“…Furthermore, the overproduction of ROS in wheat seedlings upon Cd exposure, marked by an increase in the hydrogen peroxide (H 2 O 2 ) content and malondialdehyde (MDA) level, was linked to genotoxicity [64]. Being sessile, plants try to elude its harmful effects by adopting various defense mechanisms, which include antioxidant activation and other mechanisms of metal homeostasis [65]. In response, plants have developed enzymatic and non-enzymatic antioxidant mechanisms.…”

Cadmium (Cd) is one of the most toxic metals in the environment, and has noxious effects on plant growth and production. Cd-accumulating plants showed reduced growth and productivity. Therefore, remediation of this non-essential and toxic pollutant is a prerequisite. Plant-based phytoremediation methodology is considered as one a secure, environmentally friendly, and cost-effective approach for toxic metal remediation. Phytoremediating plants transport and accumulate Cd inside their roots, shoots, leaves, and vacuoles. Phytoremediation of Cd-contaminated sites through hyperaccumulator plants proves a ground-breaking and profitable choice to combat the contaminants. Moreover, the efficiency of Cd phytoremediation and Cd bioavailability can be improved by using plant growth-promoting bacteria (PGPB). Emerging modern molecular technologies have augmented our insight into the metabolic processes involved in Cd tolerance in regular cultivated crops and hyperaccumulator plants. Plants’ development via genetic engineering tools, like enhanced metal uptake, metal transport, Cd accumulation, and the overall Cd tolerance, unlocks new directions for phytoremediation. In this review, we outline the physiological, biochemical, and molecular mechanisms involved in Cd phytoremediation. Further, a focus on the potential of omics and genetic engineering strategies has been documented for the efficient remediation of a Cd-contaminated environment.

“…These oxygen species directly attack on membrane lipids and proteins by amino acid modifications and degradation of peptide chains. ROS affect membrane integrity which is evident from malondialdehyde (MDA) production due to lipid peroxidation in rice (41) and many other plants. Excessive levels of Cd (100 mg Cd/kg of soil) induces chlorosis and root necrosis in rice followed by acute oxidative stress due to ROS generation (42) leading to significant decrease in root-shoot length (41).…”

Application of nanoparticles to address various environmental issues; especially heavy metal contaminated soil restoration is of global interest. Indiscriminate usage of phosphate fertilizer and other anthropogenic activities contribute to Cd contamination of soil, resulting in degradation of soil quality and low crop yield. By the virtue of unique physiochemical characteristics, nanoparticles (NPs) are effective enough for heavy metal stress mitigation. This review has focused on Cd uptake, accumulation and toxicity in plants followed by the successful application of different metallic and non metallic NPs for soil Cd decontamination. Positive impact of NPs as plant growth elicitor under Cd stress has been explored here. Various ways of NP application (soil, foliar, hydroponics), uptake, mode of action and effective treatment concentration have been highlighted. We have collected handful information regarding the use of NPs as nanofertilizer and nanopesticides. The negative effects of NPs have not been considered here. More in depth study to be conducted for better illumination on plant - NPs interaction, mobilization mechanism and biological activities. Though this review summarizes few facts among various aspect of NP but can be counted as a supportive documentation for the better use of NPs in environmental protection in future.

“…The number of flowers and their traits can also be influenced by post‐ontogenic events, such as Cd‐induced over‐ or undernutrition (Hédiji et al, 2015) and hyper‐ or hypoproduction of hormones (Souza et al, 2018), triggering from negative to positive outcomes (Carvalho, Castro, & Azevedo, 2020). For instance, Cd reduced the quantity of total and effective tillers in rice ( Oryza sativa ; Barman, Majumdar, Arzoo, & Kundu, 2020), and the number of flowers in tomato ( Solanum lycopersicum ; Hédiji et al, 2015). By contrast, the quantity of flowers in sunflower ( Helianthus annuus ) was accompanied by enhanced Cd accumulation (Hao, Zhou, Li, & Jiang, 2012).…”

“…By contrast, grain yield was reduced in rice plants under Cd exposure (Barman et al, 2020). According to the authors, Cd interference on grain filling (as measured by increased percentage of hollow grains) accompanied by decreased number of grains, was responsible for productivity losses.…”

“…Although the ‘life history’ of plants under Cd‐induced stress is scarcely studied, such information is relevant to understand past, present and future ecological and evolutionary events. In both rice and maize plants, the flowering time and, consequently, the grain maturation time was delayed by Cd exposure (Ahmad et al, 2012; Barman et al, 2020), suggesting a prolonged period to complete the plant biological cycle. These results are consistent with evidences from diverse sources that indicate a general selection pressure for slow syndrome strategies in stressful environments (Sartori et al, 2019).…”

Studies involving the effects of long‐term exposure of plants to cadmium (Cd) are not usual, hence, data about Cd‐induced impacts on plant reproductive organs are scarce. The lack of robust information about this matter is surprising and also worrying because it is not yet clear whether (and how strong) Cd influences yield, and quality of fruits and seeds. Such information is necessary to guide strategies to manage crops and to avoid negative impacts on the environment and human health. This review gathers information about the effects of long exposure of flowers, fruits and seeds to Cd. A critical analysis of the data related to this matter, which have been published in the last 30 years, was performed. Ecological and evolutionary aspects were also discussed, and new insights were provided. The information about Cd‐induced effects on fruit and seed quality is relevant to support not only further scientific studies, but also environmental, economic and health policies in times of increasing heavy metal pollution in agricultural areas.
