Morphologically, nine different slow-growing protoclones were screened from regenerated protoplast of heterokaryotic Agaricus bisporus. The present study is the first report of fingerprinting on differentiating homo- and heterokaryotic protoclones using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) markers. Among 80 primers tested, the seven ISSR and seven RAPD...

Here we describe the application of a random amplified polymorphic DNA (RAPD) analysis for molecular genetic typing avian pathogenic Escherichia coli (APEC) strains. The RAPD technique was shown to be highly reproducible. Stable banding patterns with a high discriminatory capacity were obtained using two different primers. Overall, 55 E. coli strains were analyzed with a RAPD technique. The RAP...

The Bacillus subtilis genome encodes eleven Rap proteins, which are conserved tetratricopeptide-containing regulatory proteins. Of those characterized to date, all except RapI negatively regulate response regulators, including Spo0F, ComA and DegU, via protein-protein interactions. RapD has not yet been fully characterized. It was examined whether RapD inhibits the expression of spoIIE, srfA an...

Methods for identifying isolates of various pathogenic bacteria by DNA fingerprinting with random primers (RAPD) have been described recently. In these methods many primers are screened and the primers that generate the most informative DNA pattern are selected. A new strategy that simplifies the primer selection process for RAPD fingerprinting has been developed in our laboratory. In this appr...

Purpose: To quantify the specificity and sensitivity of RTVue-100, Optovue parameters at determining the presence of a relative afferent pupillary defect (RAPD) by coupling their values with the instrument normative data base (NDB) and the presence of a RAPD. To generate the distribution for the focal loss volume (FLV) percentage, by coupling its value to the instrument NDB and presence of a RA...

Random-amplified-polymorphic-DNA(RAPD) was assayed to detect the genetic variation of 6 barley generations from Iraq. Four primers generated a total 17 scoreable bands in RAPD analysis) and resolving power, three polymorphic differed (Rp). The use marker systems distance among generation discovered be beneficial. dendrograms indicate diverse grouping barely specimens, although we did see that c...

Random amplified polymorphic DNA (RAPD) markers are used widely to develop high resolution genetic maps and for genome fingerprinting. Typically, single oligomers of approximately 10 nucleotides are used to PCR amplify characteristic RAPD marker fragments. We describe an efficient method for the direct end-sequencing of gel-purified RAPD fragments using one primer from a set of four 3'-terminal...
