FIGURE S1 Rectangular phylogenetic maximum likelihood tree based on sequences of 62 different bacterial strains with homology to RebB from Cb. taeniospiralis. Reb proteins of the species studied here are highlighted. Numbers on branches show ultra-fast bootstrap values. Scale bar: the estimated proportional sequence divergence. Abbreviations: ct, Cb. taeniospiralis; cv, Cm. varicaedens; ra, Ro. alexandrii; pc, Ps. chlororaphis; aa, Ac. avenae; ht, Hy. taeniospiralis; mm, Ma. mediterranea.
FIGURE S2 Transmission electron microscopy images. (A) Tubular phage-like structures in the Ps. chlororaphis isolate. (B) Ps. chlororaphis R-body with extreme height. (C) Transition between two distinct layers (arrow) seen on an R-body isolated from Ps. chlororaphis. (D) to (F) Ultra-thin sections of high-pressure frozen Cm. varicaedens cells with R-bodies in the macronucleus of P. caudatum. The white arrows mark the sheath. The orange arrow marks where either the sheath or the outer R-body lamella appears connected to the cell membrane.
