Our general is the characterization and identification of the biochemical and biophysical processes that regulate cell growth and cell expansion. We focus on the regulation of the transport of solutes (K+ and Na+ in particular), the establishment of ion and pH homeostasis in the plant cell and their impact on the regulation of cell volume and the traffic of membrane and their protein cargo between the different cell compartments, and the cell response to environmental changes. Our research builds on the work done by our group towards the characterization of the roles of the intracellular NHX-type of transporters. We have shown the paramount roles of the endosomal NHX5 and NHX6 in plant growth and development, and the vacuolar NHX1-NHX4 in floral development, cell expansion and ionic regulation. We apply a multidisciplinary approach to establish the functional role(s) of each intracellular NHX, combining physiology, biochemistry, genetics, genomics, vesicular membrane transport, the..
