“…Our results also illustrated that the application of N, P, and K decreased oxidative stress indicators while on the other hand increasing the activities of enzymatic and non-enzymatic antioxidants such as SOD, POD, CAT, soluble protein, proline, and chloroplastic pigments. Our findings are supported by many earlier studies, that observed increased MDA, EL, and H 2 O 2 production under cold stress (Jan et al, 2018;Fan et al, 2020;Liu et al, 2020;Su et al, 2021;Ma et al, 2022), N deprivation (Tantray et al, 2020), P deprivation (Noor et al, 2021), and K deprivation (Seleiman et al, 2021). Higher accumulation of MDA, EL, and H 2 O 2 under N deprivation as compared with P and K was corroborated by earlier studies (Tewari et al, 2007;Hussain et al, 2016).…”

“…Results with increased enzymatic activities under stress conditions in response to N, P, and K are recently reported by Ma et al (2022). Corresponding results with N fertilization (Chang et al, 2016;Ahanger et al, 2019), P fertilization (Noor et al, 2021), and K fertilization (Seleiman et al, 2021) have been previously reported.…”

Overseeded perennial ryegrass (Lolium perenne L.) turf on dormant bermudagrass (Cynodon dactylon Pers. L) in transitional climatic zones (TCZ) experience a severe reduction in its growth due to cold stress. Primary plant nutrients play an important role in the cold stress tolerance of plants. To better understand the cold stress tolerance of overseeded perennial ryegrass under TCZ, a three-factor and five-level central composite rotatable design (CCRD) with a regression model was used to study the interactive effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on lipid peroxidation, electrolyte leakage, reactive oxygen species (ROS) production, and their detoxification by the photosynthetic pigments, enzymatic and non-enzymatic antioxidants. The study demonstrated substantial effects of N, P, and K fertilization on ROS production and their detoxification through enzymatic and non-enzymatic pathways in overseeded perennial ryegrass under cold stress. Our results demonstrated that the cold stress significantly enhanced malondialdehyde, electrolyte leakage, and hydrogen peroxide contents, while simultaneously decreasing ROS-scavenging enzymes, antioxidants, and photosynthetic pigments in overseeded perennial ryegrass. However, N, P, and K application mitigated cold stress-provoked adversities by enhancing soluble protein, superoxide dismutase, peroxide dismutase, catalase, and proline contents as compared to the control conditions. Moreover, N, P, and, K application enhanced chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids in overseeded perennial ryegrass under cold stress as compared to the control treatments. Collectively, this 2−years study indicated that N, P, and K fertilization mitigated cold stress by activating enzymatic and non-enzymatic antioxidants defense systems, thereby concluding that efficient nutrient management is the key to enhanced cold stress tolerance of overseeded perennial ryegrass in a transitional climate. These findings revealed that turfgrass management will not only rely on breeding new varieties but also on the development of nutrient management strategies for coping cold stress.

“…The HM ions sequestered inside the vacuoles may move into the stele and join the xylem stream via the root symplasm, subsequently translocated to the shoots via xylem vessels ). Noor et al (2022a) and redistribution among aerial parts (Thakur et al, 2016). They are transported and distributed in leaves via apoplast or symplast, where the ions are confined in extracellular compartments (cell walls) or plant vacuoles, thereby stopping the buildup of free HM ions in the cytosol (Yan et al, 2020).…”

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.

“…Further, P plays an important role in regulating root system responses to drought stress (Jin et al, 2015;Attarzadeh et al, 2020), because P application prevents crop plants from oxidative stress and improve chloroplast structure, while excessive P application trigger ROS toxicity (Shibli et al, 2006;Noor et al, 2021). Combined with N and potassium (K), P application promotes the secondary root growth, proliferation of growing root tips, and root hair differentiation; subsequently root surface area increased that supports in active nutrient-water uptake (Gahoonia et al, 1999).…”

The 21st century presents many challenges to mankind, including climate change, fast growing human population, and serious concerns over food security. Wheat is a leading cereal crop that largely fulfills the global food needs. Low temperature stress accompanied by nutrient-starved soils is badly disrupting the source–sink relationship of wheat, thus causing an acute decline in final yield and deteriorating the grain quality. This review paper aimed to understand how low temperature stress affects wheat source–sink organs (i.e., leaves, roots, and spikes) and how phosphorus application reliefs in alleviating its harmful consequences. Also, we discussed mitigation strategies to enhance wheat capacity to adapt to varying temperature extremes and made rational recommendations based on modern agronomic and breeding approaches. Therefore, this study is likely to establish a solid foundation for improving the tolerance to low temperature stress and to improve its phosphorus utilization efficiency in wheat.
