Colony and hyphal characteristicsa of wild type, and AnugmA▵ strains complemented with wild type AfUgmA, single residue AfUgmA mutants and deletion strains grown on CM.

a Values are presented as mean ± standard error. Statistical significance of the mean values was compared using a Kruskal–Wallis test, and shown for each characteristic to be significantly different at Pb At least 4 colonies per strain were counted. Spores of wild type and mutated strains were streaked on CM and incubated for 3 d at 28°C to give isolated colonies.c The diameter of ten colonies/strain was measured using a dissection microscope.d Hyphal width was measured at septa. Basal cell length was between adjacent septa for n = 25 measurements per strain.
