Cyanobacterial aggregates are important mediators of biogeochemical cycles in eutrophic lakes during cyanobacterial blooms, yet regulators of microbial activities within them are not well understood. This study revealed rDNA-based abundances strongly affected the relative activities of microbial taxa within Microcystis aggregates, as well as trade-off effects between microbial abundances and activities.

“…Thus, the significant Ksuc and catalytic inhibition of these enzymes would all lead to the attenuation of the TCA cycle and the inhibition of mitochondrial function ( Ou et al., 2020 ). Meanwhile, research on cucumber and tobacco also showed that OBZ suppresses the respiration rate ( Zhong et al., 2019 ; Zhong et al., 2020 ; Wang et al., 2022 ). Intriguingly, some NADPH-producing enzymes, such as 6-phosphogluconate dehydrogenase (6-PGD), were also modified by Ksuc under OBZ stress ( Supplementary Table 2 ).…”

“…Under environmental stress, organisms usually accumulate a large amount of ROS by performing complex physiological and biochemical processes. Several experiments have shown that OBZ increases the level of oxidative stress in organisms ( Zhong et al., 2020 ; Wang et al., 2022 ). To counteract oxidative damage caused by ROS, organisms have evolved a series of complex defence mechanisms, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and the enzymes associated with the ascorbate-glutathione (ASA-GSH) cycle.…”

Oxybenzone (OBZ), one of a broad spectrum of ultraviolet (UV) absorbents, has been proven to be harmful to both plants and animals, while omics analysis of big data at the molecular level is still lacking. Lysine succinylation (Ksuc) is an important posttranslational modification of proteins that plays a crucial role in regulating the metabolic network in organisms under stress. Here, we report the changes in intracellular Ksuc modification in plants under OBZ stress. A total of 1276 succinylated sites on 507 proteins were identified. Among these sites, 181 modified proteins were hypersulfinylated/succinylated in OBZ-stressed pakchoi leaves. Differentially succinylated proteins (DSPs) are distributed mainly in the chloroplast, cytoplasm, and mitochondria and are distributed mainly in primary metabolic pathways, such as reactive oxygen species (ROS) scavenging, stress resistance, energy generation and transfer, photosynthetic carbon fixation, glycolysis, and the tricarboxylic acid (TCA) cycle. Comprehensive analysis shows that Ksuc mainly changes the carbon flow distribution, enhances the activity of the antioxidant system, affects the biosynthesis of amino acids, and increases the modification of histones. The results of this study first showed the profiling of the Kusc map under OBZ treatment and proposed the adaptive mechanism of pakchoi in response to pollutants and other abiotic stresses at the posttranslational level, which revealed the importance of Ksuc in the regulation of various life activities and provides a reference dataset for future research on molecular function.

“…The top 10 bacterial genera with an average relative abundance > 0.7% are shown in Figure 3. The bacteria affecting soil nutrient cycling, MND1, Nitrospira, Haliangium, and Bryobacter [48,49], were more abundant in the non-rhizosphere soil than in the rhizosphere soil (p < 0.01). Among them, Bryobacter had the highest relative abundance in the NRM treatment (p < 0.01).…”

Heavy metal pollution in soil is a major global issue, and one effective method for addressing it is phytoremediation through bamboo planting. Nevertheless, there is a notable gap in our knowledge as no studies have explored the characteristics of soil organic matter (SOM) and the bacterial communities in bamboo forests during the remediation process. To bridge this knowledge gap, we conducted research to investigate the impact of different bamboo planting patterns on the SOM characteristics and microbial communities in soils contaminated with heavy metals. The contents of SOM and dissolved organic matter (DOM) in rhizosphere and non-rhizosphere soils differed significantly between monocropping and intercropping systems, with DOM accounting for only 1.7%–2.5% of SOM. Fourier transform infrared spectra showed that the contents of SOM polysaccharides C-O, carbonate C-O, aliphatic methyl, and methylene increased, while the aromatic C=C abundance decreased in the intercropping rhizosphere soil. The differences between bamboo cultivation patterns in the rhizosphere and non-rhizosphere soils were elucidated using the biomarkers, including MND1 and Nitrospira (non-rhizosphere), and Sphingomonas (rhizosphere). Heavy metals, DOM, SOM, and refined organic functional groups, especially C-O in polysaccharides and symmetric carboxylate, were the determining factors of soil bacterial communities. Compared to monocropping, intercropping increased the accumulation of Zn and Cd in bamboo shoots by 35% and 40%, respectively, and hence, intercropping soil, with a low toxicity, was suitable for bamboo shoot sprouting. Intercropping can alter the characteristics of SOM and bacterial communities and plays a vital role in phytoremediation and shoot growth in bamboo forests. Future studies on soil carbon dynamics and nutrient status during heavy metal remediation will improve our knowledge of soil transformation and its impact on soil ecosystem health and productivity.
