Filament formation on charcoal agar by U. maydis wild type and lis1-depleted strains. Strains SG200 and its isogenic derivative SG200 Pcrg1∷lis1 were grown as described, then spotted on charcoal glucose agar. The reaction was monitored beginning at 16 h and followed for 96 h. 1, 3 = SG200; 2, 4 = SG200 Pcrg1∷lis1. Strains (1) and (2) were grown in arabinose and strains (3) and (4) on glucose before spotting on charcoal glucose agar. A. 24 h. B. 72 h. C. Magnification of spots 2 and 3 in B.
