“…Here, 8cDNA libraries identified 4484 novel genes from which 6798 were grouped to Cd-related DEGs among two cultivars, first Fenghua 1 (low-Cd) and second Silihong (high-Cd). A total of 183 DEGs were to be found linked to ion transport-related proteins (ZIPs, MTPs, Nramps, and YSLs), among them 9 genes related to the cell wall and 9 genes specifically related to metal transport from which 4 were linked to endomembrane-tonoplast transported genes (MTP4, ABCC4, ABCC15, and ZIP11), four Cd efflux genes (YSL7, FRD3, PDR12, and ZIP1), and one Cd influx gene (IRT1); higher expression in Fenghua 1 might be related to the difference in Cd transport and accumulation among the two cultivars [260]. Creeping bentgrass transcriptional analysis showed four transcription factors (bZIP, WRKY, MYB, and ERF) linked with cd stress [261].…”

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.

“…Cd is a non-essential element for plants, generally transported into root cells accompanied by other cations, such as Zn, Ca and Fe. Some proteins belonging to the ZIP family, NRAMP, CDF and CPx-ATPase are involved in Cd transport from soil (Yu et al, 2018). Most up-regulated genes in female roots induced by Cd stress were involved in transport processes, such as YELLOW STRIPE LIKE 7, Zinc transporter 2, Zinc transporter 11 and cation exchanger 3 (Figs 6-7).…”

This study clarifies the mechanisms of Cd uptake, translocation and detoxification in Populus cathayana Rehder females and males, and reveals a novel strategy for dioecious plants to cope with Cd contamination. Females exhibited a high degree of Cd uptake and root-to-shoot translocation, while males showed extensive Cd accumulation in roots, elevated antioxidative capacity, and effective cellular and bark Cd sequestration. Our study also found that Cd is largely located in epidermal and cortical tissues of male roots and leaves, while in females, more Cd was present in vascular tissues of roots and leaves, as well as in leaf mesophyll. In addition, the distributions of sulphur (S) and phosphorus (P) were very similar as that of Cd in males, but the associations were weak in females. Scanning electron microscopy and energy spectroscopy analysess suggested that the amounts of tissue Cd were positively correlated with P and S amounts in males, but not in females (a weak correlation between S and Cd). Transcriptional data suggested that Cd stress promoted the upregulation of genes related to Cd uptake and translocation in females, and that of genes related to cell wall biosynthesis, metal tolerance and secondary metabolism in males. Our results indicated that coordinated physiological, microstructural and transcriptional responses to Cd stress endowed superior Cd tolerance in males compared with females, and provided new insights into mechanisms underlying sexually differential responses to Cd stress.

“…, pakchoi(Zhou et al 2016) and peanut (Arachis hypogaea L.)(Yu et al 2018), the higher expression of adenosine triphosphate-binding cassette transporters in low-Cd cultivars was reported to be responsible for the vacuolar sequestration of Cd-phytochelatin or Cd-glutathione complex, and consequently, reducing root-to-shoot Cd translocation. Thus,different strategies of Cd detoxi cation and translocation depending on vacuole sequestration should be deployed between low-Cd and high-Cd eggplant cultivars.…”

Excessive accumulation of cadmium (Cd) in vegetables poses a serious threat to human health; therefore, it is urgent to screen and cultivate vegetable cultivars with low Cd accumulation in the edible parts. Eggplant has a high tendency for Cd accumulation, but research on its low Cd accumulation cultivars is still rare. In this study, to screen low-Cd cultivars, 30 eggplant cultivars were screened using soils containing 0.22 mg/kg, 2.9 mg/kg (low-Cd), and 4.7 mg/kg of Cd (high-Cd). MYCQ and ZGQ were con rmed as low-Cd cultivars, BXGZ and WCCQ were con rmed as high-Cd cultivars, and a 2.52-3.88 fold difference in Cd concentration was observed in their fruits. The subcellular distribution revealed that the root cell wall and vacuole Cd concentrations of a typical low-Cd cultivar (MYCQ) were signi cantly higher than those of a typical high-Cd cultivar (BXGZ); however, the Cd concentrations in the cell wall and vacuole in fruits, leaves, and stems were signi cantly lower in MYCQ than in BXGZ. These results indicated that the low-Cd cultivars of eggplant could lessen Cd toxicity through the elevated Cd retention and sequestration levels of root cell walls and vacuoles, thus reducing Cd transport from roots to aboveground tissues, leading to low Cd accumulation. The ndings of this study can provide a physiological and biochemical foundation for the screening and breeding of low-Cd cultivars of fruit vegetables and demonstrates that the application of low-Cd cultivars is necessary for food safety in humans.
