Comparative analysis of nitrogen content and its influence on actinorhizal nodule and rhizospheric microorganism diversity in three Alnus species
Alnus spp.(alder) are typical nonleguminous nitrogen-fixing trees that have a symbiotic relationship with Frankia.To explore the differences in nitrogen-fixing microorganisms between three alders (A.cremastogyne, A.glutinosa, and A.formosana) with different chromosome ploidies, the community structure and compositional diversity of potential nitrog
