“…A recent study also suggested that exogenous application of different growth regulating compounds (hormones, antioxidants, micro or macronutrients, and nanoparticles) significantly improve the plant growth by alleviating the damaging effects of abiotic stresses. These exogenously applied ameliorants positively regulates the synthesis and functional activities of osmo-protectants, enzymatic and non-enzymatic antioxidant related defensive compounds which leads to sustainable plant productivity [ 39 ]. Particularly, seed priming with calcium chloride (CaCl 2 ) or potassium nitrate (KNO 3 ) breaks the high temperature stress induced seed dormancy and promote the uniformed seed germination with increased plant density and biomass accumulation [ 40 ].…”

Early season carrot (Daucus carota) production is being practiced in Punjab, Pakistan to meet the market demand but high temperature hampers the seed germination and seedling establishment which cause marked yield reduction. Seed priming with potassium nitrate breaks the seed dormancy and improves the seed germination and seedling growth potential but effects vary among the species and ecological conditions. The mechanism of KNO3 priming in high temperature stress tolerance is poorly understood yet. Thus, present study aimed to evaluate high temperature stress tolerance potential of carrot seeds primed with potassium nitrate and impacts on growth, physiological, and antioxidant defense systems. Carrot seeds of a local cultivar (T-29) were primed with various concentration of KNO3 (T0: unprimed (negative control), T1: hydroprimed (positive control), T2: 50 mM, T3:100mM, T4: 150 mM, T5: 200 mM, T6: 250 mM and T7: 300 mM) for 12 h each in darkness at 20 ± 2℃. Seed priming with 50 mM of KNO3 significantly enhanced the seed germination (36%), seedling growth (28%) with maximum seedling vigor (55%) and also exhibited 16.75% more carrot root biomass under high temperature stress as compared to respective control. Moreover, enzymatic activities including peroxidase, catalase, superoxidase dismutase, total phenolic contents, total antioxidants contents and physiological responses of plants were also improved in response to seed priming under high temperature stress. By increasing the level of KNO3, seed germination, growth and root biomass were reduced. These findings suggest that seed priming with 50 mM of KNO3 can be an effective strategy to improve germination, growth and yield of carrot cultivar (T-29) under high temperature stress in early cropping. This study also proposes that KNO3 may induces the stress memory by heritable modulations in chromosomal structure and methylation and acetylation of histones that may upregulate the hormonal and antioxidant activities to enhance the stress tolerance in plants.

“…Metal(loid)s disrupt intracellular homeostasis, triggering oxidation in vital macromolecules like lipids, proteins, genetic material, and enzymes. This oxidative stress results from the overproduction of free radicals and impaired pro-oxidant and antioxidant systems in plant cells (Thakur et al 2022 ; Basit et al 2023 ). Oxidative-stress-mediated metal(loid) toxicity primarily affects various intracellular organelles and components, including cell membranes, mitochondria, chloroplasts, and some proteins involved in detoxification and metabolism (Kumar et al 2016 ; Hasan et al 2017 ).…”

“…Some nutritional metal(loid)s, including Cu, Zn, Ni, Fe, and Se, are vital in trace amounts (Karthika et al 2018 ; Kumar et al 2021 ) but become lethal when accumulated in excess amounts in plants (Karthika et al 2018 ; Kumar et al 2021 ). Conversely, non-essential toxic metal(loid)s like As, Cd, Pb, and Hg are harmful even in small amounts (Pokorska-Niewiada et al 2018 ; Paz et al 2019 ; Kumar et al 2021 ), causing reduction in growth, biomass, and yield, disruptions in water and nutrient balance, chlorosis, inhibition of the electron transport chain, denaturation of essential enzymes and proteins, generation of reactive oxygen species (ROS), lipid peroxidation, restricted movement of essential nutrients, and even plant death (Edelstein and Ben-Hur 2018 ; Kosakivska et al 2021 ; Raza et al 2022 ; Hassan et al 2022 ; Thakur et al 2022 ; Ghuge et al 2023 ; Basit et al 2023 ). Due to their toxic nature, certain non-essential metal(loid)s tend to replace beneficial elements in critical enzymes and pigments, disrupting their functionality (Erickson et al 2019 ; Kosakivska et al 2021 ; Thakur et al 2022 ; Ghuge et al 2023 ).…”

The escalating challenges posed by metal(loid) toxicity in agricultural ecosystems, exacerbated by rapid climate change and anthropogenic pressures, demand urgent attention. Soil contamination is a critical issue because it significantly impacts crop productivity. The widespread threat of metal(loid) toxicity can jeopardize global food security due to contaminated food supplies and pose environmental risks, contributing to soil and water pollution and thus impacting the whole ecosystem. In this context, plants have evolved complex mechanisms to combat metal(loid) stress. Amid the array of innovative approaches, omics, notably transcriptomics, proteomics, and metabolomics, have emerged as transformative tools, shedding light on the genes, proteins, and key metabolites involved in metal(loid) stress responses and tolerance mechanisms. These identified candidates hold promise for developing high-yielding crops with desirable agronomic traits. Computational biology tools like bioinformatics, biological databases, and analytical pipelines support these omics approaches by harnessing diverse information and facilitating the mapping of genotype-to-phenotype relationships under stress conditions. This review explores: (1) the multifaceted strategies that plants use to adapt to metal(loid) toxicity in their environment; (2) the latest findings in metal(loid)-mediated transcriptomics, proteomics, and metabolomics studies across various plant species; (3) the integration of omics data with artificial intelligence and high-throughput phenotyping; (4) the latest bioinformatics databases, tools and pipelines for single and/or multi-omics data integration; (5) the latest insights into stress adaptations and tolerance mechanisms for future outlooks; and (6) the capacity of omics advances for creating sustainable and resilient crop plants that can thrive in metal(loid)-contaminated environments.

“…Plants have their innate ability to prevent the generation of ROS during normal photosynthetic and respiratory metabolism through antioxidant defense systems. However, overly-produced ROS under saline conditions overwhelms the inherent antioxidant defense systems, resulting in oxidative stress in plants ( Basit et al., 2023 ). Salinity, therefore, creates challenges to sustainable agriculture and the production of sufficient food to meet global food requirements and ensure future food and nutritional security.…”

IntroductionThe ongoing global expansion of salt-affected land is a significant factor, limiting the growth and yield of crops, particularly rice (Oryza sativa L). This experiment explores the mitigation of salt-induced damage in rice (cv BRRI dhan100) following the application of plant growth-promoting rhizobacteria (PGPR).MethodsRice seedlings, at five- and six-weeks post-transplanting, were subjected to salt stress treatments using 50 and 100 mM NaCl at seven-day intervals. Bacterial cultures consisting of endophytic PGPR (Bacillus subtilis and B. aryabhattai) and an epiphytic PGPR (B. aryabhattai) were administered at three critical stages: transplantation of 42-day-old seedlings, vegetative stage at five weeks post-transplantation, and panicle initiation stage at seven weeks post-transplantation.ResultsSalt stress induced osmotic stress, ionic imbalances, and oxidative damage in rice plants, with consequent negative effects on growth, decrease in photosynthetic efficiency, and changes in hormonal regulation, along with increased methylglyoxal (MG) toxicity. PGPR treatment alleviated salinity effects by improving plant antioxidant defenses, restoring ionic equilibrium, enhancing water balance, increasing nutrient uptake, improving photosynthetic attributes, bolstering hormone synthesis, and enhancing MG detoxification.DiscussionThese findings highlight the potential of PGPR to bolster physiological and biochemical functionality in rice by serving as an effective buffer against salt stress–induced damage. B. subtilis showed the greatest benefits, while both the endophytic and epiphytic B. aryabhattai had commendable effects in mitigating salt stress–induced damage in rice plants.
