the geranylgeranyl diphosphate reductase mRNA is abundant in chlorophyll-containing tissues and flower organs, but barely detected in the roots and mesocarp of ripening fruits, suggesting that transcription is related to plastid types and maturation. mRNA is spread thoroughly in leaf cells during the early stages and is located mainly in the palisade of mature leaves, which exhibit higher transcript levels than young ones. Hence, 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. In wounded leaves, the message decreases, but recovers rapidly, whereas in curled leaves, a reduction in gene expression is related to leaf damage intensity |
