Removal of gut symbiotic bacteria negatively affects life history traits of the shield bug, Graphosoma lineatum
<p><span>Bacterial Symbionts play an important biological role in their host. <i>G. lineatum</i> harbor bacterial symbiont in the enclosed crypts of the midgut. It seems that the bacterial symbiont play important role in the insect. Therefore, in this study, the role of bacterial symbiont in the shield bug, <i>Graphosoma lineatum</i> (Heteroptera, Pentatomidae) was investigated. To do this symbiont elimination was performed using surface sterilization of the eggs. Then, we utilized <span>age-stage, two-sex life table analysis</span> to confirm the biological importance of bacterial symbiont in <i>G. lineatum</i>. According to our results symbiont removal had a significantly negative effect on the biology of the insect. These results clearly indicate this symbiont is essential for normal growth and reproduction.</span></p>

Toxin-producing endosymbionts shield pathogenic fungus against micropredators: Supplementary Information Videos
<p><strong>ABSTRACT</strong></p> <p>The fungus <em>Rhizopus microsporus </em>harbours a bacterial endosymbiont (<em>Mycetohabitans rhizoxinica</em>) for the production of the antimitotic toxin rhizoxin. Although rhizoxin is the causative agent of rice seedling blight, the toxinogenic bacterial-fungal alliance is, however, not restricted to the plant disease. It has been detected in numerous environmental isolates from geographically distinct sites covering all five continents, thus raising the question on the ecological role of rhizoxin beyond rice seedling blight.</p> <p>Here we show that rhizoxin serves the fungal host in fending off protozoan and metazoan predators. Fluorescence microscopy and co-culture experiments with the fungivorous amoeba <em>Protostelium aurantium</em> revealed that ingestion of <em>R. microsporus</em> spores is toxic to <em>P. aurantium</em>. This amoebicidal effect is caused by the dominant bacterial rhizoxin congener rhizoxin S2, which is also lethal towards the model nematode <em>Caenorhabditis elegans</em>. By combining stereomicroscopy, automated image analyses, and quantification of nematode movement we show that the fungivorous nematode <em>Aphelenchus avenae </em>actively feeds on <em>R. microsporus</em> that is lacking endosymbionts, while worms co-incubated with symbiotic <em>R. microsporus </em>are significantly less lively.</p> <p>This work uncovers an unexpected ecological role of rhizoxin as shield against micropredators. This finding suggests that predators may function as an evolutionary driving force to maintain toxin-producing endosymbionts in non-pathogenic fungi.</p> <p> </p> <p><strong>Legends for the Supplementary Information Videos</strong></p> <p><strong>Video S1</strong>.
