MeSH headings : 5' Untranslated Regions / genetics; Darkness; Ferredoxins / genetics; Light; Peas / genetics; Peas / radiation effects; Plant Leaves / genetics; Plant Leaves / metabolism; Plants, Genetically Modified / genetics; Plants, Genetically Modified / radiation effects; Polyribosomes / genetics; Protein Biosynthesis / radiation effects; RNA, Messenger / genetics; Tobacco / genetics; Tobacco / radiation effects
topics (OpenAlex): Photosynthetic Processes and Mechanisms; Plant Gene Expression Analysis; Plant Molecular Biology Research
TL;DR: Observations support a model in which Fed-1 mRNA in illuminated leaves is stabilized by its association with polyribosomes, and/or by translation, and that translation of other mRNAs is also rapidly down-regulated in response to darkness. (via Semantic Scholar)

2000 article

Premature termination codons destabilize ferredoxin‐1 mRNA when ferredoxin‐1 is translated

Petracek, M. E., Nuygen, T., Thompson, W. F., & Dickey, L. F. (2000, March 1). The Plant Journal, Vol. 21, pp. 563–569.

MeSH headings : Cells, Cultured; Codon, Terminator; Ferredoxins / genetics; Mutation; Peas / genetics; Peas / metabolism; Protein Biosynthesis; RNA, Messenger / metabolism
topics (OpenAlex): Photosynthetic Processes and Mechanisms; Light effects on plants; Plant Gene Expression Analysis
TL;DR: It is shown that the nonsense codon effect results primarily from lowering the Fed-1 mRNA stability in light-treated leaf tissue and in rapidly growing tobacco cell cultures, but not in dark- treated leaf tissue, suggesting that nonsense codons trigger a decay pathway distinct from that seen for Fed- 1 mRNA in the dark.

1998 article

Ferredoxin-1 mRNA is destabilized by changes in photosynthetic electron transport

Petracek, M. E., Dickey, L. F., Nguyen, T. T., Gatz, C., Sowinski, D. A., Allen, G. C., & Thompson, W. F. (1998, July 21). Proceedings of the National Academy of Sciences, Vol. 95, pp. 9009–9013.

MeSH headings : Diuron / pharmacology; Electron Transport; Ferredoxins / genetics; Half-Life; Histones / genetics; Photosynthesis / drug effects; Plants, Genetically Modified / genetics; Plants, Toxic; Promoter Regions, Genetic; RNA, Messenger / metabolism; Tetracycline / pharmacology; Tobacco / genetics
topics (OpenAlex): Photosynthetic Processes and Mechanisms; Legume Nitrogen Fixing Symbiosis; Plant Virus Research Studies
TL;DR: The tetracycline repressible Top10 promoter system is used to specifically shut off transcription of the Fed-1 transgene, and data indicate that cessation of photosynthesis, either by darkness or DCMU results in a destabilization of theFed-1 mRNA. (via Semantic Scholar)
