Background and purpose: E. coli bacteria is detected by culture, serology and molecular methods. In molecular methods PCR products are created using little random primers. The main purpose of this research was to study the genetic diversity of Escherichia coli bacteria. Also, the propinquity of isolated bacteria with two common strains of EnteroPathogenic E. coli (St.1) and EnteroHaemorrhagic E...
Genetic male sterility is controlled by one pair of ressesive allele (aa) in sugar beet. This trait is used in most breeding programes. The exsistance of the character in a line or population facilitates transfer of important trait to the breeding material (for example resistance to plant disease). Also, it is possible to increase genetic diversity of monogerm populations by using genetic ma...

We studied the applicability of intersimple sequence repeat (ISSR) polymorphism in cotton. We found that: (i) the resolving power of agarose gels is poor relative to that provided by sequencing gels; (ii) fluorescent labelling of ISSR amplification primers produced numerous scorable bands; (iii) primer mixing (double priming) generated more bands than the sum of fragments resulting from two sin...
Amplified fragment length polymorphism (AFLP) technique was used to assess genetic relationships among 20 grapevine rootstocks in Turkey. Discrimination of the rootstocks with 10 primer combinations yielded 1366 bands on AFLP gels; 65% of them were polymorphic. The rootstocks revealed two main clusters; one of them comprised two (Malégue and Harmony) and the other 18 genotypes. The Ber x Rip hy...
Three Malaysian ginger cultivars (Bukit Tinggi, Tanjung Sepat and Sabah) were collected and examined for genetic polymorphisms using microsatellite DNA primers. The single microsatellite oligonucleotide primers (CATA)5, (GATA)5 and (GAC)6 were used in polymerase chain reactions (PCRs). These PCR reactions produced 7 polymorphic bands with an average of 2.334 polymorphic bands per primer, leadin...
Identification and classification of genetic source are important in plant breeding and genetic diversity. In order to evaluate genetic diversity of 48 Facultative wheat genotypes belong to north of IRAN, an experiment was done using 10 ISSR primers in the genetic laboratory of Gonbad Kavous University. Out of 62 produced fragments, 41 fragments were polymorphic. The number of polymorphic bands...
Genetic variations of 15 Brahmi (Bacopa monnieri L.) accessions were evaluated using random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. During RAPD analysis, amplification of genomic DNA of the 15 accessions by 22 primers generated 197 fragments, of which 187 were polymorphic with an average of 8.95 bands per primer. The amplified products varied in size f...
In this study, genetic diversity was evaluated for 40 landraces and improved rice genotypes by inter-simple sequence repeat (ISSR), IRAP (Inter-Retrotransposon Amplified) and REM (Retro transposon-Microsatellite AmplifiedPolymorphism) marker systems. Amplified productions of 20 primers indicated distinct and polymorphic bands among genotypes that produced a total of 309 bands and an average of ...
Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic relationships between two seasonal immigrant forms (namely fall-run and spring-run) of Caspian trout Salmo trutta caspius. In this regard, 62 fin tissue samples were collected from southern parts of the Caspian Sea basin and examined with 16 oligodecamer primers to asses their genetic diversity as well as probable s...
