Dr. Agustín Zsögön is a geneticist and holds a Masters degree in Plant Physiology and Biochemistry from the University of São Paulo (2006). In 2011 he received a PhD in Plant Biology from the Australian National University, and subsequently conducted post-doctoral research at the University of Sydney and the University of São Paulo. He has been tenured as Assistant Professor of Molecular Plant Physiology at the UFV since 2015. His main research interest is the genetic and functional analysis of domestication and breeding traits in Solanaceae. His work is funded by the Royal Society and UK Research and Innovation.

Research interest

We study traits with agronomic relevance in the Solanaceae family (tomato, peppers). We use genetic variation derived from wild species or generated by molecular genetic tecniques (overexpression, interference RNA, TALENs, CRISPR/Cas9). We then assess the effects of the new alleles on plant development and agronomic performance (photosynthesis, transpiration, yield).

Current projects include

  • The genetic basis of homobaric and heterobaric leaves in tomato
  • Creation of a new model cultivar for genetic and physiological studies in Capsicum spp
  • Physiological consequences of constitutive anthocyanin production in tomato
  • The genetic and physiological basis of heterosis in tomato and Capsicum
  • Impact of florigen in water-use efficiency and drought resistance in tomato
  • Functional characterization of florigenic and anti-florigenic genes of the CETS family in tomato
  • The genetic bases of drought resistance in tomato
