Soil Nutrients Drive Function and Composition of -Harboring Bacterial Community in Acidic Soils of Southern China.

Phosphorus (P) deficiency is an important factor that limits the agricultural production potential in acidic soils. The bacterial gene encodes non-specific acid phosphatase (ACP), which participates in the mineralization of soil organic P and is therefore important for the improvement of soil P availability. However, the function and community population of -harboring bacteria and their driving factors in acidic soil remain largely unknown.

Ammonium Alleviates Manganese Toxicity and Accumulation in Rice by Down-Regulating the Transporter Gene Through Rhizosphere Acidification.

Ammonium ( ) alleviates manganese (Mn) toxicity in various plant species, but the underlying mechanisms are still unclear. In this study, we compared the effects of and nitrate ( ) on rice ( L.) growth, accumulation and distribution of Mn, accumulation of iron (Fe), zinc (Zn) and copper (Cu), root cell wall components, and expression of Mn and Fe transporter genes.
