Sequence-related amplified polymorphism (SRAP), amplified fragment length polymorphism (AFLP), and inter-simple sequence repeat (ISSR) markers were used to estimate the genetic diversity and relationships among Eucommia ulmoides cultivars in China. A total of 240, 192, and 150 DNA fragments were detected by 10 SRAP primer combinations, 10 AFLP primer combinations, and 10 ISSR primers, among whi...

Macrophomina phaseolina (Tassi) Goid is one of the most important soil-borne fungi that affects sesame and causes charcoal rot disease, with a great economic challenge to growers worldwide. Pathogenic molecular characterizations eleven M. isolates collected from different geographical regions in Egypt were carried out determine pathogenicity genetic diversity. Pathogenicity tests showed pathoge...

Background: Arecanut (Areca catechu L.) is an important plantation crop of India belongs to the family Arecaceae. As it a highly cross-pollinated there significant difference among genotypes. Morphological traits used for determining diversity and relationships genotypes or variety are prone environmental influences. Thus, usefulness molecular markers has been investigated as means characterizi...

Earthworms are one of the most important and beneficial macrofauna, and are used extensively in organic farming. Earthworms mediate soil biological regulation systems, and produce biogenic structures. They help to maintain soil structure, water infiltration, and regulate the availability of nutrients assimilated by plants. The objectives of this study were to perform morphological and molecular...

The wild mint "Mentha longifolia (L.) Hudson subsp. noeana (Briq.) Briq." is an important medicinal plant which contains several worthy components like: menthone, pulegone, pipertenon, menthol, thymol, and carvone in its essential oil. This plant grows extensively in center of Asia including Iran. Because of so worthy components and its big role in traditional and modern medicine, the wild mint...

In the present study, genetic diversity among 16 collections of Stevia rebaudiana Bertoni was assessed to compare the efficiency of two-marker systems over one marker using RAPD and ISSR markers. How well these two marker systems discriminated the Stevia collections was compared. In fact, all the Stevia accessions included in the present study have been growing under different altitudes, rangin...

Diploid Thinopyrum elongatum, a wild relative of wheat, contains many agronomically desirable traits and has potential for increasing genetic variability and introducing desirable characters in this crop. Few molecular markers are available for rapid screening of T. elongatum genome segments in the wheat genetic background. We used 36 RAPD primers and 33 ISSR primers to screen for polymorp...

out of fifty-two iranian nonaflatoxigenic strains of aspergillus flavus, which were collected from various substrates (soil and kernel) and sources (peanut, corn and pistachio), fifteen representatives were selected according to their different geographical origins (six provinces: guilan and golestan, ardebil, fars, kerman and semnan) and vegetative compatibility groups (vcgs, ir1 to ir15) for ...

in the present study, random amplified polymorphic dna (rapd) and inter-simple sequence repeat (issr) markers were used to estimate genetic diversity and relationships among 35 cluster bean [cyamopsis tetragonoloba (l.) taub] genotypes. for rapd analysis, 20 random primers were used which amplified 164 bands, 147 of which were polymorphic with an average polymorphism of 90.3%. the amplified pro...

Improvement of high yielding, disease resistant silkworm strains became imminent to increase production of silk, which is a major revenue earner for sericulturists. Since environment interacts with phenotype, conventional breeding did not result in commendable yield improvement in synthetic strains of silkworm, Bombyx mori. Identification of DNA markers associated with different economically im...
