We employed RAPD and sequence-related amplified polymorphism (SRAP) markers to evaluate polymorphisms in 15 tomato (Solanum lycopersicon) genotypes that were obtained from a tomato breeding program. Four local tomato genotypes selected from the Sanliurfa province (Southeastern Anatolia Region of Turkey), 10 heat-tolerant tomato genotypes, received from the Asian Vegetable Research and Developme...

BACKGROUND As for human trichomoniasis the host-parasite relationship is very complex, and the broad ranges of clinical symptoms are unlikely be attributable to a single pathogenic mechanism. Specific Random Amplified Polymorphic DNA (RAPD) markers of 490 bp, 720 bp and 460 bp using the primers Tv-5, OPA-6 and OPA-11, respectively, were reported. This was the first description of possible genet...

Abstract Fusarium head blight (FHB) is consistently one of the most important barley diseases worldwide. This study aimed to evaluate pathogenicity 16 isolates four species under controlled conditions and their genetic variability using 22 random amplified polymorphic DNA (RAPD) markers. Pathogenic variation was characterized based on disease development rates index two Syrian landraces with va...

Wild olive (O. europaea ssp cuspidata) plants grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 RAPDs and 10 ISSR markers. The mean value of polymorphism for RA...

The Solanum brevidens genome (2n = 2x = 24) was examined with randomly applied polymorphic DNA (RAPD) markers in a second backcross population derived from a S. brevidens + S. tuberosum somatic hybrid. RAPD markers cosegregated into 12 different S. brevidens synteny groups. Most synteny groups were nonrecombinant. However, nearly 40% of the S. brevidens synteny groups detected in this populatio...

According to theory, F(2) hybrid breakdown (lethality or sterility) is due to incompatibilities between interacting genes of the different species (i.e., the breaking up of coadapted gene complexes). Detection of such incompatibilities is particularly straightforward in haplodiploid species, because virgin F(1) hybrid females will produce haploid recombinant F(2) males. This feature allows for ...

Genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (Musa acuminata cv. Dwarf Cavendish (AAA)) were studied using morphological and random amplified polymorphic DNA (RAPD) markers. Out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

Fifteen serotypes of E. coli isolated from poultry were subjected to RAPD-PCR using eight oligonucleotide random primers. Amplification with each of the primers resulted in generation of different DNA fingerprinting profile with varied number of bands. Dendrogram based generation of clustering of E. coli serotypes showed two major clusters. The polymorphic amplicons served as markers for E. col...

Species-specific Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) markers were used to identify four species related to Anopheles (Nyssorhynchus) albitarsis Lynch-Arribàlzaga from 12 sites in Brazil and 4 in Venezuela. In a previous study (Wilkerson et al. 1995), which included sites in Paraguay and Argentina, these four species were designated "A", "B", "C" and "D". It was...

Andrographis paniculata Nees. (AP) is a self-pollinated medicinal herb with a wide range of pharmaceutical properties, facing a low diversity in Malaysia. Cross-pollination of AP accessions leads to considerable rates of heterosis in the agro-morphological characteristics and anticancer phytochemicals of this eminent medicinal herb. However, the poor crossability of the plant at the interpopula...
