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: In this study, a comprehensive identification and analysis of GSTs in tea plant were conducted, and their important roles in plant growth, development, and stress responses were revealed. The study found that CsGSTs were unevenly distributed across the tea plant genome and tandem duplication was the main driving force for their expansion. Furthermore, CsGSTs were found to respond to multiple stresses and exhibit different expression patterns in different tissues. CsGSTU19, localized in the nucleus and cell membrane, was proven to be involved in tea plant defense against temperature stresses and Co. camelliae infection.

Summary: Non-essential toxic heavy metals like cadmium (Cd2+) have adverse effects on the growth and development of plants and can potentially harm human health. This study focused on the role of a peroxidase gene family member, PgGPx, in rice under Cd2+ stress. The overexpression of PgGPx enhanced Cd2+ tolerance in transgenic rice plants and improved oxidative stress response by increasing the activity of antioxidant enzymes. These findings provide insights for developing strategies to engineer Cd2+ stress tolerance in economically important crop plants.

Summary: This study investigated the role of Glutathione S-transferases (GSTs) in cold acclimation and cold stress-response mechanisms in the invasive snail P. canaliculata. A total of 30 PcGSTs were classified into seven classes and their expression patterns in different tissues were examined. RNA-seq analysis and qRT-PCR experiments revealed significant changes in expression levels of certain PcGST genes during cold acclimation, providing insights into the mechanisms underlying cold stress responses.

Summary: Contamination of paddy soils with arsenic can have toxic effects on rice plants and increase arsenic accumulation in grains. The uptake and detoxification of different arsenic species in rice is not fully understood. This study investigated the toxic effects of arsenite and arsenate on rice plants and the role of glutathione S-transferase in detoxifying arsenic. The results showed that arsenite was more detrimental to plant growth and lipid peroxidation than arsenate. Overexpression of glutathione S-transferase led to improved plant growth and lower lipid peroxidation under acute arsenite stress. Overall, arsenite was found to be more toxic to plants than arsenate and glutathione S-transferase has differential effects on plant reactions and tolerance to different arsenic species.

Summary: This study reveals the critical role of a JA-responsive glutathione S-transferase gene (SlGSTU24) in alleviating cold stress in tomato. SlGSTU24 is expressed in all tissues and is responsive to both JA and cold stress. Upregulation of SlGSTU24 attenuates cold-induced oxidative stress, while its expression is dependent on the crucial regulator of JA signaling pathway, SlMYC2. These findings uncover a crucial module MYC2-SlGSTU24 that maintains ROS homeostasis in tomato under cold conditions.

Summary: In this study, a total of 57 PcGST genes involved in anthocyanin accumulation in pear peels were identified through genomic analysis. Glutamic acid was found to significantly improve anthocyanin accumulation, with PcGST57 being the most significantly induced gene. Further experiments showed that overexpression of PcGST57 increased anthocyanin accumulation, while silencing of PcGST57 reduced anthocyanin content. These findings provide candidate genes for red pear breeding.

Summary: Cadmium (Cd) is a highly toxic metal that poses serious threats to both plant growth and human health. Hence, it is crucial to explore simple, practical, and eco-friendly methods to mitigate its toxicity. Previous research has mainly focused on the physiological and biochemical aspects of zinc sulfate application for enhancing plant tolerance to Cd, with insufficient investigation into the underlying molecular mechanisms. In this study, high and low concentrations of zinc sulfate were sprayed on seashore paspalum plants under Cd stress, and transcriptome sequencing and physiological indicators were employed to elucidate the mechanisms of Cd tolerance.
