13. Genetic variation in cultivated Rheum tanguticum populations
To examine whether cultivation reduced genetic variation in the important Chinese medicinal plant Rheum tanguticum, the levels and distribution of genetic variation were investigated using ISSR markers. Fifty-eight R. tanguticum individuals from five cultivated populations were studied. Thirteen primers were used and a total of 320 DNA bands were scored. Hig

14. Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene
Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene. Green lacewings are generalist predators, and the species Chrysoperla externa presents a great potential for use in biological control of agricultural pests due to its high predation and reproduction capacities, as we

16. Genetic similarity among strawberry cultivars assessed by RAPD and ISSR markers
Most strawberry (Fragaria × ananassa Duchesne) cultivars used in Brazil are developed in other countries, it became clear the need to start the strawberry breeding program in the country. To start a breeding program is necessary the genetic characterization of the germplasm available. Molecular markers are important tools that can be used for this purpose.

17. Efficiency of RAPD and ISSR markers in assessing genetic variation in Arthrocnemum macrostachyum (Chenopodiaceae)
The goal of this study was to investigate the molecular characterization of A. macrostachyum genotypes grown in the Western coast of Syria using RAPD and ISSR techniques. PCR amplifications with 20 RAPD primers gave an average of 9.25 selected markers/ primer, with a maximum of 17 (OPG05) and a minimum of four (OPA02). Percentage of polymorphic bands ranged

20. UtilizaÃÃo de tÃcnicas multivariadas e moleculares na caracterizaÃÃo e seleÃÃo de genÃtiopos de feijÃo-caupi de porte ereto e ciclo precoce / use of multivariate techniques and molecular characterization and selection of erect and early cowpea genotypes
Cowpea has great socioeconomic importance in relation to their high contents of protein, drought resistance and good yield. Being cultivated in tropical and subtropical regions of Africa, Brazil and Asia, cowpea is cultivated predominantly by small farmers who use few technological resources. In recent years, cowpea has drawn the attention of medium and larg

21. Construction of cowpea genetic map using ISSR, DAF e CAPS markers / ConstruÃÃo de um mapa genÃtico para feijÃo-caupi com marcadores moleculares ISSR, DAF E CAPS
Cowpea crop is of great economical importance in Brazil being the Northeastern region the main producer. The low levels of resistance to pathogens is one of the restricting factors for the Brazilian competitiveness worldwide. One of the most important disease is caused by Cowpea severe mosaic virus - CPSMV. The control of CPSMV can be achieved whit the use o

24. Comparison of PCR-based molecular markers for the characterization of Proteus mirabilis clinical isolates
Proteus mirabilis is one of the most important pathogens associated with complicated urinary tract infections (acute pyelonephritis, bladder infections, kidney stones) and bacteremia, affecting patients with anatomical abnormalities, immunodeficiency, and long-term urinary catheterization. For epidemiological purposes, various molecular typing methods, such
