Summary: This study investigated the toxicological responses of D. lutheri to single and combined exposure of arsenic and other trace metals. The results showed that combined exposure significantly reduced cell number and chlorophyll a content, and increased the de-epoxidation ratio. Arsenic had a higher bio-concentration factor when mixed with other trace metals. This highlights the potential risks and bio-magnification effects of multiple contaminants and toxic trace metals in polluted areas.

Summary: The band degeneracy and thermoelectric performance of p-type skutterudites based on (Fe, Co)Sb3 can be effectively modified by adjusting the Co/Fe ratio. The optimal Co/Fe ratio was found to be 1.3:2.7, and the introduction of additional Sb compensated for Sb volatilization and improved the electrical transport performance. The sample Mm0.8Fe2.7Co1.3Sb12.60 achieved a peak figure of merit ZTmax of 1.06, which is one of the highest reported for (Fe, Co)Sb3-based p-type skutterudites.

Summary: The performance of stormwater best management practices (BMPs) in nutrient treatment varies greatly. To improve nutrient management with BMPs, it is necessary to understand the factors that influence stormwater BMP treatment processes. A meta-analysis of vegetated BMPs in the International Stormwater BMP Database was conducted to compare influent and effluent nitrogen and phosphorus concentrations and quantify the effect of BMPs on nutrient management across different climates. The study found that BMPs leach DIP and TP, increase the fraction of dissolved inorganic P (DIP:TP), and decrease dissolved N:P ratios.

Summary: This study investigated the allocation to growth, reproduction, and defence in maritime pine under different resource availability and simulated herbivory treatments. The results showed that fertilization increased tree growth and seed quantity but not seed quality. Needle clipping and methyl-jasmonate treatment increased needle resin and phenol concentrations. Overall, there were complex interactions among the life-history dimensions, suggesting that pairwise approaches are insufficient to unravel these complexities.

Summary: The xanthophyll cycle plays a significant role in protecting plants from membrane peroxidation induced by intense light exposure. This study identified 240 differentially expressed genes associated with respiratory chain, lipid metabolism, antioxidant activity, and flavonoid metabolism. The overexpression of the CmBCH1 gene resulted in the upregulation of genes involved in scavenging reactive oxygen species and encoding antioxidants, leading to the accumulation of xanthophyll, zeaxanthin, chlorophylls, and anthocyanins. The study highlighted the potential of BCH1 in regulating the xanthophyll cycle and enhancing tolerance to intense light stress in transgenic plants.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: This study identified and characterized 163 C2H2-type zinc finger proteins in non-heading Chinese cabbage. Two of these proteins, BcZAT12 and BcZAT10, were found to be closely related to cold tolerance and acted as transcriptional repressors in regulating cold resistance. Furthermore, BcZAT12 was shown to directly bind to the promoter of BcCBF1 and inhibit its activity. Additionally, interactions between BcZAT12 and other proteins such as BcABF2/4 were observed. These findings provide insights into the functional roles and regulatory mechanisms of C2H2-ZFPs in non-heading Chinese cabbage under cold stress.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
