Abstract
Amino acid and nucelotide sequences relating to the glutamate dehydrogenase (GDH) enzyme are described. The GDH enzymes descnred herein were discovered in the alga Chlorella sorokinina in the form of seven different inducible isoenzymes. These isoenzymes are found in the algae as chloroplast-localized hexamers composed of .alpha.- and .beta.-subunits. Plants transfromed with nucleotide sequences encoding the .alpha.- or .beta.-subunits of the enzyme show imrpoved properties, for example, increased growth and improved stress tolerance.
