Abstract

This study aimed to explore the diversity, root morphology, and colonization of arbuscular mycorrhizal fungi (AMF) associated with eight medicinal plants of the Lamiaceae family. Rhizospheric soil and root samples were collected from eight species of Lamiaceae plants for AMF analysis. The results indicate that root colonization was not directly related to the number of AMF spores in the rhizosphere. However, a significant correlation was found between the percentage of root colonization and the number of AMF species present in the individual plants. The highest percentage of colonization (86.67 ± 1.92%) and the greatest number of AMF species were observed in Micromeria fructicosa, while the lowest colonization (27.67 ± 6.22%) was recorded in Mentha arvensis. The highest spore count was recorded in Thymus vulgaris (120 ± 27.01), whereas the lowest was found in Melissa officinalis (84 ± 17.20). Among the identified AMF species, Glomus was the most dominant, representing 35.7% of all AMF species across the eight medicinal plants. The maximum AMF spore density was observed in M. fructicosa and lowest in M. arvensis. The study suggests that AMF can significantly enhance medicinal plant growth by ensuring a consistent supply of nutrients and water, thereby supporting the sustainable cultivation of medicinal plants to meet the growing demand.

探索唇形科植物中丛生菌根真菌的多样性、根部定殖和形态。
本研究旨在探索与拉米亚科八种药用植物相关的丛枝菌根真菌(AMF)的多样性、根系形态和定植情况。研究人员采集了八种拉米亚科植物的根瘤土壤和根部样本,对其进行了AMF分析。结果表明,根部定殖与根圈中的 AMF 孢子数量没有直接关系。不过,根部定殖率与单株植物中存在的 AMF 种类数量之间存在明显的相关性。果小蓟的定殖率最高(86.67 ± 1.92%),AMF 种类数量也最多,而薄荷的定殖率最低(27.67 ± 6.22%)。百里香的孢子数量最多(120 ± 27.01),而香蜂草的孢子数量最少(84 ± 17.20)。在已鉴定的 AMF 物种中,Glomus 是最主要的,占八种药用植物所有 AMF 物种的 35.7%。在果味草中观察到的 AMF 孢子密度最大,而在 arvensis 中最低。这项研究表明,AMF 可以通过确保稳定的养分和水分供应,显著促进药用植物的生长,从而支持药用植物的可持续栽培,满足日益增长的需求。

期刊介绍: The Journal of Basic Microbiology (JBM) publishes primary research papers on both procaryotic and eucaryotic microorganisms, including bacteria, archaea, fungi, algae, protozoans, phages, viruses, viroids and prions. Papers published deal with: microbial interactions (pathogenic, mutualistic, environmental), ecology, physiology, genetics and cell biology/development, new methodologies, i.e., new imaging technologies (e.g. video-fluorescence microscopy, modern TEM applications) novel molecular biology methods (e.g. PCR-based gene targeting or cassettes for cloning of GFP constructs).
