growth of the hmgA mutant on L-tyrosine as sole carbon and energy sources is impaired. Growth on L-tyrosine is restored and production of the brown melanin pigment is eliminated when the mutant is complemented with the wild-type hmgA gene. The change in aromatic amino acids metabolism caused by the deletion of the hmgA gene function does not impair production of phenazines and biological traits connected to these secondary compounds: inhibition of fungal growth and inhibition of barley seed germination
