13. Analysis of ferrichrome biosynthesis in the phytopathogenic fungus Ustilago maydis: cloning of an ornithine-N5-oxygenase gene.
By using a non-enterobactin-producing enb-7 mutant of Salmonella typhimurium LT2 as a biological indicator, a novel screening method was developed for identifying mutants of Ustilago maydis defective in the biosynthesis of the siderophores ferrichrome and ferrichrome A. Two classes of siderophore mutations, both recessive, were isolated after mutagenesis of
