Fig. 2From: Expanding the toolbox: another auxotrophic marker for targeted gene integrations in Trichoderma reeseiPhenotype characterization of the auxotrophic strains. The indicated strains were cultivated on minimal medium plates supplemented with 5Â mM uridine, 2.5Â mM arginine, and 4Â mM histidine (MMâ +), and on comparable plates lacking one of the three supplements (-Uri, -His, -Arg), and on minimal plates without any supplements (MM-)Back to article page
