Identification and evolutionary relationships of partial gene sequences from dehydrin group in three species of cacti
(Fundacion Romulo Raggio, 2017)"Dehydrins or Group 2 Late Embryogenesis Abundant (LEA) proteins play an important role in the response and adaptation to different types of abiotic stresses such as droughts, high salinity and low temperatures. Using PCR ... -
Diversification of the kinetic properties of yeast NADP‐glutamate‐dehydrogenase isozymes proceeds independently of their evolutionary origin
(2017-04)"In the yeast Saccharomyces cerevisiae, the ScGDH1 and ScGDH3 encoded glutamate dehydrogenases (NADP‐GDHs) catalyze the synthesis of glutamate from ammonium and α‐ketoglutarate (α‐KG). Previous kinetic characterization ... -
Characterization of Candida glabrata cis-acting elements that negatively regulate transcription of EPA genes through silencing proteins
(2018-08)"La adherencia es un factor importante en la virulencia de distintos patógenos. En Candida glabrata, los genes EPA (Epithelial Adhesin) son responsables de la mayor parte de la adherencia a las células huésped y se ... -
Histone deacetylase HDA-2 regulates Trichoderma atroviride growth, conidiation, blue light perception, and oxidative stress responses
(2017-02)"Fungal blue-light photoreceptors have been proposed as integrators of light and oxidative stress. However, additional elements participating in the integrative pathway remain to be identified. In Trichoderma atroviride, ... -
Caracterización de nuevos begomovirus de un linaje que evolucionó por recombinación con un geminivirus de origen desconocido
(2015-03)"Los begomovirus (BGVs) son patógenos de plantas dicotiledóneas transmitidos por una sola especie de mosquita blanca, Bemisia tabaci, una plaga agrícola cosmopolita. Estos virus evolucionaron en Asia, de donde se diseminaron ... -
Regulación de la Expresión por estrés oxidante de EPA2 que codifica para una proteína de pared en Candida glabrata
(2015-04)"Candida glabrata ha emergido como un importante patógeno oportunista capaz de colonizar mucosas y provocar infecciones sistémicas. Tiene la capacidad para resistir niveles elevados de especies reactivas de oxígeno y es ... -
Reconstrucción de la evolución genómica de los begomovirus por medio de un enfoque multidisciplinario integrado
(2015-08)"Los geminivirus son patógenos de plantas superiores caracterizados por una cápside geminada y un genoma compuesto por una o dos moléculas circulares de ADN de cadena sencilla (ADNcs). El género Begomovirus, con más de 200 ... -
