From: Heterogeneous composition of key metabolic gene clusters in a vent mussel symbiont population
Distribution of symbiont subpopulations harbouring Locus_H or Locus_N in the gill. (a) Schematic drawing of the gill filaments. (b) Whole-mount in situ hybridization was performed for Locus_D, Locus_H and Locus_N (purple-blue signals). (c, d) Cross sections of gill filaments stained using fluorescence in situ hybridization and counterstained with DAPI staining (blue). (c) Double detection of Locus_D (green) and Locus_H (red). Lower panels show higher magnification. (d) Double detection of Locus_N (green) and Locus_H (red). Lower panels show higher magnification. For all panels in (b–d), frontal is to the top.
