description Background and aims: The extreme conditions in the Chilean Atacama Desert are a major hurdle for the survival of any organism. Despite this, several legume populations of Geoffroea decorticans have thrived within this harsh, hostile environment for centuries. Here, we sought to determine thegenetic variability in G. decorticans populations, given its wide distribution across the Atacama  Desert, the driest and most ancient desert on Earth. The specific aims of the present study were to determinate the level of genetic diversity and assess genetic structure in eight populations of G.decorticans from Chilean Atacama Desert.M&M: Eighty-four G. decorticans individuals were selected for sampling across eight localities in Northern Chile. Five microsatellites were used to analyze genetic diversity, differentiation among populations, population structure and gene flow.Results: The majority of the analyzed populations from the Atacama Desert displayed a high genetic diversity, with the exception of PACH. G. decorticans (chañar) populations also displayed ahigh genetic differentiation and a moderate gene flow given by the natural barrier imposed by the Atacama Desert. The eight chañar populations studied were separated in groups from Northern and Southern regions. Conclusions: Microsatellites have provided valuable baseline information to understand the genetic diversity and structure of G. decorticans populations at the Atacama Desert.

Introducción y objetivos: Las condiciones extremas en el Desierto de Atacama de Chile son un obstáculo importante para la supervivencia de cualquier organismo. A pesar de esto, varias poblaciones de leguminosas de Geoffroea decorticans han prosperado en este entorno hostil y severo durante siglos. Aquí, tratamos de determinar la variabilidad genética en poblaciones de G. decorticans, dada su amplia distribución a través del Desierto de Atacama, el desierto más seco y antiguo de la Tierra. Los objetivos específicos del presente estudio fueron determinar el nivel de diversidad genética y evaluar la estructura genética en ocho poblaciones de G. decorticans del Desierto de Atacama chileno.M&M: Ochenta y cuatro individuos G. decorticans fueron seleccionados para muestreo en ocho localidades en el norte de Chile. Se utilizaron cinco microsatélites para analizar la diversidad genética, la diferenciación entre poblaciones, la estructura de la población y el flujo de genes.Resultados: La mayoría de las poblaciones analizadas del Desierto de Atacama mostraron una alta diversidad genética, con la excepción de PACH. Las poblaciones de G. decorticans (chañar) también mostraron una alta diferenciación genética y un flujo genético moderado dado por la barrera natural impuesta por el Desierto de Atacama. Las ocho poblaciones de chañar estudiadas se separaron en grupos de las regiones norte y sur.
