNA of susceptible rabbit cells (40.9 +/- 0.4%) and different from that of vaccinia virus DNA (...
