Molecular and integrative physiology

Summary of the research linesfisiologia molecular integrativa

We are interested in studying the biology of nitric oxide (NO) in plants, marine microorganisms and from the rhizosphere. We have provided many evidence of physiological processes that are regulated by NO during growth and stress responses in plants, with emphasis on the signal cross-talk between NO and plant hormones. We described the first enzyme NO synthase (NOS) in the plant kingdom and we are currently focused on deciphering the role of NO in the assimilation, availability, and metabolism of nitrogen (N) in plants. Our goal is to obtain high crop yields with lower application of fertilizers and contribute to the sustainability of agriculture and the environment. We also analyze the role of NO in the plant response to UV-B. We are now working in the influence of NO in the DNA repair and the UV-B receptor stability. We are also interested in studying the functions of NO and abscisic acid (ABA) in the health of honey bees, and how to mitigate the population decline of these plant key pollinators in the world.

Influence of conserved Cys and Trp residues in the turnover of AtUVR8. Role of RCC and C27 domains in the interaction of UVR8 with COP1 and RUP1/2. NO as possible modulator of these interactions.
