[PROBLEMS] Genes PTB1 and PTB related to arsenic tolerance Provided is a method for recovering and detoxifying arsenic in the environment using one gene. The present invention relates to a protein that suppresses the expression of a high-affinity phosphate transporter, and a gene PTB encoding the same. 1. A method for imparting arsenic resistance by destroying PTB1, and a method for recovering and detoxifying arsenic using arsenic-resistant algae having destroyed PTB1. In addition, PTB1 A method of conferring phosphorus accumulation ability by disrupting a gene, And a method for recovering phosphorus using the phosphorus-accumulating transformant obtained by this method. |
