Example of PCR on gill chamber epibionts of <i>R</i>. <i>exoculata</i>.
<p>(A) <i>luxS</i> amplification. <i>luxS</i> genes from <i>Vibrio harveyi</i> and <i>Vibrio parahaemoliticus</i> were used as negative controls. (B) <i>luxR</i> amplification on branchiostegite (br) and scaphognathite (sc) epibionts. (C) <i>luxR</i> amplification on gut (g) and stomach (st) epibionts.</p
<i>lux</i> gene PCRs on epibionts of <i>R</i>. <i>exoculata</i> juveniles and eggs.
<p>(A) <i>luxS</i> amplification on scaphognathite and eggs. (B) <i>luxR</i> amplification on scaphognathite and eggs. (C) <i>luxR</i> amplification on (br) branchiostegite and (sc) scaphognathite at the beginning (1) and end (2) of the molt.</p
<i>luxS</i> gene phylogeny (calculated on 550 bp) of symbionts associated with the gill chamber of <i>R</i>. <i>exoculata</i>.
<p>The robustness was tested using 500 bootstraps resampling the tree using the Neighbor-Joining algorithm with the Kimura two-parameter correction matrix. (A) <i>luxS</i> gene affiliated to <i>Proteobacteria</i>. (B) <i>luxS</i> gene affiliated to <i>Epsilonproteobacteria</i>. (C) Localizations of <i>R</i>. <i>exoculata</i> on hydrothermal vents and studied areas; red: Rainbow, green: TAG, blue: Snake Pit, orange: Logatchev (modified from [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174338#pone.0174338.ref071" target="_blank">71</a>]). Clone numbers are indicated between brackets.</p
Acquisition of symbionts in the gill chamber of <i>Rimicaris exoculata</i>.
<p>(A) Epibiontic colonization through the molt cycle [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174338#pone.0174338.ref022" target="_blank">22</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174338#pone.0174338.ref023" target="_blank">23</a>] compared to (B) biofilm formation [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174338#pone.0174338.ref032" target="_blank">32</a>].</p
PCR and RT-PCR (end of molt) amplification results per sample of different <i>Rimicaris exoculata</i> parts from different vent sites for the <i>luxR</i> gene analysis.

Example of <i>lux</i> RT-PCR on gill chamber epibionts of <i>R</i>. <i>exoculata</i>.
<p>Free RNAse/DNAse water was used as template for the negative control. (A) <i>luxS</i> amplifications were done on branchiostegite (br), scaphognathite (sc), and gut (g) shrimp epibionts at the end of molt cycle from Rainbow. A1 end of molt and A2 beginning of molt cycle (B) <i>luxR</i> amplification were done on branchiostegite (br), scaphognathite (sc), gut (g), eggs and juvenile (juv) epibionts at the beginning (B2) and at the end (B1) of the molt cycle. The dotted box indicates the correct PCR products size. B2 was more contrasted to try to observe any amplification.</p
