Provided is an amino acid optimization of a functional motif on an IrrE protein of astrain and homologous proteins thereof obtained by site mutation, wherein a second-site or fifth-site alanine in a functional domain motif 154LAELAR159 is mutated. into serine.

IrrE protein functional domain for improving anti-oxidation capability of cell and application thereof

A gene comprising the nucleic acid sequence of SEQ ID NO:1 and another gene comprising the nucleic acid sequence of SEQ ID NO:2, the latter being artificially synthesized according to plant preferred codons. Both genes encode a protein having the amino acid sequence of SEQ ID NO:3. Also provided are recombinant vectors containing each of the genes and host cells transformed with the recombinant vectors. The host cells can be prokaryotic cells [[and]] or eukaryotic cells. The transgenic plants comprising the gene having the nucleic acid sequence of SEQ ID NO:2 show improved salt and drought tolerance after the [[said]] gene is expressed in the transgenic plants.
