    • Abstract

       

      Monoaminergic modulation of insect flight is well documented. Recently, we demonstrated that synaptic activity is required in serotonergic neurons for Drosophila flight. This requirement is during early pupal development, when the flight circuit is formed, as well as in adults. Using a Ca2+-activity-based GFP reporter, here we show that serotonergic neurons in both prothoracic and mesothoracic segments are activated upon air-puff-stimulated flight. Moreover ectopic activation of the entire serotonergic system by TrpA1, a heat activated cation channel, induces flight, even in the absence of an air-puff stimulus.

      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
