Phenotype and genotype ( spiddos ). Photomicrographs A1~E are of freshly collected organisms used in this study. Photomicrographs F~H were taken from published books [22, 23]. a) Photomicrographs of Rhizaria (A1~D2), diatom (E), fungi (F) and bacteria (G & H). The scale bars correspond to 100 Âµm (thick line) and 5 μm (thin line). b) Genome profiles (GP) of radiolarian-derived DNA. The directions of migration and temperature gradient are shown. The DNA band of the internal reference for each GP is shown. The small white circles indicate the featuring points termed species identification dots (spiddos). DNAs were fluorescently-labeled (left) or silver-stained (right). c) Normalized spiddos, which represent the genotype for each organism. Panels of A1 to H correspond to the same organisms as in Fig. 1a. The remaining 8 panels without pictures contain GPs for the organisms examined in this paper. GPs of A1-1 and D-2 are shown in Fig. 1b. The original data (i.e., genome profiles) for spiddos of panels Fig. 1c-F and -G were published in refs 13 and 19, respectively, newly processed to spiddos here. The sample foe the panel Fig. 1c-H is newly reported.
