Abstract:

Nitrogen is an important element necessary for plant growth and development. The role of nitrogen in host-pathogen interactions is complex and regulated by multiple factors. In this paper, the relationship between nitrogen and plant disease development is reviewed, and the molecular mechanisms are described from the perspectives of host defense and pathogen infection. The effects of different nitrogen forms on plant disease are also compared.

摘要：

氮是植物生长发育所必需的重要元素。氮素在寄主-病原体互作中的作用十分复杂，受多重因素调控。本文综述了氮素与植物病害发生的关系，从寄主防御和病原体侵染角度论述了氮素影响植物病害发生的机制，比较了不同氮素形式对植物病害影响的差异，并对今后的研究方向进行了展望。
