Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner order to fulfill food demands an ever-increasing global population. However, intensive agricultural practices, rampant use agrochemicals, environmental factors result soil fertility degradation, pollution, disruption biodiversity, pest resistance, decline crop yields. Thus, experts are shifting their focus eco-friendly safer methods fertilization ensure sustainability. Indeed, importance plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, usage biofertilizers being actively promoted means mitigating harmful effects agrochemicals. As bio-elicitors, PPs promote growth colonize or tissues when administered soil, seeds, surface used alternative avoid heavy In past few years, nanotechnology brought revolution due application various nanomaterials (NMs) nano-based fertilizers increase productivity.

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.

Plant-associated microbes include taxonomically diverse communities of bacteria, archaebacteria, fungi, and viruses, which establish integral ecological relationships with the host plant constitute phyto-microbiome. The phyto-microbiome not only contributes in normal growth development plants but also plays a vital role maintenance homeostasis during abiotic stress conditions. Owing to its immense metabolic potential, provides capability mitigate through various mechanisms like production antioxidants, hormones, bioactive compounds, detoxification harmful chemicals toxins, sequestration reactive oxygen species other free radicals. A deeper understanding structure functions complex mediated mitigation would enable utilization for alleviation crop stress-resistant crops. This review aims at exploring potential alleviate drought, heat, salinity heavy metal finding sustainable solutions enhance agricultural productivity. mechanistic insights into phytomicrobiome imparting tolerance have been summarized, that be helpful novel bioinoculants. high-throughput modern approaches involving candidate gene identification target modification such as genomics, metagenomics, transcriptomics, metabolomics, based genetic engineering discussed wake ever-increasing demand climate resilient plants.

Abstract Mercury (Hg), arsenic (As), cadmium (Cd), lead (Pb) and other toxic heavy metals (HM) pose significant risks to the environment, negatively impacting morpho-physiological biological traits of plants. At present, elements constitute a proportion food chain, exerting an impact on human health due their mobility biomagnification. The metal exclusion technique stands out for its robust performance, even when dealing with extremely low concentrations. Its eco-friendly nature cost-effectiveness further enhance value. Due exponential growth pattern bacteria, these exhibit high persistence are recommended processes. Moreover, vacuoles like vesicles present in mycorrhizal fungi can hold levels HM. Microbe-assisted phytoremediation primarily occurs through two mechanisms: direct provision essential nutrients phytohormones, such as plant regulators, siderophores, enzymes, mineral; or indirectly by modulating detoxification process. This indirect mechanism involves microbes aiding accumulation sequestration plants secretion specific extracellular substances organic acids, biosurfactants, chelators. bioavailability translocation rhizosphere also altered via various mechanisms acidification, precipitation, complexation redox reactions. understanding molecular physiological processes underpinning functions arbuscular (AMF) reducing HM toxicity, improving performance procuring under HM-toxicity has significantly improved recent years.

Wild tomato species exhibit natural insect resistance, yet the specific secondary metabolites and underlying mechanisms governing resistance remain unclear. Moreover, defense expression dynamically adapts to herbivory, causing significant metabolic changes species-specific metabolite accumulation. The present study aims identify resistance-related in wild accessions that influence mechanism against whitefly (Bemisia tabaci Asia II 7) leafminer (Phthorimaea absoluta). In this study, LC-HRMS-based non-targeted metabolomics of resistant (Solanum cheesmaniae Solanum galapagense) susceptible cultivated lycopersicum) following 6- 12-h post-infestation (hpi) by B. 7 P. absoluta revealed distinct sets constitutive (RRC) induced (RRI) metabolites. key were those involved fatty acid associated biosynthesis pathways (e.g., triacontane, di-heptanoic acid, dodecanoic undecanoic N-hexadecanoic pentacosane, monogalactosyldiacylglycerols, sphinganine, 12-hydroxyjasmonic acid), which are recognized for their direct or indirect role mediating plant insects. Additionally, differential accumulation was evident through partial least squares-discriminant analysis (PLS-DA), highlighting differences profiles between at 6 12 hpi absoluta. Volcano plot a higher number significantly upregulated herbivory. responded uniquely absoluta, responses two feeding guilds. This uncovered biochemical accessions, elucidated dual herbivory on metabolome, offered well-characterized parent materials candidate breeding insect-resistant varieties.
