Abstract
The present disclosure relates to a gene expression regulation system of a Synechococcus elongatus PCC 7942. The gene expression regulation system of the S. elongatus PCC 7942 includes a S. elongatus PCC 7942 cell, a gene expression interference unit and a gene editing unit. The present disclosure also relates to a method for regulating a gene expression of the S. elongatus PCC 7942. The method includes providing the S. elongatus PCC 7942 cell, using the gene editing unit to insert an exogenous gene into the S. elongates PCC 7942 cell, and using the gene expression interference unit to inhibit an expression of a target gene.
