Estimation of genetic variation in closely related cycad species in Ceratozamia (Zamiaceae: Cycadales) using RAPDs markers
The Ceratozamia norstogii complex from Southern Mexico is made up of four closely related taxa and occurs in similar habitats (Quercus forest). All have linear-lanceolate leaflets with great similarity between them, especially in juvenile stages, but differentiate with age. There has been debate reg...

| description |
The Ceratozamia norstogii complex from Southern Mexico is made up of four closely related taxa and occurs in similar habitats (Quercus forest). All have linear-lanceolate leaflets with great similarity between them, especially in juvenile stages, but differentiate with age. There has been debate regarding delimitation of species due to character loss in herbarium specimens. The aim of this study was to determine the genetic variation, and to measure genetic similarity between the four taxa. We studied populations in Cintalapa (Chiapas) for C. alvarezii and C. norstogii; the Sierra Atravesada (Oaxaca) for C. chimalapensis, and Villa Flores (Chiapas) for C. mirandae. One population for each taxon was sampled (only one population is known for C. alvarezii) 11-15 randomly chosen adult individuals were sampled. Twenty-eight primers were tested of which five were polymorphic using the RAPD’S technique. The data were analyzed using Bayesian methods. Results revealed low genetic diversity, and a differentiation was found between species, suggesting a recent divergence. A previous morphological and anatomical study on the complex has found the taxa to be distinct. However, the results of this study have shown that the C. norstogii species complex is in a divergence process, probably through genetic drift and founder effects. |

Todos tienen folíolos linear-lanceolados con gran similitud entre ellos, sobre todo en las etapas juveniles, pero se diferencian con la edad. Ha habido un debate en relación con la delimitación de especies debido a la pérdida de caracteres en especímenes de herbario. Los objetivos de este estudio son determinar la variación genética y medir la similitud genética entre los cuatro taxones en el complejo. Las poblaciones estudiadas están en; Cintalapa, Chiapas para C. alvarezii y C. norstogii, la Sierra Atravesada, Oaxaca para C. chimalapensis y Villa Flores, Chiapas para C. mirandae. Se tomaron muestras de una población de cada taxón (sólo una población es conocida para C. alvarezii) 11-15 individuos adultos elegidos al azar fueron muestreados. Veintiocho primers fueron probados, de los cuales cinco fueron polimórficos mediante la técnica RAPD's. Los datos fueron analizados utilizando métodos bayesianos. Los resultados revelaron baja diversidad genética y la diferenciación encontrada entre las especies sugiere una divergencia reciente. Un estudio morfológico y anatómico anterior en el complejo encontró que los taxa son distintos. Sin embargo, los resultados del presente estudio han demostrado que el complejo C. norstogii aun se encuentra en un proceso de divergencia, probablemente a través de deriva genética y efectos de fundador.Universidad de Costa Rica2017-03-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/1526610.15517/rbt.v65i1.15266Revista de Biología Tropical; Vol. 65 No. 1 (2017): Volume 65 – Regular number 1 – March 2017; 305–319Revista de Biología Tropical; Vol. 65 Núm. 1 (2017): Volumen 65 – Número regular 1 – Marzo 2017; 305–319Revista Biología Tropical; Vol. 65 N.º 1 (2017): Volumen 65 – Número regular 1 – Marzo 2017; 305–3192215-20750034-774410.15517/rbt.v65i1reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/rbt/article/view/15266/28218https://revistas.ucr.ac.cr/index.php/rbt/article/view/15266/28219Derechos de autor 2017 Revista de Biología Tropicalhttp://creativecommons.org/licenses/by/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-06-09T18:02:38Zoai:portal.ucr.ac.cr:article/15266Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:16:35.349Portal de Revistas UCR - Universidad de Costa Ricafalse |
