Random amplified polymorphic DNA (RAPD) was used to detect polymorphisms among Zaprionus indianus fly populations collected from six municipalities in the States of São Paulo and Minas Gerais, Brazil. This species is an important, recently introduced fruit fly pest of figs and other fruit. Among 21 primers, 16 produced 73 reproducible polymorphic fragments; primer AM-9 produced the greatest num...

asafoetida is the dried latex exuded from the living underground rhizome or tap root of ferula assafoetida. antibacterial characteristic of asafoetida was shown using the circular zone diameter of bacterial growth inhibition by disk-diffusion method on two gram positive and three gram negative bacteria. then, the bacterial genomic dna damage, induced by f. assafoetida latex, was demonstrated us...

Ajowan is one of the most important members of medicinal plants of the Apiaceae, consumed by humans. The aim of this study was to explore genetic variability of 20 ajowan populations by ISSR fingerprinting and evaluation of traits at germination. Out of the 30 ISSR primers, ten generated reproducible and polymorphic bands. A total of 93 bands were detected out of which 65 were polymorphic. High...

DNA based molecular markers allow precise, objective and rapid cultivar identification. In this study, five ISSR and two sets of fluorescence-labeled TP-M13-SSR markers were applied for discrimination of eight closely related wheat cultivars. Five ISSR primers revealed a total of 43 distinct reproducible bands, 29 (67.44%) of the 43 bands were polymorphic. The number of polymorphic bands detect...

Radix Astragali has been an important traditional Chinese herbal medicine for over 2000 years. It is derived from two plant species, namely, Astragalus mongholicus [Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao] and Astragalus membranaceus [Astragalus membranaceus (Fisch.) Bge.] (Leguminosae), according to the Pharmacopoeia of the People’s Republic of China. In this study,...

The Catskill Mountains of New York State are an important source of wild-collected American ginseng (Panax quinquefolium) and, increasingly, of woods-cultivated ginseng. The objective of this study was to assess genetic diversity among 9 different wild ginseng populations in and adjacent to the Catskill Mountain region of New York State and to compare these to wild populations from other states...

We optimized RAPD techniques by increasing the length of RAPD primers and performing a strict screening of PCR annealing temperature to distinguish 60 sweet orange cultivars from the Research Institute of Pomology at the Chinese Academy of Agricultural Sciences. A new approach called cultivar identification diagram (CID) was used to improve the efficiency of RAPD markers for cultivar ident...

The goals of this investigation were to identify and evaluate the use of polymorphic microsatellite marker (PMM) analysis for molecular typing of seventeen plant pathogenic fungi. Primers for di-, tri-, and tetranucleotide loci were designed directly from the recently published genomic sequence of Mycospherlla graminicola and Fusarium graminearum. A total of 20 new microsatellite primers as eas...

Eggplant is a major crop in Turkey, which produces more of this crop than all of Europe; consequently, germplasm resources are of concern for the country. Molecular characterization of eggplant genotypes collected from different geographical regions of Turkey was carried out using SSR and RAPD markers. With amplification of five SSR loci, the number of alleles per microsatellite locus ranged fr...
