FIG. 2.
Growth of wild-type (WT) C. nicotianae, pdx2 mutant strains CS2 and CS7, a pdx2 gene disruption mutant (DISR.), and pdx2 mutant strains complemented by transformation with the PDX2 gene (CS2/C and CS7/C) on minimal medium with (+pdx) and without (−pdx) pyridoxine. Fungal plugs (6 mm) were placed mycelium side down and incubated for 4 days at 28°C.
