Cloned(Commentary)

EC Number Cloned (Comment) Organism
2.4.1.14 gene SPS-1 or SPSA, overexpression in Medicago sativa driven by the constitutive CaMV35S promoter via Agrobacterium tumefaciens strain GV3101 transfection. Overexpression and increased activity of the enzyme in alfalfa is accompanied by early flowering, increased plant growth and an increase in elemental N and protein content when grown under N2-fixing conditions Zea mays
