| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | Chinchona pubescens, una planta introducida en la isla Santa Cruz (Galápagos), se ha convertido en una invasora agresiva, desplazando especies de plantas nativas. Los hongos micorrízicos arbusculares (HMA) establecen simbiosis con la mayoría de plantas vasculares, favoreciéndolas en la absorción de nutrientes y podrían ser un factor clave en la adaptación y el desarrollo de Chinchona en Galápagos. Mediante la delimitación de OTUs, usando técnicas moleculares investigamos la diversidad de HMA en C. pubescens y su posible relación en la invasión de esta planta en la isla. Basados en la similaridad de secuencias, con un umbral de 97% obtuvimos 9 OTUs y con umbral de 99% obtuvimos 18 OTUs. Todas las OTUs estuvieron distribuidas entre los órdenes Glomerales y Diversisporales. Tres OTUs fueron muy frecuentes, el resto más raras y algunas diferentes a las publicadas en el GenBank, las cuales podrían estar determinando el éxito de propagación de C. pubescens en la Isla. Aún es necesario estudiar la diversidad de HMA asociados a Chinchona en Ecuador continental, así como otros factores ecológicos para comprender mejor su propagación y planear posibles estrategias de conservación de la planta en su hábitat natural. |
| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | Chinchona pubescens, an introduced plant in the Santa Cruz Island (Galápagos), has become an aggressive invader, displacing native plant species. Arbuscular mycorrhizal fungi (HMA) establish simbiosis relationships with most arbuscular plants, favoring them in the absorption of nutrients, and these could be a key factor in the adaptation and development of Chinchona in Galapagos. Through delimitation of species using molecular techniques we investigated the diversity of AMF in C. pubescens and its posible connection in the invasión of this plant in the island. On the basis of sequence similarity, with a threshold of 97% we obtained 9 OTUs and whith a threshold of 99% we obtained 18 OTUs. All OTUs were distributed among Glomerales and Diversisporales orders. Three OTUs were very frequent, other more rare and some different to those published in GenBank, which could be determining the success of propagation of C. pubescens on the island. Further study of the diversity of AMF of Chinchona in continental Ecuador still needs to be done, as well as other ecological factors to better understand their spread and créate conservation strategies for the plant in its natural hábitat. |
