    • Abstract


      Uptake of Co2+ by cobalt-resistant strain is dependent on Co2+ concentration in the medium and is linear with time. The uptake is unaffected by metabolic inhibitors and decreased at low pH values. The uptake is independent of temperature in the range 0–40‡ C. The transport system is a passive diffusion process, unlike in the parent wild type strain where it is energy-dependent. It is possible that Mg2+ transport system is not involved in Co2+ transport in this strain, since the Co2+ uptake is not suppressed by Mg2+ as in the parent strain.

      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
