Ammonium (NH4 +) and nitrate (NO3 -) are the two main forms of inorganic nitrogen (N) that exist in soil both can be absorbed utilized by plants. As a vast crucial biome, microorganisms responsible for mediating N assimilation process enhancing use efficiency. Understanding how these assimilate different is crucial. There handful play dominant role have significant advantage abundance. However, microbial preferences ammonium or nitrate, as well differences their metabolic pathways under co-existing conditions, remain unclear. In this study, strains with advantages, Burkholderia sp. M6-3 Arthrobacter M7-15 were isolated from an acidic Chinese then incubated sources to investigate preferences. Furthermore, RNA sequencing-based transcriptome analysis was used map explore explanatory potential The results showed strain preferred utilize NH4 + while NO3 -. Although shared similar pathways, differential expression glutamine synthetase-coding gene glnA played regulating This inconsistency may attributed GlnR, global regulator utilization. research strengthens theoretical basis exploring underlying causes provided key clues screening functional ultimately enhance
