| description | Background and Aims: Conservation of wild and cultivated populations in which cultivated plants originated and were domesticated is an important management action for phytogenetic resources. The aim of this study was to identify the centers of origin, domestication and genetic diversity of Spondias purpurea in Mesoamerica through phylogeographic analyses.Methods: The trnS-trnG cpDNA marker was amplified for 66 accessions from the germplasm bank of S. purpurea and sequences from Genbank published for the genus Spondias were retrieved. Sequences were grouped in 54 populations from seven biogeographic provinces based on populations sampled, and, based on the management status of the specimens, in three categories: wild, forestry management and agricultural management.Key results: In total, 38 different haplotypes were identified, 17 were exclusive for S. purpurea, 12 to S. mombin, two to S. radlkoferi, and three to S. testudinis; one grouped both S. purpurea and S. mombin, and one both S. purpurea and S. radlkoferi. Five groups of haplotypes were identified with the nested contingency analysis for all sequences of the genus, and another five for the S. purpurea sequences.Conclusions: Analyses of the results suggest the following: 1) the lack of differentiation between the lineages may be due to hybridization between species of this genus, a hypothesis yet to be tested with other molecular markers; 2) the Western region of Mexico (Jalisco, Nayarit, Michoacán) is the center of origin; 3) the center of origin as well as Guatemala are domestication centers; 4) eight populations are particularly important for germplasm conservation programs due to the haplotypes they contain and three provinces with high nucleotide diversity. |

Antecedentes y Objetivos: La identificación de poblaciones silvestres, con manejo agrícola o silvícola en los centros de origen y domesticación de plantas, es una acción importante en la conservación de los recursos fitogenéticos. Para identificar los centros de origen, domesticación y diversidad genética de Spondias purpurea en Mesoamérica se realizó un análisis filogeográfico de la especie.Métodos: Se amplificó el marcador de DNAcp trnS-trnG para 66 accesiones del banco de germoplasma de S. purpurea y se obtuvieron las secuencias publicadas en GenBank para este marcador en el género Spondias. Las secuencias se agruparon en 54 poblaciones distribuidas de siete provincias biogeográficas de Mesoamérica, de acuerdo con las localidades de las colectas, y en tres categorías: silvestre, silvícola y agrícola.Resultados clave: Se identificaron 38 haplotipos diferentes de los cuales 17 son exclusivos de S. purpurea, 12 a S. mombin, dos a S.radlkoferi y tres a S. testudinis; uno agrupa a S. purpurea y S. mombin, y uno a S. purpurea y S. radlkoferi. El análisis de contingencia anidada resultó en cinco grupos de haplotipos para las secuencias de todas las especies y otros cinco para los haplotipos de S. purpurea.Conclusiones: El análisis de los resultados sugiere lo siguiente: 1) la falta de diferenciación entre los linajes podría deberse a hibridación entre las especies del género, lo que debe comprobarse con otros marcadores moleculares; 2) el centro de origen de S. purpurea se encuentra en la región de occidente de México (Jalisco, Nayarit, Michoacán); 3) el centro de origen y la región de Guatemala son centros de domesticación de S. purpurea; 4) existen ocho poblaciones que contienen haplotipos importantes para la conservación del germoplasma y tres provincias con diversidad nucleotídica importante.
