“…Studies have shown that glucose is utilized as a substrate for glycolysis and is beneficial for improving plant metabolism and stress resistance (Du et al, 2022). In our study, glycolysis was active during recovery, yet the amount of glucose increased, which may be due to the increase in photosynthesis during recovery.…”

The increase in UV-B radiation at the Earth’s surface due to the depletion of the stratospheric ozone layer is a notable facet of contemporary climate change patterns. The macroalgae inhabiting the intertidal zone exhibit a diverse array of adaptive strategies to cope with dramatic environmental changes. In this study, we integrated physiological, transcriptomic and metabolomic data from energy metabolism perspective to elucidate the responses and recovery mechanism of N. haitanensis to UV-B radiation exposure. UV-B radiation has a harmful impact on the photosynthetic performance of N. haitanensis. However, an increase in photosynthetic performance and upregulated expression of genes related to photosynthesis were observed during recovery, suggesting that the effect of UV-B on N. haitanensis was dynamic photoinhibition. Recovery experiments revealed that most genes and metabolites related to glycolysis were significantly upregulated, suggesting that glycolysis was activated to promote energy production. In addition, the TCA cycle was also activated, as evidenced by the increase in key substances and the upregulated expression of key enzyme-encoding genes during recovery. Correspondingly, ATP was also abundantly accumulated. These results suggested that the TCA cycle provided ATP for N. haitanensis to repair UV-B damage. Meanwhile, amino acid metabolism was enhanced during recovery as a source of intermediates for the TCA cycle. Therefore, photosynthesis, glycolysis, the TCA cycle, and amino acid metabolism synergistically cooperate to provide material and energy for recovery after UV-B radiation. This study is important for understanding the adaptive strategies of intertidal macroalgae in response to UV-B radiation.

Heavy chromium pollution is a global sticky problem. In this study, an built-in proteomic and metabolomic method used to be used to look at the possible organic toxicity of Cr-contaminated answer based totally on an publicity scan with Penicillium janthinellum P1. The results showed that the high-Cr exposures resulted in cell injuries and signaling disturbances in P. janthinellum P1. Furthermore, Cr-contaminated answer triggered an amplify in glutamine and a sizable minimize in dimethylglycine, betaine and taurine, suggesting that the osmoregulatory metabolism of the P. janthinellum may additionally have been disturbed. The alteration of ATPase and mitochondrial associated proteins, combined with the upregulation of amino acids and carbohydrates, revealed that Cr contamination may disrupt the energy metabolism system. In addition, the secretory effects were confirmed by the upregulation of cytochrome P450 and deoxypodophyllotoxin, and the downregulation of penicillopepsin via proteomics. Therefore, dimethylglycine, glutamine, aspartate and cytochrome P450, all with remarkably alteration, were supposed to be selected as potential biomarkers of Cr contamination. This work assume to furnished new perception into the proteomic and metabolic toxicity of excessive Cr-contaminated area of interest in filamentous fungi, highlighted the mechanisms underlying toxicity and extended our knowledge of multi-omics jointly.

Cucumber wilt disease, caused by Fusarium oxysporum f. sp. cucumerinum (FOC), is a major threat to cucumber production, especially in greenhouses. This study used a fermentation product derived from a new strain of Streptomyces rochei (G-6) to investigate the potential for biocontrol of cucumber wilt disease and the effect on promoting cucumber growth. In the first experiment, the inhibitory effect of S. rochei G-6 fermentation product (SGFP) on FOC growth was evaluated, then the effect of SGFP on wilt incidence and severity, as well as cucumber growth, antioxidant system, and soil nutrient conversion capacity were investigated. The results showed that SGFP inhibited FOC growth by 85.3% in the antimicrobial experiment. In the potting experiment, the incidence rate in the FOC group reached 88.7%, but it was only 56.0% in the SGFP1 group and 64.7% in the SGFP2 group, indicating the efficient inhibitory effect of SGFP on cucumber wilt, with the biocontrol effect of SGFP1 being higher than that of SGFP2. In addition, the disease index decreased significantly (p < 0.05) in both SGFP treatments, which was significantly (p < 0.05) lower in the SGFP1 group than in the SGFP2 group, indicating that pre-treatment was better than post-treatment in reducing the disease severity. In addition, SGFP promoted the growth of cucumber seedlings, as indicated by indicators related to the growth of aboveground and underground parts. Furthermore, the activities of antioxidant enzymes (superoxide dismutase, peroxidase, and catalase) in the cucumber seedlings increased after SGFP treatment and the malondialdehyde level was decreased, indicating a reduction in oxidative stress. SGFP also improved the soil nutrient conversion capacity by increasing the activities of urease, phosphatase, and sucrase, which may enhance nutrient uptake by cucumber seedling. The findings of this study suggest that SGFP is an effective biocontrol agent against cucumber wilt and also promotes cucumber growth by regulating the antioxidant system and soil environment, and its application is a promising solution to reduce wilt incidence in cucumber production.
