    • Abstract

       

      We have isolated and purified two parental homodimers and a unique heterodimer of acid phosphatase [coded byAcph-11.05(F) andAcph-10.95(S)] from isogenic homozygotes and heterozygotes ofDrosophila malerkotliana. F andS produce qualitatively different allozymes and the two alleles are expressed equally within and across all three genotypes andF andS play an equal role in the epigenetics of dominance. Subunit interaction in the heterodimer over a wide range of H+ concentrations accounts for the epigenetics of dominance for enzyme activity

      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
