Cadmium pollution now is one of the main environmental problems. Growing of plants hyper accumulators of Cd can help to remediate the polluted soils. Species Linum usitatissimum L. is one of such crops. Cadmium concentrations were analysed in the ashes of adult plants by x-ray fluorescence analyzer BRA – 18. The presence of pollutants did not influence flax germination ability, but tested genotypes showed different degrees of cadmium resistance.

The KAR1 treated seedlings showed improved gas exchange attributes and metal tolerance index. In summary, these findings advocate that KAR1 enhances plant stress tolerance by modulating the antioxidative machinery and reducing the level of stress biomarkers.

The variations of response could be signals of tolerance or adaptive mechanisms of the leaves under the determined concentrations. Deeper anatomic and physiological studies can contribute to the explanation of the role of cell epidermis of faba bean in its adaptation to ions of cadmium.

Metal tolerance is often an integrative result of metal uptake and distribution, which are fine-tuned by a network of signaling cascades and metal transporters. Thus, with the goal of advancing the molecular understanding of such metal homeostatic mechanisms, comparative RNAseq-based transcriptome analysis was conducted to dissect differentially expressed genes (DEGs) in maize roots exposed to cadmium (Cd) stress.

ABC1K (Activity of BC1 complex Kinase) is an evolutionarily primitive atypical kinase family widely distributed among prokaryotes and eukaryotes. The ABC1K protein kinases in Arabidopsis are predicted to localize either to the mitochondria or chloroplasts, in which plastid-located ABC1K proteins are involved in the response against photo-oxidative stress and cadmium-induced oxidative stress.

Hydrogen sulfide (H2S) is a gas signal molecule involved in regulating plants tolerance to heavy metals stress. In this study, we investigated the role of H2S in cadmium-(Cd-) induced cell death of root tips of cucumber seedlings.

This study was designed to investigate the efficacy of the biocontrol isolates on growth promotion and ability in lowering the metal uptake by rice plant (variety MTU 7029) with two Trichoderma isolates namely MT-4 and UBT-18 both having tolerance towards cadmium. Substantial variations had been found in different treatments.

Hydrogen gas (H2) is hypothesised to play a role in plants that are coping with stresses by regulating signal transduction and gene expression. Although the beneficial role of H2 in plant tolerance to cadmium (Cd) has been investigated previously, the corresponding mechanism has not been elucidated.

Oilseed rape is an excellent candidate for phytoremediation of cadmium (Cd) contaminated soils given its advantages of high biomass, fast growth, moderate metal accumulation, ease of harvesting, and metal tolerance, but the cadmium response pathways in this species (Brassica napus) have yet to be fully elucidated.

MicroRNAs (miRNAs) regulate numerous crucial abiotic stress processes in plants. However, information is limited on their involvement in cadmium (Cd) stress response and tolerance mechanisms in plants, including ramie (Boehmeria nivea L.) that produces a number of economic valuable as an important natural fibre crop and an ideal crop for Cd pollution remediation.

Our previous research defined two tomato (Solanum lycopersicum) genotypes: high cadmium (Cd) accumulator YSL189 and low Cd accumulator HZ903. Further hydroponics experiments investigated the different tolerance mechanisms to Cd stress between YSL189 and HZ903 at the seedling stage.

Wheat cultivars chosen for their cadmium (Cd) tolerance (Sönmez-2001) and sensitivity (Quality) were grown in Hoagland solution for 20 days and then they were treated with 100 µM 2-(4-carboxyphenyl)-4,4,5,5-tetramethylylimidazoline-1-oxyl (cPTIO), a nitric oxide (NO) scavenger, or with 100 µM sodium nitroprusside (SNP), a NO donor, with and without 9 mM Cd. NO, free polyamines and Cd levels were analysed by using leaf and root samples taken 24 and 72 h after treatment.

By using two durum wheat cultivars (Triticum durum L. cvs. Balcali-85 and C-1252) a nutrient solution experiment was carried out to study genotypic variation in cadmium (Cd) tolerance, Cd concentrations in plants, and the role of ascorbic acid and non-protein SH groups (SH: sulphydryl) in Cd tolerance.
