GENES ENHANCING RESISTANCE TO STRESS AND USES THEREOF

摘要

PURPOSE: A composition containing SaDhn gene is provided to enhance resistance to osmotic stress or freezing stress and to improve plant productivity. CONSTITUTION: A Suaeda asparagoides-derived dehydrin SaDhn Suaeda asparagoides dehydrin protein has an amino acid of sequence number 2. A gene encoding SaDhn protein has a base sequence of sequence number 1. A composition for enhancing resistance to osmotic stress and freezing stress in a plant contains the SaDhn gene. A method for enhancing resistance to osmotic stress or freezing stress comprises a step of transforming a recombinant vector containing SaDhn gene into a plant and a step of expressing the SaDhn gene.
