丛枝菌根真菌与植物硫素营养研究进展

Research progress of arbuscular mycorrhizal fungi and plant sulfur nutrition

摘要:

丛枝菌根真菌是土壤微生物群落的重要组成部分，是最常见的地下共生菌，对植物和土壤具有多种有益作用。本文阐述了近年来丛枝菌根真菌对植物吸收土壤硫素的最新进展，在目前耕地缺硫状况下，着重分析了丛枝菌根真菌改善植物硫素营养以及丛枝菌根真菌利用硫素的分子调控机制，总结了影响菌根硫代谢的因素，并指出该研究方向仍存在的一些问题以及未来的研究侧重点。

Abstract:

Arbuscular mycorrhizal fungi are important components of soil microbial community, which have a variety of beneficial effects on plants and soil. In order to further understand this common underground symbiotic microorganism and investigate its effect on sulfur uptake and utilization of plant, we reviewed the latest research progress. In this paper, the molecular regulation mechanism of plant sulfur nutrition improved by arbuscular mycorrhizal fungi was emphatically analyzed and the factors influencing the sulfur metabolism of mycorrhizal plant were also summarized. Finally, some problems that still exist in this research direction and the focus of future research were also proposed.

Key words:arbuscular mycorrhizal fungi, sulfur nutrition, regulation mechanism
