reduction in enzyme activity in transgenic Nicotiana tabacum plants is accompanied by the reduction in total chlorophyll and tocopherol content and the accumulation of geranylgeranylated chlorophyll. The presence of geranylgeranylated chlorophyll has no influence on harvesting and transfer of light energy in either photosystem. However, the reduced tocopherol content of the thylakoid membrane is a limiting factor for defensive reactions to photo-oxidative stress
