Our group is interested in the study of the role of the transporters involved in maintaining the Na+ and K+ homeostasis in fungi and plants.
For a long time, we have used the yeast Saccharomyces cerevisiae as a model organism to clone and functionally characterize Na+ and K+ transporters expressing in different cellular compartments, initially, its own transporters and later, homologous transporters of others fungi and plants, from the primitive moss Physcomitrella patens to several monocot plants. One aspect that lacks so far is to know whether any of these Na+ and K+ transporters has any relevant role during symbiotic associations.
The current goal of our project is to identify the Na+ and K+ transport systems that operate during the symbiosis between plants and microorganisms associated and to determine their contribution to the mineral nutrition and salt tolerance of plants growing in saline conditions. The model organisms used are the endophyte Piriformospora indica in interaction with rice.
