* ''' Polyamines in stress tolerance.''' Polyamines are small aliphatic compounds present in all living organisms. Polyamine biosynthesis is an evolutionary conserved pathway under an apparent purifying selection. Even though their essential role in stress tolerance is genetically demonstrated, molecular and signalling mechanisms underlying cell protection are relatively obscure. I am interested in gaining insight into the role of polyamines in stress tolerance and signalling (including developmental pathways) using advanced genetic approaches and exploring direct applications of polyamine content regulation (by means of natural variation) in crop breeding.

Research interests

  • Plant-Environment Interactions. I am interested in studying the adaptation of plants to local environments using population genetics. My research includes abiotic and biotic interactions from a molecular, genetic and evolutionary perspective, mainly in model species with a potential application in crops. Press release 2010

  • Polyamines in stress and development. Polyamines are small aliphatic compounds present in all living organisms. Polyamine biosynthesis is an evolutionary conserved pathway under an apparent purifying selection. Even though their essential role in stress tolerance is genetically demonstrated, molecular and signalling mechanisms underlying cell protection are relatively obscure. I am interested in gaining insight into the role of polyamines in stress tolerance and signalling (including developmental pathways) using advanced genetic approaches and exploring direct applications of polyamine content regulation (by means of natural variation) in crop breeding.
