Ca gup1 Δ null mutation causes less agar invasiveness/adherence. Young cultures of C. albicans Wt, Cagup1Δ null mutant and CF-Ca001 strains were diluted and spotted onto YPD plates, which were subsequently incubated at 37°C for 5 days. Plates were further washed and the growth remains of washed plates were visualized (1-3). Longitudinal cuts of the grown cultures reveal aerial growth on the agar surface (4) and inwards agar invasion (5). The gup1Δ panel photos are representative of the results obtained with the several clones (3-5) of Cagup1Δ null mutant strain tested.
