Population variability of triple symbiotic system: Paramecium bursaria-zoochlorella-and algophages
The triple symbiotic system (TSS): P. bursaria-Chlorella-Chlorovirus, was studied. In Eurasia we found only 2 forms TSS, named N, northern and S, southern ecotypes. Each ecotype manifested at 32°C ts (N)-or tr (S)-phenotypes. In northeren parts of P. bursaria areals, from Karelia up to Kamchatka, near Baikal and in Armenia highlands, we find only ts-viruses, in Central Asia - only tr-types. Two types of genome characters were shown by PCR of 18 S RNA-genes. According all this characters populations of zoochlorella in P. bursaria - 2 clones of obligate symbionts
