Proc Natl Acad Sci U S A. La nature biochimique de ces échanges n'a pas été déterminée. Les microalgues vivent à l'intérieur de la paramécie Paramecium bursaria, dans son cytoplasme par endosymbiose et les zoochlorelles fournissent de la nourriture, tandis que la paramécie fournit aux algues à la fois le mouvement et la protection. Paramecium (also Paramoecium, / ˌ p ær ə ˈ m iː ʃ (i) ə m /, PARR-ə-MEE-sh(ee-)əm, /-s i ə m /, -⁠see-əm) is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. To identify the unique sequence variants of each strain, we identified variations by GATK v4.0.3 [110] and used the H1 haplotype of the Dd1 strain as the reference genome. Google Scholar. Les péniculidés constituent un ordre de protozoaires ciliés, Peniculida, essentiellement avec les paramécies. 2, Academia Road, Nankang, Taipei, 115, Taiwan, Yu-Hsuan Cheng, Chien-Fu Jeff Liu, Yen-Hsin Yu, Yu-Ting Jhou & Jun-Yi Leu, Biodiversity Research Center, Academia Sinica, Taipei, 115, Taiwan, Graduate School of Sciences and Technology for Innovation, Yamaguchi University, Yamaguchi, 753-8512, Japan, You can also search for this author in PLoS Genet.
