Summary: The study found that in oysters from an urban estuary in Northeast Brazil, the bioaccumulation of Hg was higher during the rainy season, and changes in biomarkers indicated elevated stresses for organisms in the inner portion of the estuary. However, no correlation was observed between Hg in sediment/oyster and biomarker results.

Summary: In this study, a tau-like glutathione transferase family gene named GmGSTU23 was identified in soybean, which showed a concentration-time-specific expression pattern in response to salt stress. Transgenic lines with GmGSTU23 displayed enhanced salt tolerance, root length, and fresh weight compared to the wild type. Changes in glutathione pools and associated enzyme activity were observed, indicating that GmGSTU23 enhances the activity of glutathione transferase to scavenge reactive oxygen species and glutathione, thereby conferring enhanced tolerance to salt stress in plants.

Summary: This study measured the differential expression of antioxidant enzymes in response to radiation-induced oxidative stress after administration of C. borivilianum root extract. The results indicate a significant increase in glutathione levels and the activity of glutathione-related antioxidant enzymes in mice treated with CRE and CRE-AgNPs. The activity of catalase and superoxide dismutase was also increased in the CRE-AgNPs pretreated irradiated groups.

Summary: GST enzyme is abundant and plays a detoxifying function in various species, particularly in tissues exposed to xenobiotics. This study partially purified GST enzyme from mallow seed and determined its kinetic parameters. It also investigated the inhibitory effects of Cd+ 2, Ag+, Zn+ 2, and Fe+ 3 heavy metals on mallow seed GST enzyme, finding that each metal showed micromolar inhibitory effects with calculated IC50 values.

Summary: ZmGST26 was found to be downregulated in maize under drought stress. Overexpression of ZmGST26 in Arabidopsis resulted in increased sensitivity to drought stress and ABA, as well as inhibited ABA-mediated stomatal closure. ZmGST26 overexpression decreased the resistance of Arabidopsis to drought stress and led to the accumulation of reactive oxygen species.

Summary: Dopamine transporter knockout (DAT-KO) rats are a valuable rodent model for studying the effects of excessive dopamine accumulation on neurons. These animals exhibit hyperactivity, stereotypy, cognitive deficits, and impairments in behavioral and biochemical indicators. The current study analyzed the activity levels of key antioxidant systems in DAT-deficient rats and demonstrated their role in the regulation of oxidative stress. Changes in physiological and biochemical parameters were observed at 1.5 months of postnatal life, highlighting the importance of these systems in DAT-KO rats.

Summary: The study found that lower concentrations of methomyl had no effect on antioxidant levels in the testis of Nile tilapia, while higher concentrations significantly influenced these antioxidants. Recovery tests showed that oxidative damage caused by lower concentrations of methomyl was reversible, whereas damage from higher concentrations was irreversible within 18 days.

Summary: GSTs are versatile proteins that play important roles in detoxification and cellular nitric oxide metabolism. They have the ability to convert organic nitrates into nitric oxide, thereby regulating vasodilation. GSTs are also considered suitable targets for pharmaceutical development, particularly in the field of anti-cancer drugs.

Summary: Some members of Acanthamoeba are facultative pathogens that can infect the cornea, causing Acanthamoeba keratitis. During encystation, there is an upregulation of glutathione S-transferase (GST) genes, which play a role in maintaining redox balance. Inhibiting GST with ethacrynic acid decreases cell viability by 70%. Targeting GST and associated processes could be a potential treatment strategy to reduce relapses of Acanthamoeba infection.

Summary: Isoe center dot tes cangae is a critically endangered submerged quillwort endemic from Amazon ferruginous outcrops fields in north Brazil, and its conservation is highly dependent on the proper management of light irradiance in ex situ and in situ cultivation. Our study analyzed the relationship between light irradiance and species morphological and physiological traits by comparing the growth and photosynthesis of I. cangae under different irradiance levels. The results showed that high irradiance impaired growth and photosynthesis, emphasizing the importance of controlling light intensity for this shade-tolerant species.

Summary: The study found that using permeable membranes and 10 g L-1 sucrose can optimize photosynthesis, growth, and development of Ananas comosus in both in vitro and ex vitro conditions. This resulted in longer shoot lengths, increased leaf area, enhanced photosynthetic capacity, chlorophyll contents, and carotenoids. Therefore, for the in vitro culture and acclimatization of A. comosus, the use of permeable membranes and 10 g L-1 sucrose can benefit plant growth and enhance adaptability.

Summary: This study evaluated the response of tomato plants to water scarcity by analyzing changes in leaf reflectance and identifying spectral reflectance indices (SRIs) for the early detection of drought stress. The researchers found 12 SRIs that showed significant differences between treatments, with 6 of them already significantly different within 7 or 9 days after the experiment started. These findings suggest that these SRIs could be used as promising proxies for the early detection of invisible responses to drought onset.

Summary: This study investigated whether the volatile organic compound 1-octen-3-ol is involved in the mechanisms of ectomycorrhizal (ECM) fungi that modulate below and aboveground communities. Through three in vitro assays, it was found that 1-octen-3-ol had dose-dependent effects on mycelium growth of three ECM species, inhibited seed germination, and influenced host plant traits. These findings suggest that 1-octen-3-ol may mediate changes in below and aboveground communities by regulating the release of ECM fungal volatiles.

Summary: This study evaluated the effects of sealing lids and culture media on in vitro seedling growth of Dalbergia nigra, with a focus on ethylene accumulation and changes in the protein profile. The results showed that sealing lids with microporous membranes promoted better seed germination and improved seedling development. The absence of microporous membranes in the culture media led to increased CO2 levels and leaf abscission. Furthermore, the accumulation of ethylene and proteins was influenced by both the culture media and the presence of microporous membranes.

Summary: Considering the increasing frequency and duration of drought events caused by climate change, enhancing plant drought tolerance is a priority. The search for plant growth promoting rhizobacteria (PGPR) that can improve plant drought tolerance has been ongoing for a long time, but the results have been inconsistent. In this study, we summarize the mechanisms of PGPR that enhance plant drought tolerance, identify the issues in current PGPR isolation and selection methods, and discuss the key points for defining new strategies to obtain optimal PGPR for improving plant drought tolerance. Drought and host genotype affect rhizo-communities, and host-mediated selection strategies can be used to obtain a drought-adapted rhizomicrobiome that can serve as a source for PGPR isolation. Alternatively, an integrated omics-level analysis can enhance our understanding of the mechanisms of rhizomicrobiome construction, allowing for the design of a targeted approach focused on key plant growth-promoting traits. New strategies for building PGPR consortia to enhance plant drought tolerance are also suggested.

Summary: This study evaluated the effects of different concentrations of iron(II) sulfate and pH on germination, growth, and nutrient and polyamine contents in Cedrela fissilis seedlings. The results showed that iron(II) sulfate and pH treatments decreased germination and fresh matter, and higher concentrations of iron(II) sulfate at pH 3 increased the content of Fe, Mn, Zn, Ca, and N in the roots. An increase in polyamine content in the roots may be an adaptive response to iron stress. The findings suggest that C. fissilis has the potential for ecological restoration in iron-contaminated areas.
