PLANT HAVING IMPROVED TOLERANCE TO VARIOUS ENVIRONMENTAL STRESSES, METHOD OF CONSTRUCTING THE SAME AND POLYAMINE METABOLISM-RELATING ENZYME GENE

摘要

An isolated plant-origin polyamine metabolism-relating enzyme gene characterized by showing a change in expression dose upon environmental stresses in the polyamine metabolism in a plant; an antisense DNA or an antisense RNA to this gene; a plant having improved environmental stress-tolerance which carries the above gene in a stable state and its offspring; a method of constructing the plant; a method of constructing a callus of the plant; a method of selecting a transgenic plant showing excellent growth compared with plants free from an exogenous polyamine metabolism-relating gene; and a microorganism and a plant which are transformed by the above gene.
