Signalling Mechanisms in Plants Lab ahead by Dr. Ana M. Laxalt
The group's research lines focus on the study of lipid second messengers, gasotransmitters and the regulation of ion channels as intermediaries in signal transduction processes in plants, among others. These processes are studied, mainly, in two experimental systems:

Plant-pathogen interaction: involves the role of the different isoenzymes of phospholipase C in the perception of pathogens and the induction of defence responses, to contribute to a deeper knowledge of the resistance/susceptibility mechanisms of plants; and
The regulation of stomatal pore: refers to the role of hydrogen sulfur (H2S). This is a low molecular weight gas, belonging to the group of gas transmitters. This line focuses on the role of H2S in the signalling pathways that regulate stomatal closure in response to different stimuli.

Research focus

We studied stomata regulation upon different stimuli through microscopy (fluorescence and optical), biosensors, molecular biology and biochemistry approximation.
