Environmental gradients and the evolution of successional habitat specialization: a test case with 14 neotropical forest sites
(Blackwell Publishing Ltd, 2015-09)
Successional gradients are ubiquitous in nature, yet few studies have systematically examined the evolutionary origins of taxa that specialize at different successional stages. Here we quantify successional habitat ...
Micropropagación masiva de Stevia Rebaudiana Bertoni en sistemas de inmersión temporal
(Revista Cultivos Tropicales, 2015)
Stevia rebaudiana Bertoni, familia Asteraceae, es conocida como “yerba dulce” por poseer un edulcorante natural. Sus propiedades provienen de la presencia de glicósidos diterpenos denominados esteviósidos y rebaudiósidos ...
Enraizamiento de vitroplantas de membrillo (Cydonia oblonga) por medio de inmersión temporal automatizada y su aclimatación
(Revista Brasileira de Fruticultura, 2015)
El membrillo (Cydonia oblonga) es un frutal no tradicional en Costa Rica que presenta propiedades médicas y nutricionales, sin embargo la lentitud del crecimiento y enraizamiento dificulta obtener poblaciones homogéneas ...
Molecular characterization of two accessions of Cydonia oblonga
(Revista Agronomía Mesoamericana, 2015)
El objetivo de la presente investigación fue evaluar el uso del espaciador plastídico trnH-psbA y la secuencia codificante matK como posibles marcadores para la caracterización molecular de dos accesiones de membrillo (C. ...
Towards autotrophic tissue engineering: photosynthetic gene therapy for regeneration
(Biomaterials, 2016)
The use of artificial tissues in regenerative medicine is limited due to hypoxia. As a strategy to overcome this drawback, we have shown that photosynthetic biomaterials can produce and provide oxygen independently of blood ...
Scientometric analysis of Colombian research on bio-inoculants for agricultural production
(Universitas Scientiarum, 2016)
The excessive use of synthetic chemical inputs in agricultural production has led to the disruption of biogeochemical cycles. One of the alternatives that arose within the systems of sustainable agriculture was the partial ...
Identification of the agr Peptide of Listeria monocytogenes
(Frontiers in Microbiology, 2016)
Listeria monocytogenes (Lm) is an important food-borne human pathogen that is able
to strive under a wide range of environmental conditions. Its accessory gene regulator
(agr) system was shown to impact on biofilm formation ...
Molecular identification of Trichoderma spp. in garlic and onion fields and In Vitro antagonism trials on Sclerotium cepivorum
(Revista Brasileira de Ciencia do Solo, 2016)
Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby ...
Análisis prospectivo de los bioinsumos agrícolas en Colombia: una consulta a expertos
(Revista Colombiana de Biotecnología, 2015)
Productivity and sustainability of agriculture in Colombia can be influenced positively through the use of biodiversity for the production of bioinoculants. They were analyzed in the medium and long term, the future scenarios ...
Polyphenolic composition and antioxidant activity of aqueous and ethanolic extracts from Uncaria tomentosa bark and leaves
(Instituto Tecnológico de Costa Rica, 2018)
Uncaria tomentosa constitutes an important source of secondary metabolites with diverse
biological activities mainly attributed until recently to alkaloids and triterpenes. We have previously
reported for the first-time ...
