Genetic relationship of cowpea (Vigna unguiculata) varieties from Senegal based on SSR markers

F. A. Badiane, Gowda, B. S., Cissé, N., Diouf, D., Sadio, O., and Timko, M. P., Genetic relationship of cowpea (Vigna unguiculata) varieties from Senegal based on SSR markers, vol. 11, pp. 292-304, 2012.

Genetic diversity and phylogenetic relationships among 22 local cowpea (Vigna unguiculata) varieties and inbred lines collected throughout Senegal were evaluated using simple sequence repeat molecular markers. A set of 49 primer combinations were developed from cowpea genomic/expressed sequence tags and evaluated for their ability to detect polymorphisms among the various cowpea genotypes. Forty-four primer combinations detected polymorphisms, with the remaining five primer sets failing to yield PCR amplification products.

Evaluation of genetic diversity in fig accessions by using microsatellite markers

A. D. Bdo Val, Souza, C. S., Ferreira, E. A., Salgado, S. M. L., Pasqual, M., and Cançado, G. M. A., Evaluation of genetic diversity in fig accessions by using microsatellite markers, vol. 12, pp. 1383-1391, 2013.

Fig (Ficus carica L.) is a fruit of great importance worldwide. Its propagation is carried out with stem cuttings, a procedure that favors the occurrence of synonymy among specimens. Thus, molecular markers have become an important tool for studies of DNA fingerprinting, germplasm characterization, and genetic diversity evaluation in this plant species. The aim of this study was the analysis of genetic diversity among accessions of fig and the detection of synonyms among samples using molecular markers.
