aDLAN indicate strains constructed for this study by Dong W. Lee.bAllele numbers or designations are: arginine requirement-B (ornithine transcarbamylase), argB; biotin requirement-A, biA1; DNA methyltransferase-like-A anti-sense, non-coding transcript, tmdA; DNA methyltransferase-like-A, dmtA; methionine requirement-G1 (cystathionine-��-lyase), methG1; nitrite utilization (nitrite reductase), niiA; p-aminobenzoic acid requirement-A1, pabaA1; tryptophan requirement-C (IGP-synthetase, PRA-isomerase, anthranilate-synthetase, phosphorybosylanthranilate-isomerase), trpC801; velvet-A1, veA1; yellow conidia-A2 (laccase-I), yA2.cNote that the presence of argB+or ��argB::trpC+; and trpC+or trpC801 alleles was not determined in strains DLAN6, DLAN7 and DLAN8.dConstruction of the different plasmids is described in Materials and Methods.eFGSC, indicates strains acquired from the Fungal Genetics Stock Center, University of Kansas Medical Center, Kansas City.
