| description |
We studied the diversity and genetic structure of Oenothera drummondii Hook. (Onagraceae), a dune plant with a mixed reproductive system, across 9 populations using 10 microsatellite markers. Plant genetic diversity is governed by intrinsic factors (i.e., reproductive system and dispersal) and extrinsic factors (i.e., population f luctuations and founder effects). We found moderate to low genetic diversity, with southern populations showing lower diversity, and northern populations higher. A separate study on self-compatibility revealed higher selfing in the south and lower in the north, suggesting a latitudinal gradient that may reduce genetic diversity in southern populations. Peripheral populations showed reduced diversity and greater differentiation, likely due to increased isolation and limited gene f low. Central populations near the Texas origin exhibited the highest diversity. Populations from Baja California (O. drummondii subsp. thalassaphila) formed a genetically distinct group, suggesting a separate species. Overall, genetic patterns in O. drummondii genetic diversity ref lect historical and ecological inf luences, including mating system variation, f loral traits, and pollinator dynamics. These findings support hypotheses such as center-periphery dynamics and climate-driven historical processes (e.g., post-glacial expansion), which may shape the species’ genetic landscape and suggest possible local adaptations to environmental changes. |

(Onagraceae), planta de dunas costeras con sistema reproductivo mixto; se usaron 9 poblaciones y 10 marcadores microsatélites. La diversidad genética en plantas está inf luenciada por factores intrínsecos (dispersión y sistema reproductivo) y factores extrínsecos (f luctuaciones poblacionales y efecto fundador). Encontramos diversidad genética moderada a baja, con menor diversidad en poblaciones del sur (Ojoshal) y mayor en el norte (Bolívar). Un estudio complementario mostró mayor autocompatibilidad en Ojoshal y menor en Bolívar, sugiriendo un gradiente latitudinal con incremento de autocompatibilidad hacia el sur, con posible reducción de diversidad genética. Las poblaciones periféricas presentaron menor diversidad y mayor diferenciación, asociada a menor f lujo génico y mayor aislamiento; las poblaciones centrales, cercanas al origen de la especie en Texas, mostraron mayor diversidad. Las poblaciones de Baja California (O. drummondii subsp. thalassaphila) formaron un grupo genético distinto, que podría representar a una especie separada. En conjunto, los patrones genéticos de O. drummondii ref lejan procesos históricos y ecológicos relacionados con el sistema reproductivo, características f lorales y las dinámicas de polinización, lo cual podría significar adaptaciones locales a cambios ambientales, y patrones de distribución genética asociados con ellos, como la hipótesis de centro-periferia.Universidad Nacional Autónoma de MéxicoBiología Vegetal y EcologíaMinisterio de Economía y Competitividad (MINECO).
