Sea purslane SpJAZ7 gene and application thereof in improvement of cadmium tolerance of plants

The invention discloses a sea horse tooth SpJAZ7 gene and application of the sea horse tooth SpJAZ7 gene to improvement of cadmium tolerance of plants, and belongs to the field of gene engineering, and the nucleotide sequence of the sea horse tooth SpJAZ7 gene is shown as SEQ ID No.3. Under cadmium stress treatment, compared with a control group, the SpJAZ7 transgenic arabidopsis thaliana has certain cadmium tolerance. It is proved that the Sea Pinellia SpJAZ7 gene is helpful for improving the cadmium tolerance of a model plant arabidopsis thaliana, and the research provides a reference basis for the application of Sea Pinellia in the aspects of purification of heavy metal polluted soil and water bodies and the like. 本发明公开了海马齿SpJAZ7基因及其在提高植物对镉耐受性上的应用，属于基因工程领域，所述海马齿SpJAZ7基因的核苷酸序列如SEQ ID No.3所示。在镉胁迫处理下，与对照组相比，转SpJAZ7基因拟南芥具有一定的耐镉能力。证明海马齿SpJAZ7基因有助于提高模式植物拟南芥对镉的耐受性，该研究为海马齿用于重金属污染的土壤及水体的净化等方面提供参考依据。
