Anti-oxidant modulation in response to gamma radiation induced oxidative stress in developing seedlings of Psoralea corylifolia L.

► This manuscript points for the first time over expression of antioxidant enzymes to variable doses of gamma rays with corresponding increase in psoralen content in Psoralea corylifolia L. ► Decline in lipid peroxidation and proline accumulation was concomitant with psoralen increment describing the potential of Psoralen as antioxidant. ► Survival of plants following higher dosage of gamma-radiation (15 and 20 kGy) describes the radio resistivity of Psorelea seeds.
