Phosphorus-Solubilizing Bacteria Enhance Cadmium Immobilization and Gene Expression in Wheat Roots to Reduce Cadmium Uptake

Plants, Journal Year: 2024, Volume and Issue: 13(14), P. 1989 - 1989

The application of phosphorus-solubilizing bacteria is an effective method for increasing the available phosphorus content and inhibiting wheat uptake heavy metals. However, further research needed on mechanism by which inhibit cadmium (Cd) in roots its impact expression root-related genes. Here, effects strain Klebsiella aerogenes M2 Cd absorption detoxification immobilization genes were determined. Compared with control, reduced (64.1–64.6%) roots. fluorescence staining revealed that blocked entry exogenous into root interior enhanced cell walls. Forty-seven related to detoxification, including encoding peroxidase, chalcone synthase, naringenin 3-dioxygenase, upregulated Cd+M2 treatment. Strain resistance activity through regulation flavonoid biosynthesis antioxidant enzyme activity. Moreover, regulated phenylalanine metabolism MAPK signaling pathway enhance These results provide a theoretical basis use remediate Cd-contaminated fields reduce wheat.

Nitrogen affects and genotypic variation in Cd absorption, translocation and chemical forms in wheat

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Reasonable nitrogen (N) and low grain cadmium (Cd) accumulators can effectively reduce Cd content in wheat; however, the underlying mechanism remains unclear. This study aimed to investigate N affects genotypic variation absorption, translocation chemical forms (Chuannong30) high (Chuanmai88) grain-Cd-accumulating wheat. Pot experiment was arranged a completely randomized design consisting of two-factors: two levels (low, 0.5 mg∙kg^-1; high, 1.5 mg∙kg^-1) six treatments (0, 45, 90, 135, 180, 225 kg∙ha^-1). The results showed that both cultivars be grown low-Cd soil under fertilization rate 180 kg∙ha^-1, without toxicity issues; grain-Cd accumulating high-Cd rates < 135 toxicity. Increasing improved distribution cultivars, with higher effect observed Chuanmai88, lower concentrations Chuannong30 may attributed root absorption from leaf grain. increased all (except residual-Cd) especially condition, fractions extracted by 80% ethanol were predominant proportions also Chuanmai88 than Chuannong30. Moreover, increasing significantly decreased pH, exchange capacity bioavailability, resulting accumulation plants, promoted activation migration soil.
