“…High and low Cd accumulation cultivars have been identified in many crops, such as rape (Niu, 2012; Wu et al, 2015), pakchoi (Zhou et al, 2016), watercress (Wang et al, 2015), and Chinese leaf mustard (Dai et al, 2012). Differences in Cd absorption and accumulation among different turnip cultivars or genotypes also have been indicated in studies around the world (Bingham et al, 1975; Molahoseini and Feizi, 2012; Parveen et al, 2013).…”

“…Cruciferous plants are generally considered to represent the largest proportion of HM hyperaccumulators (He et al, 2009), and the earliest identified and most reported Cd hyperaccumulators are members of the Brassicaceae family (Zhao et al, 2002). In recent years, many studies of Cd absorption and accumulation have been performed for common cruciferous crops, such as rape (Carrier et al, 2003; Wang et al, 2009), Chinese cabbage (Aziz et al, 2015; Wu et al, 2015), pakchoi (Chen et al, 2010; Zhou et al, 2016), broccoli (Pedrero et al, 2008), and radish (Lagerwer, 1971; Vitoria et al, 2003; Lin et al, 2014). These studies provide useful information on food safety and potential of soil remediation of these plants.…”

Heavy metal (HM) pollution is a global environmental problem that threatens ecosystem and human health. Cadmium (Cd) pollution is the most prominent HM pollution type because of its high toxicity, strong migration, and the large polluted area globally. Phytoremediation of contaminated soil is frequently practiced because of its cost-effectiveness and operability and because it has no associated secondary pollution. High-accumulation plants, including those identified as hyperaccumulators, play an important role in phytoremediation. Therefore, screening of plants to identify hyperaccumulators is important for continued phytoremediation. In the present study, we investigated the Cd tolerance and accumulation capabilities of 18 turnip landraces from China under a soil experiment with known Cd level. The results indicated that turnip has a high capacity for Cd accumulation. Furthermore, significant differences in Cd tolerance and accumulation characteristics were found among different landraces when they grew at 50 mg kg-1 (dry weight) Cd concentration. Among the studied landraces, five turnip landraces met the requirements of Cd hyperaccumulators and three landraces were identified as potential candidates. However, the total Cd content accumulated by individual plant of different turnip landraces was dependent on both the Cd accumulation capacity and plant biomass. Compared with some reported Cd hyperaccumulators, turnip not only shows a high Cd-accumulation capacity but also has rapid growth and a wide distribution area. These advantages indicate that turnip may have considerable potential for phytoremediation of Cd-contaminated soil. Furthermore, the study also indicates that it is not advisable to consume turnip cultivated in an environment that exceeds safe Cd levels.

“…Molecular hydrogen plays a cytoprotective role by exerting protective effects against plant oxidative damage through the regulation of ROS homeostasis [9,10,11,12,13,14,18,19,20,21]. In this study, we showed that hydrogen treatment raised the frequency of active pro-embryogenic cells and normal somatic embryos at the PEM and SE phases, respectively (Figure 1).…”

“…In plants, the protective roles have also been proven when seeds, seedlings, explants, and fruits were subjected to hydrogen treatment with hydrogen-rich water or media [9,10,11,12,13,14,18,19,20,21]. However, the biological effects of exogenous hydrogen on plant cells in vitro cultures have not been documented to date.…”

Hydrogen is a therapeutic antioxidant that has been used extensively in clinical trials. It also acts as a bioactive molecule that can alleviate abiotic stress in plants. However, the biological effects of hydrogen in somatic embryos and the underlying molecular basis remain largely unknown. In this study, the morphological and physiological influence of exogenous H2 treatment during somatic embryogenesis was characterized in Larix leptolepis Gordon. The results showed that exposure to hydrogen increased the proportions of active pro-embryogenic cells and normal somatic embryos. We sequenced mRNA and microRNA (miRNA) libraries to identify global transcriptome changes at different time points during H2 treatment of larch pro-embryogenic masses (PEMs). A total of 45,393 mRNAs and 315 miRNAs were obtained. Among them, 4253 genes and 96 miRNAs were differentially expressed in the hydrogen-treated libraries compared with the control. Further, a large number of the differentially expressed mRNAs and miRNAs were related to reactive oxygen species (ROS) homeostasis and cell cycle regulation. We also identified 4399 potential target genes for 285 of the miRNAs. The differential expression data and the mRNA-miRNA interaction network described here provide new insights into the molecular mechanisms that determine the performance of PEMs exposed to H2 during somatic embryogenesis.
