Method for regulating phototaxis under UV-A illumination in Synechocystis sp. PCC 6803 using the LsiR gene

摘要

PURPOSE: A method for regulating phototaxis with respect to UV-A using Synechocystis sp. PCC 6803 LsiR(Light and Stress Integrating Regulator) gene is provided to identify the expression and regulation of a gene by UV-A. CONSTITUTION: A method for regulating phototaxis with respect to UV-A using Synechocystis sp. PCC 6803 LsiR gene comprises: a step of knocking out LsiR gene and inducing positive phototaxis in Synechocystis sp.; and a step of transforming the Synechocystis sp. with LsiR gene and inducing negative phototaxis. The phototaxis with respect to UV-A using Synechocystis sp. PCC 6803 LsiR gene is controlled by regulating the expression of Synechocystis sp. PCC 6803-derived LsiR gene. LsiR gene has a base sequence of a sequence number 3.
