Abstract

Environmental pollution, driven by expanding industrial activities, is one of the most pressing issues today. Many fungi possess resistance mechanisms against heavy metals (HM), making them a sustainable approach for remediation processes. This study focuses on assessing HM concentrations in root samples taken from Pinus brutia in the Samsun Organized Industrial Zone (OIZ), a region heavily affected by environmental pollutants, and a nearby forested area (Adalar), while also examining the fungal diversity in the root endosphere. The fungal microbiota of the samples was determined using next-generation sequencing technology. Genera such as Aspergillus, Alternaria, Fusarium, Cladosporium, Trichoderma, Thelebolus, Plectosphaerella, Halokirschsteiniothelia, Exophiala, and Xenopolyscytalum were detected in the roots of P. brutia plants grown in the OIZ area, which is contaminated with HMs. The results indicate that higher levels of HM contamination may lead to changes in fungal diversity and an increase in the ratios of resistant taxa. This study aims to contribute to bioremediation strategies for HMs by elucidating the relationships between environmental pollutants and fungal microbiota. This research represents the first metagenomic analysis conducted in Samsun, Türkiye, to determine the impact of HMs on root fungal microbiota.

抗重金属胁迫的欧洲赤松根部真菌微生物群的元基因组特征
不断扩大的工业活动造成的环境污染是当今最紧迫的问题之一。许多真菌都具有抗重金属(HM)的机制,因此是一种可持续的补救方法。这项研究的重点是评估受环境污染物严重影响的萨姆松有组织工业区(OIZ)和附近森林地区(Adalar)的欧洲赤松根部样本中的 HM 浓度,同时研究根部内圈的真菌多样性。样本中的真菌微生物群是利用新一代测序技术测定的。在受到 HMs 污染的 OIZ 地区种植的 P. brutia 植物根部检测到了曲霉属、交替孢属、镰刀菌属、Cladosporium 菌属、毛霉属、Thelebolus 菌属、Plectosphaerella 菌属、Halokirschsteiniothelia 菌属、Exophiala 菌属和 Xenopolyscytalum 菌属。结果表明,较高水平的 HM 污染可能会导致真菌多样性的变化和抗性类群比例的增加。本研究旨在通过阐明环境污染物与真菌微生物群之间的关系,为 HMs 的生物修复策略做出贡献。这项研究是首次在土耳其萨姆松进行元基因组分析,以确定 HMs 对根部真菌微生物群的影响。

期刊介绍: Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
