Signaling Mechanisms in Plants
The research lines of the group are focused on the study of second lipid messengers, gasotransmisors and the regulation of ion channels as intermediaries in signal transduction processes, among others. These processes are mainly studied in two experimental systems:
- Plant-pathogen interaction: involves the role of different phospholipase C isoenzymas in the perception of pathogens and the induction of defense responses, in order to contribute to a deeper understanding of the resistance/susceptibility mechanisms of plants; and
- Regulation of stomatal pore closure: refers to the role of hydrogen sulfide (H2S). This is a low molecular weight gas, belonging to the group of gasotransmisors. This line focuses on the role of H2S in signaling pathways that regulate stomatal closure in response to different stimuli.

Ana’s interest focuses on the study of second lipid messengers in signal transduction processes in plants. It focuses on the role of different phospholipase C isoenzymas in the perception of pathogens and the induction of defense responses, in order to contribute to a deeper understanding of the resistance/susceptibility mechanisms of plants.
Carlos studies the role of small gaseous molecules known as gastransmitters, and their mechanisms of action, in signaling processes in plants. He focuses on the regulation of the stomatal aperture, microscopic structures that act as valves controlling CO2 uptake for photosynthesis and the transpirational H2O loss.
Denise is interested in studying the role of H2S in the regulation of pathogen-mediated stomatal closure.
Paula studies the participation of H2S and phospholipase regulation in the modulation of stomatic movement.
Patricia studies the involvement of hydrogen sulfide (H2S) in signaling processes triggered by blue light in plants.
Rosario is interested in studying the role of mitochondrial hydrogen sulfide (H2S) in the modulation of the opening and closing of stomata.
Luciana is interested in studying the role of post-translational modifications in the phospholipase C2 of Arabidopsis and the possible regulatory interactors of its activity.
Enzo is interested in knocking out by gene editing in tomato, to evaluate the role of the phospholipase C gene family, with special emphasis on plant-pathogen interaction.
Juan Martín is studying the role of proteins that bind cell membranes of different organelles with the plasma membrane (contact-sites) using Arabidopsis as an experimental model.
