High rates of apoptosis visualized in the symbiont-bearing gills of deep-sea Bathymodiolus mussels
Fig 4
Percentages of apoptotic nuclei in the bacteriocyte zone of B. azoricus (Ba) and B. puteoserpentis (Bp) from the three sites.
White-colored boxplots indicate specimens collected non-isobarically, and grey boxplots indicate those collected isobarically, respectively. Percentages were not significantly different (a, see materials and methods). The letter n indicates the number of individuals analyzed for each species. Boxplot whiskers correspond to minimal and maximal values on a single image, the line inside the box is the median, and the upper and lower frames of the boxes represent the first and third quartile respectively.
