    • Abstract

       

      Internal Ribosome Entry Site (IRES) sequences have been widely used to link the expression of two independent proteins on the same mRNA transcript. Genes encoding fluorescent proteins or drug-resistance enzymes are usually placed downstream of IRES, serving as expression indicators or selection markers. In biological applications where the upstream gene-of-interest is to be expressed at extremely high levels, it is often desirable to purposely reduce IRES downstream gene expression to economize the cellular resources and/or to generate more stringent selection pressure. Here we describe a miniature IRES mutant sequence (IRESmut3) with dramatically diminished co-translational efficiency to fulfill these purposes.

      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
