Abstract: The invention relates to a transgenic plant comprising a gene that confers resistance to oxidative stress in said plant, wherein said gene encodes an enzyme that has anti-oxidant activity or an enzyme that produces an antioxidant compound, and wherein said gene is under the control of a regulated promoter functional during the early ontogeny of said plant.

Abstract: The invention relates to method for increasing the yield of a plant grown under conditions that cause periodic oxidative stress in said plant, comprising the step of growing a seedling, tissue culture or plantlet into a plant, and further comprising the step of manipulating said plant or the environment of said plant such that an increase in the rate of respiration and/or protein turnover in said plant due to said periodic oxidative stress is intentionally prevented during the early ontogeny of said plant.
