“…Zn is beneficial for growth, while Cd is a dangerous heavy metal that can inhibit plant growth only at low concentration. In previous studies, researchers have found that Cd stress can reduce the absorption of Zn by plants [ 59 ], while the appropriate addition of Zn can reduce the absorption of Cd by plants and improve the utilization of other elements [ 60 ], but studies have also found that Zn The inhibition of Cd absorption depends on the ratio of the two concentrations [ 61 ]. The ZIP gene family may play a crucial role in regulating the transport of Zn and Cd.…”

The ZIP protein (ZRT, the IRT-like protein) is an important metal transporter that transports Zn, Fe, and other divalent metal ions in plants. In this study, we identified 20 ZIP genes in lettuce (Lactuca sativa L.). We used bioinformatics methods and renamed them according to their E value in hmmsearch. We also analyzed their gene structure, chromosomal location, constructed a phylogenetic tree, conserved motifs, performed synonymous analysis and responses to abiotic stresses. The results show that these LsZIP genes have 3–11 exons and were distributed unequally on 8 of the 9 chromosomes in lettuce. Based on phylogenetic analyses, the LsZIP gene family can be divided into three subfamilies, and the LsZIP genes within the same subfamily shared similar gene structure. The LsZIP genes contain 12 Motifs, of which Motif1 to Motif8 are widely distributed in group Ⅰ. Furthermore, the LsZIP gene contains numerous hormones and anti-stress response elements. Real-time quantitative PCR demonstrated that most LsZIP genes is up-regulated under the elemental stress in this experiment, indicating that they are positively regulated. But different elemental stressors can induce the expression of LsZIP gene to varying degrees. The LsZIP genes also change in response to different elemental stresses. The present study serves as a basic foundation for future functional studies on the lettuce ZIP family.

“…Cd is an unessential element for plants. However, Cd can interact with other elements, such as zinc (Zn), copper (Cu), and manganese (Mn), and affect their uptake and translocation ( Lachman et al, 2015 ). Some studies have reported that Cd can affect plant development in various plant species by inhibiting the absorption of water and nutrients, resulting in various symptoms of injury in vivo or in vitro ( Li et al, 2008 ).…”

Cadmium (Cd) toxicity seriously affects the growth and development of plants, so studies on uptake, translocation, and accumulation of Cd in plants are crucial for phytoremediation. However, the molecular mechanism of the plant response to Cd stress remains poorly understood. The main objective of this study was to reveal differentially expressed genes (DEGs) under lower (BT2_5) and higher (BT43) Cd concentration treatments in creeping bentgrass. A total of 463,184 unigenes were obtained from creeping bentgrass leaves using RNA sequencing technology. Observation of leaf tissue morphology showed that the higher Cd concentration damages leaf tissues. Four key transcription factor (TF) families, WRKY, bZIP, ERF, and MYB, are associated with Cd stress in creeping bentgrass. Our findings revealed that these four TFs play crucial roles during the creeping bentgrass response to Cd stress. This study is mainly focused on the molecular characteristics of DEGs under Cd stress using transcriptomic analysis in creeping bentgrass. These results provide novel insight into the regulatory mechanisms of respond to Cd stress and enrich information for phytoremediation.

“…In addition to toxic metals, changes in the membranes of plant cells are mostly affected by water stress, changes in temperature and by frost. Toxicity of the metals (such as cadmium), can cause an accumulation in tissues, which consequently affects the metabolism of plants, particularly the photosynthetic apparatus (Lachman et al, 2015).…”

Heavy metals and other toxic elements in the environment, mainly located in soil and groundwater, have a significant effect on plant and its productivity that has a huge attention in recent years. Accumulation of heavy metals in soil cause toxicity to plants, and contaminate the food chain. The industrial areas, as well as developing countries have been contaminated with high concentration of heavy metals. Main sources of contamination are mining and other industrial processes, as well as military and or lanfills, sludge dumps or waste disposal sites. The heavy metals are very dangerous to environment and pose serious danger to public health by entering throught the food chain or into drinking water. Phytoextraction is one way how to remove the contaminants from soil by plants. Phytoextraction of heavy metals is a technology that has been studied for several years. It is more ecological and cheaper way how to clean our environment.Several plant species are known becauce they hyperaccumulate a high contents of metals from the soil. The accumulators are mainly herbaceous species, crops and nowadays angiosperm trees with a high growth such as poplars or willows. We have focused on the determination of some morphological (lenght and weight of roots and biomass) and physiological (contents of dry mass and number of lief stomata) characteristics and the determination of the bioaccumulation factor and the translocation factor of cadmium by spring barley (Hordeum vulgare L.). Imprints of leaves were evaluated using an optical microscope Axiostar Plus, Carl Zeiss, lens CP Achromat 40x/0.65, eyepiece PI 10x / 18, Canon Utilities Software Zoom Browser EX 4.6 and hardware Acer Travel Mate 4600, Canon Power Shot A95. The density of stomata was evaluated on an area of 1 mm 2 . Samples of the dried plants (leaves and roots) were mineralized by acid digestion using microwave digestion device MARS X -press 5. The end of determination to obtain the cadmium content was performed by atomic absorption spectrometer Varian 240 Z with GTA120 graphite furnace. The effect of contamination by cadmium to germination, length of leaves and number of stomata on abaxial side of leaf was confirmed. The contaminated soil by cadmium does not pose a risk of heavy metal entry into the feed and food chain by spring barley (Hordeum vulgare L.).
