Kumar A, Verma N. 2012. A comparative phylogenetic analysis of medicinal plant Tribulus terrestris in Northwest India revealed by RAPD and ISSR markers. Biodiversitas 13: 107-113. Several DNA marker systems and associated techniques are available today for fingerprinting of plant varieties. A total of 5 RAPD and 8 ISSR primers were used. Amplification of genomic DNA of the 6 genotypes, using RA...

genetic diversity of 22 morphotypes of diploid wheat (t. urartu) was investigated using morphological traits and rapd markers. morphological characterizations were carried out based on 17 traits and statistical parameters of dispersion and diversity of agronomic traits were calculated. statistical analysis showed significant differences for all characters among morphotypes. dendrograms were gen...

Sequence characterized amplifled region (SCAR) markers were derived from random amplified polymorphic DNAs (RAPDs) that segregate in a longleaf pine x slash pine Fi family. Nine RAPD fragments, five from longleafpine and four from slash pine, were cloned and end sequenced. A total of 13 SCAR primer pairs, with lengths between 17 and 24 nucleotides, were developed. Nine (for SCAR loci FGPO04, FG...

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...

Eucommia ulmoides Oliver, the only extant species of Eucommiaceae, is a second-category state-protected endangered plant in China. Evaluation of genetic diversity among some intraspecific hybrid populations of E. ulmoides Oliver is vital for breeding programs and further conservation of this rare species. We studied the genetic diversity of 130 accessions from 13 E. ulmoides intraspecific hybri...

In this study, we evaluated three PCR-based methods for the molecular typing of nonpathogenic Fusarium oxysporum isolates: random amplified polymorphic DNA (RAPD), polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and amplified fragment length polymorphism (AFLP). The analyses were performed using 64 isolates of F. oxysporum collected from cotton-producing areas in E...

A field population of Heterodera glycines was inbred by a combination of controlled male-female matings and inoculation of soybean with second-stage juveniles (J2) from single cysts. The initial and four F inbred populations were subjected to random amplified polymorphic DNA analysis and were also tested for their ability to reproduce on race differentials. The RAPD patterns of the inbred popul...

in this study, the genetic diversity of 25 iranian saffron genotypes from three species (crocus speciosus, crocus cancellatus and crocus sativus) has been evaluated using 16 morphological traits and rapd marker. c. sativus was different with speciosus in the leaf number per plant, tepal length, flower weight, inflorescence stem height and the stigma length, but had no significant difference wit...

Mango is one of the most commercially important fruit crops in tropical and subtropical regions. To increase the efficiency of breeding strategies, two EST-derived marker systems were developed in the present study using information from the mango fruit transcriptome. Using simple sequence repeats, 218 of 230 primer pairs showed stable amplification for 7 mango genotypes with amplicons ranging ...
