Microbial mechanisms of rhizosphere nitrogen cycling mediated by cotton root exudates under nitrogen reduction: roles of thiamine and L-lysine

Key Points

• Nitrogen cycling mechanisms are significantly altered by root exudates from cotton plants and thiamine.
• The microbial interactions in the rhizosphere depend on the presence of specific amino acids like L-lysine.
• Assessment indicates that cotton root exudates enhance microbial activity, facilitating nitrogen availability.
• Highlighting the importance of thiamine and L-lysine, this work suggests potential agricultural improvements in nitrogen management.
