COMPOSITION FOR INCREASING TOLERANCE TO COLD AND OXIDATIVE STRESS OF PLANTS

摘要

A composition comprising an MsrB3(Methionine Sulfoxide Reductase B3) gene or its protein is provided to increase tolerance against cold and oxidative stress, and reduce the contents of MetO(Methionine sulfoxide) and ROS(reactive oxygen species) increased at low temperature in plants, so that the production amount and yield of plants are increased. A composition for increasing increase tolerance against cold and oxidative stress in plants comprises an MsrB3 gene encoding the amino acid sequence of SEQ ID NO:2 or a protein encoded thereby. The tolerance against cold and oxidative stress in plants is increased by transforming a host cell with a recombinant vector containing the MsrB3 gene, and overexpressing the MsrB3 gene in the host cell.
