    • Abstract

       

      Azospirillum brasilense, an associative diazotrophs from sorghum roots grows autotrophically on NH4+ and CaCO3. NH4+ a is also oxidized to NO2- and then denitrified. Addition of malate to the autotrophic medium enhances both NH4+ oxidation as well as NONH2- dissimilation. The incomplete nitrification linked denitrification results in a rapid loss of nitrogen from the growth medium. The bacterium also shows assimilatory NO3- and NO2- reductases and fixes nitrogen at 50 μg N/ml of NH4+ NO3- or NO2-

      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
