Genetic Characterization of an Endangered Chilean Endemic Species, Prosopis burkartii Munoz, Reveals its Hybrids Parentage.

ABSTRACT: The hybridization of Prosopis burkartii, a critically endangered endemic species, and the identification of its paternal species has not been genetically studied before. In this study we aimed to genetically confirm the origin of this species. To resolve the parental status of P. burkartii, inter-simple sequence repeat (ISSR), simple sequence repeats (SSR) and intron trnL molecular markers were used, and compared with Chilean species from the Algarobia and Strombocarpa sections. Out of seven ISSRs, a total of 70 polymorphic bands were produced in four species of the Strombocarpa section. An Multi-dimensional scaling (MDS) and Bayasian (STRUCTURE) analysis showed signs of introgression of genetic material in P. burkartii. Unweighted pair group method with arithmetic average (UPGMA) cluster
