The strains were grown on solid rich (YPD), low-nitrogen (SLAD) or low-carbohydrate (SCLD) media.
The presence of pseudohyphal growth (PH) is denoted: +. For invasive growth (IG) the patterns are divided into four groups according to the intensity: −, no invasive growth; +, moderate invasive growth; ++, intermediate invasive growth; +++, enhanced invasive growth.
