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

due to its multifunctionality and weak hydrophobicity, it is suggested that in plastids the same geranylgeranyl reductase is recruited into the chlorophyll, the tocopherol and the phylloquinone pathways. The geranylgeranyl reductase gene is up-regulated during etioplast to chloroplast and chloroplast to chromoplast development

the transcription of geranylgeranyl diphosphate reductase is likely to be regulated during leaf development. Transcription is stimulated by light, but repressed by dark and cold stress. Geranylgeranyl diphosphate reductase expression is regulated by photosynthetic activity and is possibly involved in the defence response
