Arsenic (As), an environmental pollutant, imposes toxic impacts on plant health. In recent years, researchers have focused comprehending the As-induced intrusion in growth and metabolic components. However, interactions between phosphorus (P) silicon (Si) remain elusive, specifically rice (Oryza sativa) cultivars. Therefore, present study investigated effects of P Si defense mechanisms, nutrients accumulation, carbohydrate metabolism, gibberellic acid (GA3) synthesis, responses Indica cultivars (landrace improved) under As stress. With this focus, our potentially indicated that stress (150 µM) negatively impacted underlying physiological traits, with more pronounced improved cultivar compared to landrace. (30 mg kg−1 soil) and/ or (1 mM) treatments prominently reduced oxidative mechanisms GA synthesis. Modulation enzymatic system increased both but landrace, including superoxide dismutase (+36.47%, +24.43%), ascorbate peroxidase (+95.11%, +78.26%), along non-enzymatic antioxidants such as (+29.43%, +21.48%), glutathione (+75.45%, +62.34%) concentrations, respectively. Notably, concentration (+23.78%, +16.48%) was substantially by cumulative application conspicuous Further, employing biosynthesis inhibitor, paclobutrazol (PBZ; 10 µM), substantiated input GA-mediated tolerance, wherein, PBZ reversed endogenous metabolism. summation, landrace outperformed leading tolerance. This implies could be used for future breeding programs permitting in-depth considerations Si-mediated GA3 synthesis conditions.

Abstract The primary factors that restrict agricultural productivity and jeopardize human food safety are heavy metals (HMs), including arsenic, cadmium, lead, aluminum, which adversely impact crop yields quality. Plants, in their adaptability, proactively engage a multitude of intricate processes to counteract the impacts HM toxicity. These orchestrate profound transformations at biomolecular levels, showing plant’s ability adapt thrive adversity. In past few decades, stress tolerance crops has been successfully addressed through combination traditional breeding techniques, cutting-edge genetic engineering methods, strategic implementation marker-dependent approaches. Given remarkable progress achieved this domain, it become imperative adopt integrated methods mitigate potential risks arising from environmental contamination on yields, is crucial as we endeavor forge ahead with establishment enduring systems. manner, nanotechnology emerged viable field sciences. applications extensive, encompassing regulation stressors like toxic metals, improving efficiency nutrient consumption alleviating climate change effects. Integrating nanomaterials agrochemicals mitigated drawbacks associated agrochemicals, challenges organic solvent pollution, susceptibility photolysis, restricted bioavailability. Numerous studies clearly show immense nanofertilizers tackling acute crisis toxicity production. This review seeks delve into using NPs effectively enhance resilience, thereby fostering an environmentally friendly economically approach toward sustainable advancement foreseeable future.

Assessing groundwater quality is essential for ensuring the sustainability of agriculture and ecosystems. This study evaluates contamination by heavy metals (HMs) using GIS approaches, multivariate statistical analysis (MSA), pollution indices (heavy metal index (HPI), (MI), degree (Cd), ecological risk (ERI), (PI)), human health assessment (HHRA). The results revealed significant variations in concentrations across area, with highest found southern southeastern parts, characterized intense agricultural activities uncontrolled landfills. Statistical analyses indicated both natural anthropogenic sources contamination. Pollution showed medium to high water levels, HPI values ranging from 20.23 128.60, MI 3.34 12.17, Cd 2.90 11.73, indicating varying degrees ERI suggested a low all samples. However, assessments highlighted non-carcinogenic carcinogenic risks, particularly children, TCR some like Ni Cr exceeding safe limits, potential hazards. findings provide valuable framework policymakers develop targeted strategies mitigating sustainable management.
