“…We found three QTL associated with the abundance of three genera: Lysobacter , Rheinheimera and Methylobacterium , all of which were observed to provide antimicrobial compounds [39], [40], [41], [42], [43], [44], [45], [46], [47]. These finding strongly suggests that host genotype influences abundance of specific commensal strains, and possibly targets their recruitment.…”

The commensal microbiota of fish skin is suspected to provide a protection against opportunist infections. The skin of fish harbors a complex and diverse microbiota that closely interacts with the surrounding water microbial communities. Up to now there is no clear evidence as to whether the host regulates the recruitment of environmental bacteria to build a specific skin microbiota. To address this question, we detected Quantitative Trait Loci (QTL) associated with the abundance of specific skin microbiota bacterial strains in brook charr (Salvelinus fontinalis), combining 16S RNA tagged-amplicon 454 pyrosequencing with genetic linkage analysis. Skin microbiota analysis revealed high inter-individual variation among 86 F2 fish progeny based upon the relative abundance of bacterial operational taxonomic units (OTUs). Out of those OTUs, the pathogenic strain Flavobacterium psychrophilum and the non-pathogenic strain Methylobacterium rhodesianum explained the majority of inter-individual distances. Furthermore, a strong negative correlation was found between Flavobacterium and Methylobacterium, suggesting a mutually competitive relationship. Finally, after considering a total of 266 markers, genetic linkage analysis highlighted three major QTL associated with the abundance of Lysobacter, Rheinheimera and Methylobacterium. All these three genera are known for their beneficial antibacterial activity. Overall, our results provide evidence that host genotype may regulate the abundance of specific genera among their surface microbiota. They also indicate that Lysobacter, Rheinheimera and Methylobacterium are potentially important genera in providing protection against pathogens.

“…Roseobacter had a higher abundance in the bloom area on day 3 (5.6 ± 0.49%), when algal density was lowest, but this is not as high as has been observed in other studies 11 18 72 73 . Most of the unique bacterial genera that appeared only in the bloom area are known to be associated with algal blooms: Winogradskyella is heterotrophic and many isolates are associated with algae 74 75 and phytoplankton blooms 76 ; Aureispira was was found during a Microcystis bloom 77 ; SAR202 clade organisms are ubiquitous and they usually occur in mesopelagic and deeper zones 78 79 , their appearance in the surface water of bloom areas indicate their presence is closely associated with DOM levels 78 ; Rheinheimera shows anti-algal activity 80 ; Roseovarius 81 and Bacillus 82 are also shown to have algicidal activity; Rickettsia 83 , Hoeflea 84 and Methylobacterium 85 can be symbiotic in algae; Dinoroseobacter may have a beneficial relationship with algae 86 and can be a symbiont of dinoflagellates 87 ; and Colwellia plays a key role in remineralizing organic matter generated from primary production 88 .…”

Although phytoplankton are the major source of marine dissolved organic matter (DOM), their blooms are a global problem that can greatly affect marine ecological systems, especially free-living bacteria, which are the primary DOM degraders. In this study, we analyzed free-living bacterial communities from Xiamen sea during an Akashiwo sanguine bloom using Illumina MiSeq sequencing of 16S rRNA gene amplicons. The bloom was probably stimulated by low salinity and ended after abatement of eutrophication pollution. A total of 658,446 sequence reads and 11,807 OTUs were obtained in both bloom and control samples with Alpha-proteobacteria and Gamma-proteobacteria being the predominant classes detected. The bloom decreased bacterial diversity, increased species evenness, and significantly changed the bacterial community structure. Bacterial communities within the bloom were more homogeneous than those within the control area. The bacteria stimulated by this bloom included the SAR86 and SAR116 clades and the AEGEAN-169 marine group, but a few were suppressed. In addition, many bacteria known to be associated with phytoplankton were detected only in the bloom samples. This study revealed the great influence of an A. sanguinea bloom on free-living bacterial communities, and provided new insights into the relationship between bacteria and A. sanguinea in marine ecosystems.

“…Regarding specific bacteria on the host plants (Fig.3), epiphytic bacterial communities of V. natans also contain bacteria closely related to those reported to have antibiotic ability, such as Janthinobacterium lividum, Cellvibiro and Rheinheimera (Granhall and Berg, 1972;Chen et al, 2010). Other species and groups found on V. natans are Acidovorax delafieldii, known for its ability to degrade polyhydroxyalkanoates (PHAs) (Brandi et al, 1995), Rhodobacter and Leadbetterella, which inhabit leaf surfaces of other aquatic angiosperms (Crump et al, 1999), and Planctomycete, a dominant component of a marine macroalga biofilm (Bengtsson and Øvreås, 2010).…”
