Abstract
Transgenic alfalfa (Medicago sativa) expressing Mn-superoxide dismutas e cDNA tended to have reduced injury from water-deficit stress as dete rmined by chlorophyll fluorescence, electrolyte leakage, and regrowth from crowns. A 3-year field trial indicated that yield and survival of transgenic plants were significantly improved, supporting the hypothe sis that tolerance of oxidative stress is important in adaptation to f ield environments.
