ISSR markers in wild species of Passiflora L. (Passifloraceae) as a tool for taxon selection in ornamental breeding

A. G. R. Sousa, Souza, M. M., Melo, C. A. F., and Sodré, G. A., ISSR markers in wild species of Passiflora L. (Passifloraceae) as a tool for taxon selection in ornamental breeding, vol. 14, pp. 18534-18545, 2015.

Inter simple sequence repeat (ISSR) molecular markers were developed and used to investigate interspecific genetic variation in 25 wild species of Passiflora preserved in an active germplasm bank (BAG-Passifloras); intraspecific diversity was also analyzed in P. cincinnata accessions. Of 31 primers tested, 20 identified polymorphic loci with a total of 331 bands, suggesting high polymorphism in the sample. Interspecific polymorphism was greater than intraspecific polymorphism. This is a common finding in studies of genetic variation using dominant markers.
