Survival strategy analysis of conidia under ammonia fungistasis. (A) Survival ability test of proteasome α7 mutants under ammonia fungistasis. WT, wild-type strain. Δg963-1 and Δg963-3, knockout mutants of gene AOL_s00054g963. (B) Survival ability test of BiP mutants under ammonia fungistasis. Δg337-3 and Δg337-9, knockout mutants of gene AOL_s00210g337. (C) Ammonia fixation pathways in fungistatic conidia. The red lines represent the glycolysis, citric acid cycle, glutamate synthesis, purine metabolism, and pyrimidine metabolism. The blue lines represent the valine, leucine, and isoleucine biosynthesis. The brown lines represent the aspartate biosynthesis and metabolism. The black lines represent serine, cysteine, and glycine metabolism and glutathione synthesis. The orange line represents phenylalanine synthesis. The green line represents ornithine and arginine synthesis. Dotted lines mean multistep reactions, and solid lines mean one-step reactions. (D to G) Test of the conidial germination rates of the wild-type strain on WA medium containing glucose, 2-oxoglutarate, pyruvate, and glutamate under the ammonia fungistasis. +, with compound; –, without compound. **, P < 0.01.
