Presentation

Dr. Wagner L. Araújo studied Agronomy and completed his M.Sc. in Plant Physiology at the Universidade Federal de Viçosa, UFV (2006). He then moved to Germany to complete a PhD at the Max Planck Institute of Molecular Plant Physiology, Potsdam-Golm (2011). Since 2011, Dr. Araújo has worked as an Assistant Professor in the Plant Biology Department at UFV, where he teaches and supervises students in the Graduate Program in Plant Physiology at UFV. Although his research interests span plant genetics, metabolism and physiology, currently, his main projects are related to the regulation and function of alternative pathways of plant respiration, the role of organic acid metabolism in the regulation of photosynthesis and broad aspects of cyanobacterial metabolism and acclimation to stresses. He is currently a member of the Editorial Board of PLoS ONE and Frontiers in Plant Science, and he actively serves as a reviewer for a number of plant-oriented journals.

Research interest

Molecular ecophysiology, ecophysiology of photosynthesis and plant responses to abiotic stresses.

The research in my lab is currently devoted to increasing our understanding of the regulation of respiration and the alternative donation of electrons to the mitochondrial electron transfer chain as well as the linkage between hormone metabolism and primary metabolism as a whole. Our goal is to generate knowledge that might be used in biotechnological applications aiming to increase the yield, quality and safety of crops and aiming to increase the production of useful metabolic end products in both higher plants and cyanobacteria. We are currently using a range of physiological, biochemical and molecular techniques, and we are applying techniques for high-resolution metabolite profiling to answer these questions.

Motivated researchers and students willing to help us investigate these questions are welcome to contact Dr. Wagner L. Araújo.

Current projects include
  • Identification of alternative electron entry pathways into the respiratory chain of plant mitochondria
  • Understanding the role of organic acids as a component of the stomata signalling cascade: a metabolic approach
  • Metabolic and physiological determinants of differential growth in cyanobacterial strains
  • Metabolic aspects associated with cyanobacterial adaptation to high-salt environments
  • Molecular and metabolic impacts of altered levels of gibberellin in land plants
  • Ecophysiological aspects of the presence of selenium in higher plants and its interactions with metabolism
  • The metabolic importance of autophagy in Arabidopsis thaliana
  • Deciphering the importance of metabolic alterations in response to hypoxia in contrasting Eucalyptus clones
  • Examining the role of branched-chain amino acids in Arabidopsis thaliana subjected to water stress conditions
