Aspergillus nidulans is a genetic model for studying polarised cell growth and long-distance transport. Hyphal tip cells grow exclusively by apical extension, leading to tubular multinucleated cells where intracellular traffic is tailored to the large distances that exist between apical and distal regions of the cytosol, or between the different nuclei of the cell. We use a combination of formal Genetics with Molecular and Cellular Biology to understand intracellular traffic, including the mechanisms by which environmental signals are transduced to the different nuclei of the cell to ensure coordinated transcriptional responses. The Aspergillus research unit is led by Dr. Eduardo A. Espeso (acting as coordinator), Dr. Mario Pinar and Dr. Miguel A. Peñalva.
