“…Sorghum is able to remedicate Cd-contaminated soil, and the polluted plant tissues can be harvested and used in the production of ethanol gas, thereby preventing Cd pollution from re-entering the food chain. This means that sorghum could be a connection between phytoremediation and bioethanol production, achieving a win-win effect (Jia et al, 2017;Feng et al, 2018;Mishra et al, 2020). Thus, it is essential to understand Cd toxicity in this species, and its response to Cd.…”

“…In recent years, multi-omics analysis technologies have been widely utilized to study the mechanisms underlying plant responses to abiotic stress. Transcriptomics and metabolomics represent powerful tools to comprehensively analyze the biological processes and their metabolic regulation in plants growing in stressful environments (Mishra et al, 2020;Feng et al, 2021). In this study, an integrated morpho-physiological analysis combined with transcriptomics and metabolomics was performed to gain insights into the molecular mechanisms underlying sorghum responses to Cd stress.…”

Cadmium (Cd) pollution is a serious threat to plant growth and human health. Although the mechanisms controlling the Cd response have been elucidated in other species, they remain unknown in Sorghum (Sorghum bicolor (L.) Moench), an important C4 cereal crop. Here, one-week-old sorghum seedlings were exposed to different concentrations (0, 10, 20, 50, 100, and 150 μM) of CdCl2 and the effects of these different concentrations on morphological responses were evaluated. Cd stress significantly decreased the activities of the enzymes peroxidase (POD), superoxide dismutase (SOD), glutathione S-transferase (GST) and catalase (CAT), and increased malondialdehyde (MDA) levels, leading to inhibition of plant height, decreases in lateral root density and plant biomass production. Based on these results, 10 μM Cd concentration was chosen for further transcription and metabolic analyses. A total of 2683 genes and 160 metabolites were found to have significant differential abundances between the control and Cd-treated groups. Multi-omics integrative analysis revealed that the flavonoid biosynthesis pathway plays a critical role in regulating Cd stress responses in sorghum. These results provide new insights into the mechanism underlying the response of sorghum to Cd.

Rusty soil is a waste from sand filtration of groundwater, but it is improperly disposed of thereby resulting in environmental contamination. Therefore, the possibilities of cleaning up the rusty sand by phytoremediation was examined. However, given that the rusty sand is rich in iron, the possibilities of iron biofortification of crops using sorghum as a model was assessed. Sorghum plants were transferred to treatment (variable mixtures of rusty sand, sand, and manure) and control soils (rusty sand and sand) and concentration of iron was ascertained at six and thirty days after transplanting (DAT). Iron concentration in plant parts were also determined at 30 DAT and soil iron reduction, bioconcentration (BCF) and translocation factors (TF) were computed. Statistical analyses (p < 0.05) showed that the highest considerable reduction in iron was achieved with the positive control that, however, produced a lower iron concentration in plant parts. But plants in 75% three-components mixture had the highest iron concentration in plant parts. Therefore, the 75% three-component mixture was best suited for iron biofortification of vegetative plant parts. The BCF and TF were respectively below and above one (TF in leaf) and phytostabilisation/exclusion and phytoextraction/phytoaccumulation of iron were inferred.
