Summary: In this study, the impact of AgNPs stabilized with different coatings on photosynthesis of tobacco plants and AgNP stability in exposure medium was investigated. Results showed that AgNP-citrate induced the least effects on chlorophyll a fluorescence parameters and pigment content due to fast agglomeration, while AgNP-PVP and AgNP-CTAB had more severe effects related to their stability, Ag accumulation, and surface charge. In conclusion, the intrinsic properties of AgNP coatings affect their stability and bioavailability, indirectly impacting photosynthetic apparatus.

Summary: Hydroponic experiments were conducted to investigate the effects of prolonged sulfate limitation and Cd exposure on Arabidopsis thaliana and Nicotiana tabacum. Both species showed adverse effects on morphology, photosynthetic and biochemical parameters, and nutritional status under low sulfate treatments and Cd stress. The responses to low sulfate supply, Cd exposure, or a combination of both factors were species-specific, and Cd exposure had opposing effects on the levels of certain elements in the roots.

Summary: This research identified several tobacco introductions with low alkaloid phenotypes through phenotyping and genotyping analysis. Some introductions achieved lower alkaloid accumulation by deleting specific genes, while others achieved low alkaloid phenotypes through the deletion of another gene. In addition, a new genomic region that may affect alkaloid accumulation was discovered through quantitative trait locus mapping.

Summary: Leaf senescence in tobacco is regulated by the BAG family of proteins, with NtBAG5c and NtBAG6a-b being upregulated in senescent leaves. NtBAG5c interacts with heat-shock protein 70 (HSP70) and sHSP20, and its silencing reduces lignin content and affects superoxide dismutase (SOD) activity and hydrogen peroxide (H2O2) accumulation. Silencing NtBAG5c also downregulates the expression of senescence-related genes. This study provides the first identification and characterization of tobacco BAG protein candidate genes.

Summary: Leaf aging is a crucial process during herbaceous plant senescence, influenced by internal and external factors, with chlorophyll catabolism being a key metabolism pathway resulting in leaf yellowing. Proteomics techniques, such as iTRAQ-PRM, can help identify proteins related to photosynthesis showing differential expression during senescence in tobacco plants. This study provides valuable insights into the regulation of tobacco leaf senescence at the proteomics level.

Summary: The study found that adding tobacco biochar in karst regions can increase the organic matter and fertility element contents in soil, although it may lead to an increase in soil CO2 emissions. This increase in CO2 emissions is compensated by the higher tobacco productivity and reduced sulfur content. Additionally, tobacco biochar amendments also increase carbon storage in soil.

Summary: Cadmium is a major heavy metal pollutant in the environment that severely limits crop growth. Glutathione plays a crucial role in plant cadmium tolerance by scavenging reactive oxygen species and biosynthesizing phytochelatins. This study found that cadmium stress affects maize metabolism differently in leaves and roots, and exogenous GSH can alleviate the toxic effects of cadmium stress by changing antioxidant-related metabolites.

Summary: A gene called HvVPE3 has been identified as a regulator of cadmium uptake and tolerance in barley. Silencing HvVPE3 can reduce cadmium levels and improve tolerance to cadmium stress, while overexpressing HvVPE3 leads to increased cadmium levels and hypersensitivity to cadmium stress. These findings offer potential for breeding barley varieties with low cadmium accumulation and high tolerance to cadmium.

Summary: Cadmium (Cd) is a harmful heavy metal contaminant, and long non-coding RNAs (lncRNAs) play significant roles in plant response to Cd stress. Transcriptome analysis of Cd-tolerant and Cd-sensitive barley genotypes revealed novel lncRNAs and differentially expressed lncRNAs between the two genotypes. Prediction and experimental analysis showed that some lncRNAs may act as target mimics of miRNAs in barley. Functional analysis of a key lncRNA demonstrated its important role in plant Cd tolerance.

Summary: Aluminum toxicity is a major constraint to crop production in acidic soils. This study investigated the changes in miRNA expression in the roots of two olive genotypes with contrasting aluminum tolerance. A total of 352 miRNAs were discovered, and 11 miRNAs showed significantly different expression patterns between the tolerant and sensitive genotypes under aluminum stress. In silico prediction identified potential target genes involved in transcriptional regulation, hormone signaling, transportation, and metabolism. These findings provide new insights into the regulatory roles of miRNAs in enhancing aluminum tolerance in olives.
