“…For instance, chloroplast distribution is used for evaluating light stress ( Kasahara et al, 2002 ) or chemical stress ( Samardakiewicz et al, 2015 ), and is also related to ROS ( Samardakiewicz et al, 2015 ). In addition, MP exposure results in altered activities of antioxidant enzymes ( Jiang et al, 2019 ; Yang et al, 2022 ). Previous studies have also reported that oxidative damage decreases with a decrease in the MP size ( Jiang et al, 2019 ; Li et al, 2020 ).…”

“…The V4 hypervariable region of the 18S rRNA gene was amplified using the primer set 547F (5′‐CCAGCASCYGCGGTAATTCC‐3′) and V4R (5′‐ACTTTCGTTCTTGATYRA‐3′) (Stoeck et al, 2010). The primer set 338F/806R is commonly used in scientific publications of aqueous ecosystems (J. Li et al, 2019; Shi et al, 2019; Yang et al, 2022; Z. Zhang et al, 2023) and have been reported to show a relatively high sensitivity for bacteria (Q. Zeng & An, 2021). Similarly, The primer set 338F/806R is commonly used in scientific publications of aqueous ecosystems (Ma et al, 2022; She et al, 2023; Zhi et al, 2023) and have been reported to show a relatively high sensitivity for microeukaryotes (Huws et al, 2007; Stoeck et al, 2010).…”

“…Three DNA extracts from three sediment aliquots (sediment sample was reduced using quartering method) were pooled to obtain a representative sample of sediment core and the concentrations of DNA extracts were determined using a NanoDrop One C spectrophotometer (Thermo Scientific, WI). The V3-V4 hypervariable region of the 16S rRNA gene was amplified using the primer set 338F (5 0 -ACTCCTACGGGAGGCAG-CAG-3 0 ) and 806R (5 0 -GGACTACHVGGGTWTCTAAT-3 0 ) (Yang et al, 2022). The V4 hypervariable region of the 18S rRNA gene was amplified using the primer set 547F (5 0 -CCAGCASCYGCGGTAATTCC-3 0 ) and V4R (5 0 -ACTTTCGTTCTTGATYRA-3 0 ) (Stoeck et al, 2010).…”

Phylogenetic distance–decay patterns are not explained by local community assembly processes in freshwater lake microbial communities

While water and sediment microbial communities exhibit pronounced spatio‐temporal patterns in freshwater lakes, the underlying drivers are yet poorly understood. Here, we evaluated the importance of spatial and temporal variation in abiotic environmental factors for bacterial and microeukaryotic community assembly and distance–decay relationships in water and sediment niches in Hongze Lake. By sampling across the whole lake during both Autumn and Spring sampling time points, we show that only bacterial sediment communities were governed by deterministic community assembly processes due to abiotic environmental drivers. Nevertheless, consistent distance–decay relationships were found with both bacterial and microeukaryotic communities, which were relatively stable with both sampling time points. Our results suggest that spatio‐temporal variation in environmental factors was important in explaining mainly bacterial community assembly in the sediment, possibly due lesser disturbance. However, clear distance–decay patterns emerged also when the community assembly was stochastic. Together, these results suggest that abiotic environmental factors do not clearly drive the spatial structuring of lake microbial communities, highlighting the need to understand the role of other potential drivers, such as spatial heterogeneity and biotic species interactions.

“…High concentrations of HMs and toxic substances serve as a source of energy and nutrition for Proteobacteria [74]. Thus, an increase in the relative abundance of Proteobacteria in contaminated soil might be helpful in maintaining a stable nutritional level for the growth of L. esculentum and may improve the ability of L. esculentum to resist Cd toxicity [75]. 5 below shows the bacterial community composition at the phylum level.…”

The Effects of Coexisting Elements (Zn and Ni) on Cd Accumulation and Rhizosphere Bacterial Community in the Soil-Tomato System

The increasing cadmium (Cd) levels in agricultural soils have become a worldwide concern for food crop security. Cd accumulation in the soil-plant system is closely related to other coexisting factors. In this study, the effects of different levels of Zn or Ni on Cd accumulation in tomato plants and on the rhizosphere soil bacterial community structure were analyzed by coupling pot experiments with high-throughput sequencing. The results demonstrated that tomato plants (Lycopersicon esculentum) in Zn-Cd and Ni-Cd co-contaminated soils exhibited lower relative growth rates. Co-contamination at low levels tended to reduce the bioaccumulation of heavy metals in the roots of plants, whereas increased contaminant concentrations produced the opposite effect. In the presence of 200 mg/kg Zn or 20 mg/kg Ni, the biomass of plant roots increased by 4.95–23.16% and the Cd content of the plant roots decreased by 17.36–68.93% due to the antagonistic effects between Cd and Zn/Ni. In addition, the richness and diversity of the bacterial community were significantly altered under HMs co-contamination, and the number of special bacteria was positively correlated with the level of heavy metals in the rhizosphere soil. The relative abundance of Proteobacteria increased and that of Actinobacteria decreased in soils with low levels of heavy metals. This may improve the tolerance of plant roots to heavy metals and reduce the accumulation of Cd in plant roots. These findings highlight the important role of coexisting elements in the inhibition of Cd accumulation in tomatoes and offer important information for the production of safe crops.
