摘要
丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)广泛存在于土壤中,可以与陆地植物形成有益的共生关系。硫氧化细菌(sulfur oxidizing bacteria,SOB)是氧化土壤中还原性硫和单质硫的重要微生物,对增加土壤肥力、降低土壤p H和促进植物生长具有重要作用。目前,国内外对这两种有益微生物之间相互合作的研究较少。本文简述了AMF和SOB对土壤及植物的影响,包括对土壤的改良、植物的生长和植物矿质营养的运输,总结了菌根共生和微生物作用对AMF中矿物质转运蛋白的影响,归纳了SOB的三个重要硫氧化途径。通过了解AMF和SOB近几年的研究现状,以及AMF与其他微生物互作关系的研究进展,我们对AMF与SOB之间的可能互作关系进行了探讨,并对其进一步研究提出展望,为AMF和SOB作为土壤联合接种菌剂、改良土壤和改善植物营养提供了理论基础。
Arbuscular mycorrhizal fungi(AMF)widely exist in soil and can form beneficial symbiotic relationships with terrestrial plants.Sulfur oxidizing bacteria(SOB)are important group of bacteria for the oxidation of reducible sulfur and elemental sulfur in soil.SOB plays an important role in increasing soil fertility,reducing soil p H,and promoting plant growth.However,few studies have examined the cooperation between these two beneficial microorganisms.Here,we examined the effects of AMF and SOB on soil and plants,including soil quality improvement,plant growth,and transportation of mineral nutrients.Moreover,the effects of mycorrhizal symbiosis and microbial function on mineral transporters in AMF and three important sulfur oxidation pathways of SOB were also summarized.Based on the understanding the research status of AMF and SOB in recent years and the research progress of the interaction between AMF and other microorganisms,we analyzed the possible interaction between AMF and SOB and also gave prospects for further studies.This review provides a theoretical basis for using AMF and SOB as soil inoculants to improve soil and plant nutrition.
