“…RNA-seq analysis show that TaZFP1 regulates photosynthesis, osmolyte metabolism, and ROS-homeostasisrelated genes involved in salt stress (Sun et al, 2019a). AtRZFP enhances salt tolerance by increasing ROS scavenging and maintaining Na + and K + homeostasis (Zang et al, 2016).…”

Abiotic stresses such as drought and salinity are major environmental factors that limit crop yields. Unraveling the molecular mechanisms underlying abiotic stress resistance is crucial for improving crop performance and increasing productivity under adverse environmental conditions. Zinc finger proteins, comprising one of the largest transcription factor families, are known for their finger-like structure and their ability to bind Zn 2+ . Zinc finger proteins are categorized into nine subfamilies based on their conserved Cys and His motifs, including the Cys2/His2-type (C2H2), C3H, C3HC4, C2HC5, C4HC3, C2HC, C4, C6, and C8 subfamilies. Over the past two decades, much progress has been made in understanding the roles of C2H2 zinc finger proteins in plant growth, development, and stress signal transduction. In this review, we focus on recent progress in elucidating the structures, functions, and classifications of plant C2H2 zinc finger proteins and their roles in abiotic stress responses.

“…Glutathione peroxidase and peroxidase family proteins expression indicates higher response to oxidative stress, glutathione peroxidase activity, metal ions binding & transportation activity [Alzahrani et al 2018; Martinez et al, 2018]. Interestingly, number of transcripts of zinc finger transcription factors and helicase-like transcription factor were expressed in HZFWGs showed their function in various transcription factor activity, sequence-specific DNA and metal ion binding and stress response [Bouain et al, 2014; Zang et al, 2016; Sarwat et al, 2018]. Accompanied number of transcripts of wheat are also expressed those are only involved in different STR.…”

Development of Zinc (Zn), Iron (Fe) and other minerals rich grains along with various stress tolerance and susceptible (STR) wheat genotype, will help to reduce globally spread malnutrition problem. Current study deals with transcriptome profiling of 4 high- and 3 low- Zn & Fe accumulating wheat genotypes (HZFWGs) and (LZFWGs). Functional characterization of expressed and high and low specific genes, accompanied by metabolic pathways analysis reveals, phenylpropanoid biosynthesis, and other associated pathways are mainly participating in plant stress defense mechanism in both genotypes. Chlorophyll synthesis, Zn & Fe binding, metal ion transport, and ATP-Synthase coupled transport mechanism are highly active in HZFWGs while in LZFWGs ribosomal formation, biomolecules binding activities and secondary metabolite biosynthesis. Transcripts accountable for minerals uptake and purine metabolism in HZFWGs are highly enriched. Identified transcripts may be used for marker-assisted selection and breeding to develop minerals rich crops.

“…This suggests these nutrients likely communicate with N-containing metabolites to play a role in cellular osmotic adjustment response and ROS detoxification to oxidative stress induced by heavy/toxic metals (e.g., Mn, Al, Zn) and/or salinity stress in these red maple trees. Furthermore, altered cellular K+/Na+ homeostasis can induce cellular desiccation (i.e., lower cell water content) and signal an osmotic stress response that triggers the regulation of water and nutrient balance, regulation of iWUE, and cellular osmotic adjustment [26,[46][47][48]. Interestingly, McDermot et al [3] found increased foliar Mg, very toxic levels of Mn, and lower chlorophyll and proline in red maple trees growing in low soil pH and low soil organic matter in Newark forests compared to Philadelphia forests.…”

Environmental conditions, such as temperature, carbon dioxide, and nutrient availability, are altered by urban conditions at regional scales with potential for impact on tree leaf structure. Our goal was to compare leaf morphological characteristics driven by physiological acclimation in red maple (Acer rubrum L.) trees in deciduous forests embedded in a small (Newark, DE) and a large (Philadelphia, PA) city. The study was conducted in six urban forests on eighteen mature red maple trees in a long-term urban forest network. We hypothesized that red maples in Philadelphia forests compared to Newark forests will have a thicker upper epidermal layer, spongy palisade and mesophyll layer, longer and wider stomates, and lower stomate density. Additionally, we hypothesized that red maples in Philadelphia forests compared to Newark forests will have lower leaf water content and specific leaf area, and greater leaf thickness, fresh leaf weight, dry leaf weight, and leaf dry matter content. Our results for stomate length and stomate width supported our predictions; red maple leaves had longer and wider stomates in Philadelphia forests than in Newark forests. The increased stomate size in red maple trees suggests potential altered gas exchange behavior and mutual abiotic stress mitigation responses in red maple to greater urbanization impacts in Philadelphia forests. This supports previous findings of possible physiological and biochemical acclimation of red maple trees to urban conditions. Furthermore, the findings from this study suggest red maple trees may be a good biomonitor of regional scale impacts in urban environments.Forests and trees have the potential to improve environment quality in urban areas through blockage, uptake, and immobilization of pollutants [12,13]. Plant leaves have the ability to trap, sequester, and compartmentalize pollutants [14,15]. Urban forest trees may also provide important benefits through pollution regulation of urban conditions. However, this is debatable due to biogenic volatile organic compound (BVOC) production by urban trees [16 ], and for some pollutants, like particulates, the aerodynamic effect of tree canopies can influence particulate residence time, recirculation, and concentration in urban environments [17,18]. Alternatively, urban air pollutants can affect tree growth and function; tropospheric ozone has been reported to induce visible injuries, de-regulate stomatal conductance, and reduce photosynthesis and leaf area [19,20]. These complex interactions with urban tree canopies and atmospheric pollutants may stress trees, leading to shorter lifespan even with enhanced growth rates [21]. Thus, the ability of urban trees to mitigate urban conditions and improve environment quality and sustainability of cities may be dampened by their response to altered urban environmental conditions [17,22,23].The morphological and anatomical traits in leaves can serve as a bioindicator of plant response to altered environmental conditions, specifically air [15,24] and soil [2,25,26] polluti...
