H. Hosoya et al., SYMBIOTIC ALGAE-FREE STRAINS OF THE GREEN PARAMECIUM PARAMECIUM-BURSARIA PRODUCED BY HERBICIDE PARAQUAT, Zoological science, 12(6), 1995, pp. 807-810
The green paramecium, Paramecium bursaria, has endosymbiotic algae in
the cytoplasm. Here, we report that all endosymbiotic algae are destro
yed, producing symbiotic algae-free strains of paramecia, when green p
aramecia are cultivated in the presence of a herbicide paraquat.
