    • Abstract

       

      Poly A enriched RNA from either liver or oviduct of estradiol-17β treated immature chicks supported [3H]-leucine incorporation into immunoprecipitable riboflavin carrier protein in a dose-dependent manner when translated in the rabbit reticulocyte lysate system. Primary translation product of riboflavin carrier protein had a molecular weight of 38,000 which on incubation with a stripped hepatic microsomal preparation was processed to a product with a size comparable to native riboflavin carrier protein. Poly A enriched RNA from both the liver and the oviduct of estrogen-treated birds stimulated [3H]-leucine incorporation into riboflavin carrier protein and this was 2–3 fold higher during secondary stimulationvis-a-vis primary stimulation with the steroid. Poly A enriched RNA from the liver of progesteronetreated birds during secondary stimulation did not support riboflavin carrier protein synthesis. In contrast, poly A enriched RNA from the oviduct of the birds treated with progesterone during secondary (but not primary) stimulation did exhibit riboflavin carrier protein-mRNA activity which was comparable to that stimulated by estradiol-17β

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
