Ricinuscommunisseedlings were infected with strain LBA4404, which contained the binary vector pCAMBIA1305.2 which in turn had the genetic cassette CAM 35S-fatty acid hydroxylase (FAH12) - NOS terminator. For the transformed plants a selection medium was establis hed with respective concentrations of antibiotics such as hygromycin and cefotaxime. Seeking to verify the presence of inserts in genetically modified plants, DNA wasextractedfromthenewleaves from transformed epicotyl, for further analysis by conventional PCR. For DNA analysis, two tests were carried out, in which the PCRs of thehptII and theopt-FAH12 genes were standardized for their subsequent monitoring. Finally, as a confirmatory test, the obtained amplicons were sequenced by Sanger. The previously developed protocolisa relevant step to achieve a solid molecular characterization path looking forward to get a high efficient method to transform a tropical variety of Ricinus.Ítem Determinación de parámetros cinéticos de Synechococcus sp. pcc 7002 en cultivo sumergido(2018) Colorado Hernández, Salomé; Gómez Ramírez,Luis AlejandroÍtem Articulo de datos : escarabajos coprófagos, hormigas, abejas y mariposas del jardín botánico de Medellín (Antioquia, Colombia)(Universidad EAFIT, 2018) Arrieta Echeverri, Maria clara; Bedoya Escobar, AlejandraIn this study, the entomofauna of the Botanical Garden of Medellin was characterized, for which 4 groups were selected: coprophagous beetles (Coleoptera: Scarabaeidae), diurnal butterflies (Lepidoptera: Rhopalocera), ants (Hymenoptera: Formicidae) and bees (Hymenoptera: Apiodea). Insects were collected between January 30 and February 5, 2018. Four sampling stations were established. The selected methodologies correspond to pitfall traps with copro and necro bait, Van Someren Rydon traps, manual capture through free routes with time restriction. The dataset contains 454 records distributed as 41 records of dung beetles, 127 records of ants, 72 records of butterflies and 214 records of bees. The specimens were deposited at the Francisco Luis Gallego Entomological Museum. The resource contains information on 3 species of coprophagous beetles, 16 genera of antes, 23 species/morphospecies of bees and 23 species/morphospecies of diurnal butterflies. To date, there was no information on the insect’s richness of the Botanical Garden; so, these results are considered the first georeferenced records of these taxonomic groups in the urban area of Medellin and provide the baseline for the conservation strategy of insects in this important urban ecosystem.Ítem Descripción inicial del ecosistema termo-ácido, el hidrotermal Aguas Calientes, proveniente de la cámara magmática del Nevado del Ruiz y de las comunidades que lo habitan(Universidad EAFIT, 2018) Corrales Cabra, Erika Margarita; Pinel Peláez, NicolásÍtem Clasificación de especies arbóreas según su capacidad para remover material particulado del aire en el Valle de Aburrá(Universidad EAFIT, 2018) Vásquez Bedoya, Manuela; Arroyave Maya, María del PilarAir pollution is a global problem and Colombia is not immune to this problem. Specifically, the Aburrá Valley has presented high levels of particulate matter in the air (PM) that exceed the limits established by the Colombian Air Quality Standard and by the World Health Organization (WHO). In this work, a ranking of the 100 most common trees species in Valle de Aburrá that better control the PM was made, based on its functional traits. Retrophyllum rospigliosii, Inga densiflora, Zygia longifolia, Bauhinia picta and Calliandra haematocephala were the five native species with the greatest capacity for PM removal. We suggested that those species that are above the average of 17.8 in the ranking be considered in planting plans aimed at improving the air quality within the Aburrá Valley.Ítem Diversidad y predicción del potencial funcional de las comunidades bacterianas asociadas a vitroplantas de banano cv. Williams(Universidad EAFIT, 2019) Isaza Álvarez, María Camila; Correa Álvarez, Javier; García Giraldo, GisellÍtem Evaluación de las cepas Bacillus subtilis EA-CB0015 y Bacillus amyloliquefaciens EA-CB0959 sobre cuatro hongos patógenos de arroz(Universidad EAFIT, 2019) Valencia Riascos, Luisa María; Arroyave Toro, Juan José; Villegas Escobar, ValeskaÍtem DNA barcoding of neotropical mammals : advances of Colombia at a regional scale, and the development of a reference library in the northern lowlands(Universidad EAFIT, 2019) Grisales Betancur, Valentina; Serna González, Mauricio; Díaz Nieto, Juan FernandoÍtem Actividad biológica y química en componentes de Gymnopilus subpurpuratus(Universidad EAFIT, 2019) Góez Estupiñán, Sara; Saez Vega, Alex ArmandoÍtem Inferring tumor age from multiple neutral evolutionary process(Universidad EAFIT, 2019) Londoño Muñoz, Susana; Pulido Tamayo, SergioBackground: All cancer arise as a result of a somatic mutation, several models have been developed to understand cancer, it has been seen as an evolutionary process in which somatic mutations are the pieces of the puzzle. Somatic mutation catalogue of the cancer genome has been used to reconstruct cancer phylogeny, in this case somatic mutations without selective pressure will help determine the age of a tumor. Results: Any type of mutation can have an impact on the cell, the majority of them are neutral, mutations that have less functional impact, that means less selective pressure on the tumor evolution are the ones used as temporal measurement of the tumors. A positive correlation was found between two types of measurements, which shows that an appropriate age can be extracted using both of them. Conclusion: The use of this method can be coupled with other cancer analysis, for example, along with co-occurrence and mutual exclusivity analysis could bring a better understanding of the tumor, an appropriate tumor classification and with this a more accurate clinical decision, which leads to an efective treatment.Ítem ¿Se está perdiendo nuestro conocimiento ancestral de uso de plantas de generación en generación? : un estudio aplicado al Valle de Aburrá, Colombia.(Universidad EAFIT, 2019) Mejía Calderón, Valentina; Hoyos Gómez, Saúl ErnestoÍtem Phylogenomics of the plant family Orchidaceae : solving phylogenetic ambiguities within Cymbidieae and Orchidoideae(Universidad EAFIT, 2019) Serna Sánchez, Maria Alejandra; Alvarez Yelac, Astrid Catalina; Arcila, Juliana; Arias, Tatiana; Arias Garzón, TatianaÍtem Patrones de ocupación y actividad de los roedores Simpátricos Cuniculus Paca y Dasyprocta Punctata en áreas protegidas del norte de la Cordillera Central, Colombia(Universidad EAFIT, 2019) Giraldo Amaya, Mateo; Díaz Nieto, Juan Fernando; Sánchez Giraldo, Camilo
