Anthropogenic chromium (Cr) pollution in soils poses a great threat to human health through the food chain. It is imperative to understand Cr phytoavailability to rice (Oryza sativa L.), which is a major staple food crop for the largest population of people on Earth. This study was aimed to
The presence of chromium (Cr) in cultivated fields affects carbohydrate metabolism of rice (Oryza sativa L.) and weakens its productivity. Little is known about the molecular mechanism of sucrose metabolism underlying Cr stress response in rice plants. In the present study, the transcriptome
The effects of iron plaque formation on chromium (Cr) uptake and accumulation by rice seedlings (Oryza sativa L.) were assessed using hydroponic and soil experiments, where each 3 levels of Fe supplementation were added to Hoagland solution (0, 30, and 100 mg Fe2+ L-1) and a typical paddy soil (0,
MicroRNAs (miRNAs) are one of the most critical epigenetic regulators of gene expression which modulate a spectrum of development and defence response processes in plants. Chromium (Cr) contamination in rice imposes a serious concern to human health as rice is used as staple food throughout the
High chromium (Cr) in rice causes reduced yield and health hazards. This work investigates how Si alleviates Cr toxicity in rice. Addition of Si under Cr stress restored the growth parameters, total protein content, and membrane stability along with reduced Cr content in shoots, confirming that Si
CONCLUSIONS
Rice plants employ two strategies to cope with Cr toxicity: immobilizing Cr ions into cell walls to reduce its translocation and activating antioxidant defense to mitigate Cr-induced oxidative stress. The investigation aimed at understanding the physiological and proteomic responses of
High content of chromium in plants hampers plants' metabolism, disrupts plant growth and development. Therefore, improving plants' tolerance to Cr toxicity is very essential. In our present study, we investigated the role of citric acid (CA) on chromium detoxification in terms of stress tolerance in
Plants possess a well-organized protective network, wherein antioxidant enzymes play an important part in dealing with oxidative stress induced by over accumulation of ROS in plant cells. In the present study, a microcosm hydroponic experiment was performed to investigate the molecular modification
A hydroponic experiment was conducted to study the ameliorative effects of separate or combined application of exogenous glutathione (GSH), selenium (Se) and zinc (Zn) upon 20 μM cadmium (Cd) plus 20 μM chromium (Cr) heavy metal stress (HM) in rice seedlings. The results showed that HM caused a
Heavy metal uptake is confined by other elements, namely iron (Fe) and sulfur (S). There are yet no reports on the contribution of S supply to the attenuation of chromium (Cr) uptake when different species of Cr are employed. The bioaccumulation of Cr in two cultivars of rice seedlings subjected to
Chromium (Cr) is very toxic to both humans and plants. This investigation aimed to understand the physiological and molecular responses of rice seedlings to Cr stress. Cr toxicity did not significantly affect morphological features and Cr accumulation in roots and shoots in Pokkali but not in BRRI
Cytochrome c (CYTc) is one of the redox-active molecules responsible for electron transport in plant mitochondria. It is important in the interaction of metal ions with mitochondrial proteome, it is also essential for insights into electron transport during oxidative stress. This study focused on
The growths of two rice genotypes (Jin23A and CDR22) under the coexistence of As and Cr in solution culture with and without P were investigated. The result showed that rice shoot dry weight decreased due to the complex contamination of As and Cr, however, the influences on plant height, root length
Metallothioneins (MTs) is a metal ion binding protein to detoxify heavy metal stress in plant cells. This study examines involvement of MTs in metal chelation and ROS scavenging in rice seedling under Cr induction either Cr(VI) or Cr(III) at three different effective concentrations using Agilent 44K
In plants, cytochrome P450 monooxygenase (CYP) plays an important role in detoxifying xenobiotic chemicals and coordinating abiotic stresses. Agilent 44 K rice microarray has been used to focus on the transcriptional profile of osCYP genes in rice seedling exposed to Cr solution containing
