Fig. 3From: Genome-wide identification of resistance genes and transcriptome regulation in yeast to accommodate ammonium toxicitySpot test of the 34 selected deletion mutants under different concentrations of NH4Cl. Each strain was serially diluted in a 10-fold gradient and 5 μl were spotted onto differently treated agar plates. Plates were incubated at 30 °C and photographed after 48 hBack to article page
