Development of a novel set of microsatellite markers for Lippia alba (Verbenaceae)

D. S. Rocha, Santos, C. P., Bajay, M. M., Campos, J. B., Blank, A. F., Pinheiro, J. B., and Zucchi, M. I., “Development of a novel set of microsatellite markers for Lippia alba (Verbenaceae)”, vol. 14, pp. 971-974, 2015.

Microsatellite primers were developed and optimized for Lippia alba to characterize the L. alba germplasm bank of Universidade de São Paulo. A genomic library enabled the design of 9 microsatellite primers. Six of the 9 primers yielded polymorphic products, which defined 2 groups in the bank. The data provide support to characterize germplasm banks, genetic breeding programs for L. alba, and other genetic diversity studies and classifications of species in the genus Lippia.

Morphological and genetic relationships between wild and domesticated forms of peppers (Capsicum frutescens L. and C. chinense Jacquin)

S. I. C. Carvalho, Ragassi, C. F., Bianchetti, L. B., Reifschneider, F. J. B., Buso, G. S. C., and Faleiro, F. G., “Morphological and genetic relationships between wild and domesticated forms of peppers (Capsicum frutescens L. and C. chinense Jacquin)”, vol. 13, pp. 7447-7464, 2014.

Capsicum chinense and C. frutescens peppers are part of the Brazilian biodiversity, and the Amazon basin is the area of greatest diversity for them, especially for that former species. Nevertheless, little is known about their evolutionary history. Aiming to identify genotypes with wild and domesticated characteristics, 30 accessions of the germplasm bank of Embrapa were characterized using morphological descriptors and ISSR molecular markers.

Biological and molecular characterization of silkworm strains from the Brazilian germplasm bank of Bombyx mori

N. C. Pereira, Munhoz, R. E. F., Bignotto, T. S., Bespalhuk, R., Garay, L. B., Saez, C. R. N., Fassina, V. A., Nembri, A., and Fernandez, M. A., “Biological and molecular characterization of silkworm strains from the Brazilian germplasm bank of Bombyx mori”, vol. 12, pp. 2138-2147, 2013.

Brazil has only one public genetic pool of Bombyx mori strains, which was established in 2005 at Universidade Estadual de Maringá, Maringá, Paraná State. This genetic bank has been maintained, and the strains have been characterized using genetic and morphological tools. The quantitative and qualitative traits, directly or indirectly related to productivity, were evaluated in 14 silkworm strains. In addition to biological and productivity analyses, DNA markers related to susceptibility to the B. mori nucleopolyhedrovirus (BmNPV) were analyzed.

Determination of the genetic diversity among accessions of Senna spectabilis (canafístula) by using RAPD markers

M. F. Santos, Neto, R. B. Araújo, Nascimento, M. P. S. B. C., and Lima, P. S. C., “Determination of the genetic diversity among accessions of Senna spectabilis (canafístula) by using RAPD markers”, vol. 12, pp. 6149-6155, 2013.

Senna spectabilis (DC.) H.S. Irwin & Barneby (Fabaceae; Caesalpinioideae), commonly known as “canafístula” or “cassia”, is widely used in the semi-arid region of northeastern Brazil as a source of forage and timber. The plant presents a high nutritional content in comparison with other forage species that are native to the Brazilian Caatinga; thus, it represents a valuable resource during periods of drought. The aim of this study was to evaluate the genetic variability among eight accessions of S.
