13. Joint analysis of phenotypic and molecular diversity provides new insights on the genetic variability of the brazilian physic nut germplasm bank
The genetic variability of the Brazilian physic nut (Jatropha curcas) germplasm bank (117 accessions) was assessed using a combination of phenotypic and molecular data. The joint dissimilarity matrix showed moderate correlation with the original matrices of phenotypic and molecular data. However, the correlation between the phenotypic dissimilarity matrix an

14. Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in Paspalum notatum
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related se

15. Identification of RAPD and SCAR markers associated with yield traits in the Indian tropical tasar silkworm Antheraea mylitta drury
The tropical tasar silkworm, Antheraea mylitta, is a semi-domesticated vanya silk-producing insect of high economic importance. To date, no molecular marker associated with cocoon and shell weights has been identified in this species. In this report, we identified a randomly amplified polymorphic DNA (RAPD) marker and examined its inheritance, and also devel

16. Identificação molecular e produção de pectinases por isolados de Cladosporium cladosporioides (Fres.) de Vries / Molecular identification and production pectinase by isolates Cladosporium cladosporioides (Fres.) de Vries
The enzymes market has grown considerably in recent years. These enzymes play an important role in various industries, mainly in the food industry. Special attention has been given to the search for alternatives that reduce production costs and developing processes that will not harm the environment. Disposal of waste is a major problem faced by many agribus

17. 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.

18. Limited vegetative compatibility as a cause of somatic recombination in Trichoderma pseudokoningii
With the aim of a better characterization of the somatic recombination process in Trichoderma pseudokoningii, a progeny from crossings between T. pseudokoningii strains contrasting for auxotroph markers was characterized by RAPD markers and PFGE (electrophoretic karyotype). Cytological studies of the conidia, conidiogenesis and heterokaryotic colonies were a

19. 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. Assessment of genetic diversity in Cattleya intermedia Lindl. (Orchidaceae)
Orchids are valuable pot plants and Cattleya intermedia is a promising species underused in breeding programs. Recently, breeding work with this species produced superior plants that are believed to be not the true species owing to the morphological differences from wild plants. The aim of this study was to estimate the level of genetic diversity and interre

21. Genetic variability of brycon orbignyanus (valenciennes, 1850) (characiformes: characidae) in cultivated and natural populations of the upper paraná river, and implications for the conservation of the species
This study aimed to evaluate the genetic variability of B. orbignyanus in cultivated and natural populations of the Upper Paraná River, using molecular RAPD markers and mtDNA control region. Specimens were collected in the Paraná River and in the Piracema fish farm in Maringá, State of Paraná, Brazil. RAPD primers produced 82 loci with consistent express

22. Genetic differentiation in natural populations of Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae) with different phenotypic spot patterns on tergites in males
Entomological surveys in the state of Maranhão have recorded morphologically distinct populations of Lutzomyia longipalpis (Lutz & Neiva). Some populations have one pair of spots (1S) on the fourth tergite, while others have two pairs (2S) on the third and fourth tergites of males. In the present study we investigated the degree of genetic polymorphism amon

23. Use of RAPD molecular markers on differentiation of brazilian and chinese Ganoderma lucidum strains
The aim of this work was to analyze the Brazilian and Chinese strains of Ganoderma lucidum with molecular RAPD markers. A similarity matrix was elaborated and the RAPD profiles of G. lucidum strains were also compared to two other Ganoderma spp: G. applanatum and G. lipsiense in order to produce genetic similarity among the species. Based on the primers used
