GENE INVOLVED IN ARSENIC TOLERANCE

摘要

PROBLEM TO BE SOLVED: To provide a gene PTB1 involved in arsenic tolerance, and to provide a method for recovering and detoxifying arsenic in the environment utilizing the gene.;SOLUTION: A protein inhibiting the expression of a transporter having high affinity for phosphoric acid, the gene PTB1 encoding the same, a method for giving arsenic tolerance by disrupting the gene PTB1, and a method for recovering and detoxifying arsenic using arsenic-tolerant algae with disrupted PTB1, are provided, respectively. A method for giving the ability to accumulate phosphorus by disrupting the gene PTB1, and a method for recovering phosphorus using a phosphorus-accumulative transformant obtained by the former method, are also provided, respectively.;COPYRIGHT: (C)2003,JPO
