Redes regulatorias en el control de desarrollo vegetal y la respuesta al ambiente

Plant Genomics and Systems Biology Laboratory (PlantomicsLab)

El interés de nuestro grupo es identificar redes regulatorias génicas que controlan la respuesta de las plantas a señales medioambientales y su impacto en el desarrollo vegetal. Estamos particularmente interesados en estudiar el rol de estas redes en raíces de plantas, ya que la raíz es un órgano altamente plástico y clave en la adquisición de nutrientes y la interacción con otros organismos en el suelo. De manera de llevar a cabo nuestros objetivos de investigación, utilizamos una combinación de aproximaciones genéticas, genómicas y de biología de sistemas en la planta modelo Arabidopsis thaliana y en plantas de la familia de las Solanáceas. Nuestras líneas actuales de investigación incluyen: 1) la identificación de GRNs controladas por RNAs pequeños en el desarrollo y la respuesta a déficit nutricional en raíces de Arabidopsis, 2) Interacción entre vías de señalización de hormonas y nutrientes en el remodelamiento de la raíz, 3) Mecanismos de comunicación entre plantas y otros organismos y su rol en la promoción de resistencia vegetal al estrés abiótico

Dr. Vidal is a biochemist and obtained her PhD in Biological Sciences from P. Universidad Católica de Chile (PUC), working with Dr. Rodrigo A. Gutiérrez. Her main expertise involves the use of systems biology and functional genomics approaches to address and produce testable biological hypotheses. Her Doctoral work involved the use of high-throughput sequencing technologies and data analysis to identify the small RNA (sRNA) and mRNA components of the transcriptome in response to nitrate in Arabidopsis thaliana. She received training in these subjects in Dr. Gloria Coruzzi’s Laboratory in New York University -a leader in plant systems biology- and Dr. W. Richard Mc Combie’s Laboratory in Cold Spring Harbor -one of the pioneers in high throughput sequencing-, where she acquired a strong expertise in identifying and quantifying the expression of sRNAs and in sRNA target identification and experimental validation. Her work in this subject produced publications of considerable impact.

After finishing her PhD, she worked as adjunct researcher of the Department of Molecular Genetics and Microbiology at PUC, supported by an Academy Insertion fellowship (Proyecto Bicentenario de Ciencia y Tecnología). As associate researcher, she was involved in several projects most of them related to the identification of Nitrogen-controlled regulatory networks, which have produced many ISI publications that have a remarkable acceptation in the field, being cited numerous times. Dr. Vidal participated as Doctoral student and Postdoctoral fellow of the Millennium Nucleus in Plant Functional Genomics and is now Associated Researcher of the Millennium Institute in Integrative Biology iBio.

Dr. Vidal started her laboratory as an assistant professor at the Center of Genomics and Bioinformatics (CGB) at Universidad Mayor in June 2016. Her research interest focuses on the identification of regulatory networks controlling plant responses to the environment.
