Fig. 7: Limnomonas gaiensis and prokaryotic bionts in cultures.

a: VR66-07, b: R86-47, c: VR66-10, and d: R86-45. Scale bar: 10 µm. Microalgal cells appeared red because of their chlorophyll autofluorescence, and their DNA in blue stained by DAPI. Prokaryotes, smaller in size, appeared blue by DNA staining and green in b (universal probe).
