Due to anthropogenic activities, environmental pollution of heavy metals/metalloids (HMs) has increased and received growing attention in recent decades. Plants growing in HM‐contaminated soils have slower growth and development, resulting in lower agricultural yield. Exposure to HMs leads to the generation of free radicals (oxidative stress), which alters plant morpho‐physiological and biochemical pathways at the cellular and tissue levels. Plants have evolved complex defense mechanisms to avoid or tolerate the toxic effects of HMs, including HMs absorption and accumulation in cell organelles, immobilization by forming complexes with organic chelates, extraction via numerous transporters, ion channels, signaling cascades, and transcription elements, among others. Nonetheless, these internal defensive mechanisms are insufficient to overcome HMs toxicity. Therefore, unveiling HMs adaptation and tolerance mechanisms is necessary for sustainable agriculture. Recent breakthroughs in cutting‐edge approaches such as phytohormone and gasotransmitters application, nanotechnology, omics, and genetic engineering tools have identified molecular regulators linked to HMs tolerance, which may be applied to generate HMs‐tolerant future plants. This review summarizes numerous systems that plants have adapted to resist HMs toxicity, such as physiological, biochemical, and molecular responses. Diverse adaptation strategies have also been comprehensively presented to advance plant resilience to HMs toxicity that could enable sustainable agricultural production.

Plant hormones play pivotal roles in stress responses by modulating growth, development, stomatal movement, and the expression of stress-related genes, thereby aiding plants in adapting to and managing various environmental challenges. Each hormone exhibits distinct functions and regulatory mechanisms in stress response, with potential complex interactions among them. Brassinosteroids (BRs) represent a novel hormone that influences the expression of its target genes through a series of phosphorylated cascade reactions involving various transcription factors. This signaling pathway regulates diverse growth and development processes in plants. Additionally, BRs interact with other hormones to modulate physiological development. This review examines BRs biosynthesis and metabolism, elucidates the interactions between BRs and abscisic acid (ABA), jasmonic acid (JA), and gibberellins (GA), and explores their roles in regulating responses to drought, salt, cold, and heat. The review underscores the importance of BRs and other hormonal crosstalk in managing nutrient stress, which is vital for understanding plant growth regulation, enhancing crop stress resistance, advancing biotechnology applications, and furthering plant science research. Future research directions and the potential of BRs production and application to improve plant stress resilience are also discussed in the context of current findings.
