Method for controlling nitrogen assimilation and disease tolerance of plant using AtSIZ1 gene

摘要

PURPOSE: A method for controlling nitrogen assimilation and disease tolerance using AtSIZ1 gene is provided to suppress the expression of the gene and to enhancing disease tolerance. CONSTITUTION: A method for controlling nitrogen assimilation in a plant comprises: a step of transforming a plant cell with a recombinant plant expression vector containing Arabidopsis thaliana-derived AtSIZ1 gene having a base of sequence number 1 to control AtSIZ1 expression; and a step of overexpressing AtSIZ1 genes. A plant with regulated nitrogen assimilation is prepared by transforming the gene with the recombinant expression vector. A composition for controlling nitrogen assimilation in a plant contains the AtSIZ1 gene.
