Pepper species exhibit broad genetic diversity, which enables their use in breeding programs. The objective of this study was to characterize the diversity between the parents of different species and their interspecific hybrids using morphological and molecular markers. The parents of Capsicum annuum (UFPB-01 and -137), C. baccatum (UFPB-72), and C. chinense (UFPB-128) and their interspecific hybrids (01x128, 72x128, and 137x128) were used for morphological and molecular characterization.

Genetic characterization of native and invasive Plagioscion squamosissimus (Perciformes, Sciaenidae) populations in Brazilian hydrographic basins

R. S. Panarari-Antunes, Prioli, A. J., Prioli, S. M. A. P., Júlio, Jr, H. F., Oliveira, A. V., Agostinho, C. S., Filho, J. P. Silva, and Prioli, L. M., Genetic characterization of native and invasive Plagioscion squamosissimus (Perciformes, Sciaenidae) populations in Brazilian hydrographic basins, vol. 14, pp. 14314-14324, 2015.

The genetic diversity of invasive and native populations of Plagioscion squamosissimus (Heckel, 1840) from the Paraná, Parnaiba and Araguaia-Tocantins river basins was assessed by using Random Amplified Polymorphic DNA (RAPD) markers. Genetic data confirmed the hypothesis of low genetic variability within and among P. squamosissimus populations introduced in the upper Paraná River basin, and indicated that they likely originated from a common ancestor. Moreover, the data demonstrated that, in agreement with available historical records, the P.

Genetic relatedness of artichoke (Cynara scolymus L.) hybrids using random amplified polymorphic DNA (RAPD) fingerprinting

M. A. Sharaf-Eldin, Al-Tamimi, A., Alam, P., Elkholy, S. F., and Jordan, J. R., Genetic relatedness of artichoke (Cynara scolymus L.) hybrids using random amplified polymorphic DNA (RAPD) fingerprinting, vol. 14, pp. 18431-18439, 2015.

The artichoke (Cynara scolymus L.) is an important food and medicinal crop that is cultivated in Mediterranean countries. Morphological characteristics, such as head shape and diameter, leaf shape, and bract shape, are mainly affected by environmental conditions. A molecular marker approach was used to analyze the degree of polymorphism between artichoke hybrid lines. The degree of genetic difference among three artichoke hybrids was evaluated using random amplified polymorphic DNA-PCR (RAPD-PCR).

Genetic diversity analysis in Tunisian perennial ryegrass germplasm as estimated by RAPD, ISSR, and morpho-agronomical markers

S. Ghariani, Elazreg, H., Chtourou-Ghorbel, N., Chakroun, M., and Trifi-Farah, N., Genetic diversity analysis in Tunisian perennial ryegrass germplasm as estimated by RAPD, ISSR, and morpho-agronomical markers, vol. 14, pp. 18523-18533, 2015.

Tunisia is rich in diverse forage and pasture species including perennial ryegrass. In order to enhance forage production and improve agronomic performance of this local germplasm, a molecular analysis was undertaken. Random amplified polymorphic DNA (RAPD), inter simple sequence repeats (ISSR) and morpho-agronomical traits markers were used for genetic diversity estimation of ryegrass germplasm after screening 20 spontaneous accessions, including a local and an introduced cultivars.

Genetic analysis of five sedentary fish species in middle Laranjinha River (upper Paraná River basin): A case study

W. Frantine-Silva, Ferreira, D. G., Nascimento, R. H. C., Fracasso, J. F., Conte, J. E., Ramos, F. P., Carvalho, S., and Galindo, B. A., Genetic analysis of five sedentary fish species in middle Laranjinha River (upper Paraná River basin): A case study, vol. 14, pp. 18637-18649, 2015.

Most studies of diversity and genetic structure in neotropical fish have focused on commercial species from large rivers or their reservoirs. However, smaller tributaries have been identified as an important alternative migratory route, with independent pools of genetic diversity. In this context, the present study aimed to evaluate genetic diversity and structure in five neotropical fish species from a region of Laranjinha River in the upper Paraná River basin.

Genetic diversity in Tunisian populations of faba bean (Vicia faba L.) based on morphological traits and molecular markers

I. Z. Backouchi, Aouida, M., Khemiri, N., and Jebara, M., Genetic diversity in Tunisian populations of faba bean (Vicia faba L.) based on morphological traits and molecular markers, vol. 14, pp. 7587-7596, 2015.

Genetic diversity within Vicia faba L. is key to the ge­netic improvement of this important species. In this study, morphologi­cal traits and RAPD molecular markers were used to assess the levels of polymorphism across 12 Tunisian populations, three major and nine minor from different locations. Analysis of morphological traits indi­cated that the three major populations showed significant differences and the nine minor populations exhibited considerable variation for most traits. The grain yield of the Alia population could be increased by inoculation.

Populations of Erythrina velutina Willd. at risk of extinction

M. F. V. Melo, Gonçalves, L. O., Rabbani, A. R. C., Álvares-Carvalho, S. V., Pinheiro, J. B., Zucchi, M. I., and Silva-Mann, R., Populations of Erythrina velutina Willd. at risk of extinction, vol. 14, pp. 10298-10307, 2015.

The goal of this study was to characterize the structure of two natural populations of the coral tree using RAPD and ISSR markers. The study evaluated all individuals in two different areas in the northeastern region of Brazil: the first was in the riparian area, 10 km x 100 m along the edge of the lower São Francisco River, and the second was in the municipality of Pinhão, in a semiarid region between the municipalities of Neópolis and Santana do São Francisco. We used all the coral trees present in those two areas (37 individuals).
