Potassium uptake and transport is facilitated by KT/HAK/KUP transporters. In this study, we identified 16 putative K+-uptake transporter genes in peach (Prunus persica). To investigate the role of PpeKUP in maintaing K+ uptake, transport, and homeostasis, we applied abiotic stresses to peach seedlings and analysed physiological reactions and transcriptional responses of PpeKUP genes. The peach seedlings...
AbstractPhytochelatins (PCs) are cysteine‐rich peptides with high binding affinity for toxic metals. Expressing the PC synthase gene (PCS) in plant growth‐promoting bacteria may enhance its metal resistance and accumulation, consequently increasing phytoremediation efficiency in heavy metal pollution. In this study, PCS from Schizosaccharomyces pombe was cloned and expressed in Pseudomonas putida ...
Significant differences of Cd accumulation in root exist among radish genotypes. In this study, the genetic diversity was investigated with DNA-based markers in radish. Based on the UPGMA analysis, the 32 accessions were clustered into two groups, the group I mainly comprised Chinese cultivars, while the group II consisted of six accessions from abroad. The cultivars in group I could be divided into...
The effects of cadmium (Cd) stress with different periods on Cd accumulation and antioxidant enzyme activities in radish plants were investigated with hydroponic culture. Radish seedlings were treated with 50 mg-L-1 Cd2+ for periods of 0, 6, 12, 24, 48 and 96 h. The results showed that with the extension of Cd treatment, the Cd content in shoots and roots were increased, and most of the Cd accumulated...
