| dc.description.abstract | Especies del genero Lippia, Lantana, Aloysia y Phyla tienen el potencial de convertirse en importantes especies a nivel comercial, debido a su alto contenido de aceites esenciales. Sin embargo las relaciones entre estas no han sido muy bien estudiadas desde el punto de vista taxonómico y filogenético. En ese estudio, se documentraon los niveles de diversidad genética y estructura poblaciónal en Lippia alba, L. origanoides, Phyla dulcis y Aloysia triphylla del nororiente Colombiano, las cuales difieren en su modo de propagación (natural versus propagación clonal inducida por el hombre) y su distribución (ambiente natural versus jardines). Tambien se estudiaron las relaciones genéticas entre estos cutro generos relacionados. Para este propósito, se implementaron dos regiones no codificantes del cloroplasto, el espaciador transcrito interno del ADN ribosomal (ITS) y intermicrosatelites (ISSR) como marcadores moleculares. Estos resultados sugieren que, a pesar de que estas plantas sean propagadas clonalmente, las especies de jardín de L. alba y A. triphylla mantienen niveles similares de diversidad genética comparadas con la especie distribuida naturalmente L. Origanoides. Esto sugere que las poblaciones de jardín pueden ser importantes reservorios de diversidad genética en estas especies aromaticas. Este análisis también sugiere que los generos Lippia, Phyla y Lantana están más relacionadas entre ellas que con el género Aloysia. Algumas especies de Lippia parecen estar más relacionadas a otras especies del genero Lantana que con otras especies del mismo género. Mayores análisis son necesarios en orden de establecer las relaciones entre estos generos relacionados y su naturaleza monofiletica. | |
| dc.description.abstractenglish | Species from the genera Lippia, Lantana, Aloysia and Phyla, have the potential to become commercial crops due to their essential oils. Nevertheless, the relationships among them have been poorly studied from the taxonomical and phylogenetical points of view. In this study, we document the levels of genetic diversity and population structure in Lippia alba, L. origanoides, Phyla dulcis and Aloysia triphylla from northeastern Colombia, which differ in their mode of propagation (natural versus human-induced clonal propagation) and their environments (natural versus home gardens). We also studied the genetic relationships among these four closely related genera. For these purposes, two cpDNA regions, the internal transcribed spacer of the ribosomal DNA (ITS), and ISSR (Intersimple Sequence Repeats) markers were used. The results suggest that, in spite of being mainly clonally propagated, garden populations of L. alba and A. triphylla keep genetic diversity levels that are comparable to the naturally occurring population of L. origanoides, suggesting that garden populations may be important reservoirs of genetic diversity in these aromatic species. The analyses also suggest that the genera Lippia, Phyla and Lantana are more related to each other than they are to the genus Aloysia. Some Lippia species seem to be more closely related to other species from the genus Lantana than to species from the same genus. Further analyses are needed in order to address the relationships among these closely related genera and the monophyletic nature of them | |
