Preliminary Study on Law of Cadmium Absorption and Transport at Rooting Stage of Lilium lancifolium
In order to explore the physiological response of Lilium lancifolium roots to cadmium stress,Lilium lancifolium was used as the experimental material,and hydroponic experiments at different concentrations were set up to compare the cadmium absorption and transport laws of Lilium lancifolium roots treated with different cadmium concentrations at the rooting stage,and the protein expression differences in the roots were compared.The results show that under cadmium stress,the bulbs of Lilium lancifolium do not enrich cadmium at the rooting stage,while the enrichment coefficient of Lilium lancifolium roots is greater than 1 at 20 μmol/L and above.The transport coefficient analysis shows that the transport capacity of bulbs to cadmium is very weak at the rooting stage of Lilium lancifolium,and the protein in the root of Lilium lancifolium is differentially expressed.These proteins include superoxide dismutase related to oxidative activity,isoflavone reductase related to isoflavone decomposition,and multifunctional regulatory enzyme nucleoside diphosphate kinase b.
