Arbuscular mycorrhizal fungi colonization facilitates nitrogen uptake in cotton under nitrogen - reduction condition.

ABSTRACT: Cotton is an economically important global crop, the yield and quality of which are strongly influenced by soil nitrogen. Low nitrogen use efficiency poses an important challenge to improve cotton yield and quality. The use of arbuscular mycorrhizal fungi (AMF) has been proposed as an effective solution to this challenge. Therefore, we conducted an indoor experiment using a compartmentalized culture system with cotton as the material and established three nitrogen treatments (1 g·kg-1, 0.7 g·kg-1, and 0 g·kg-1) to investigate whether symbiosis between AMF and cotton roots could improve the nitrogen absorption capacity of cotton. The results showed that under high-nitrogen, low-nitrogen, and nitrogen- free treatments, the contributions of AMF colonization to root NO₃⁻-N and NH₄⁺-N were 5.89
