Regulation of the Ald gene encoding alanine dehydrogenase and its induction of ammonium-tolerant nitrogen fixation in Paenibacillus polymyxa WLY78

Abstract Background Paenibacillus polymyxa WLY78, a Gram-positive diazotroph with plant growth promotion and phytopathogen suppression, represents a promising candidate for agricultural biofertilizers. However, its nitrogen fixation capacity is inherently limited by ammonium-mediated repression. Rec...
