FIGURE 2.

Co-cultivation pattern type 1 (symbiosis genes): No growth of the dinoflagellate in co-culture with the respective transposon mutant strains of D. shibae. Six examples are shown here. Growth of the dinoflagellate with the remaining 14 transposon mutants showing the same pattern can be found in Supplementary Figure 4. Controls are axenic cultures of P. minimum with/without B12, shown in black, and co-cultures with D. shibae wild-type and the Δ 191 plasmid mutant, shown in red.
