Brief Bio: During my undergraduate studies at National University of Rosario I became interested in plant development and biotechnology. That is why, when I saw the opportunity to join Javier Palatnik´s lab at the Institute of Molecular and Cellular Biology of Rosario, I decided to pursue a PhD degree under his direction. We aimed to to understand the mechanisms underlying plant growth through the regulatory network of microRNA miR396 and the GROWTH REGULATING FACTORS (GRFs), for which I generated and characterized plants with different levels of miR396 and GRFs. In this work published in Plant Physiology, we investigated target site variation of miR396 in eudicots and found a switch in the regulatory mechanisms of GRFs at transcriptional and post-transcriptional level.
