Análisis de diversidad y estructura genética de poblaciones de Prosopis chilensis entre las provincias de Chacabuco y San Felipe de Aconcagua, usando marcadores moleculares microsatélites

Abstract

variation was found among individuals (90.78 %, P = 0.0001) rather than among populations of P. chilensis (0.16 %, P = 1.000). The level of genetic differentiation of P. chilensis was very low (FST = 0.0015) among the four populations (LAPO, HUPE, ANDE and ENDO). The STRUCTURE analysis, the Mantel test and the EMD analysis indicate that all individuals are part of a single structure, there being no evidence of barriers that generate isolation. Therefore, in the future it will be necessary to carry out more population studies of this species, in such a way to detect variation and expand the genetic groups to maintain genetic richness and biodiversity of the ecosystems. microsatellite
