Functional redundancy for the metabolic exchange of siderophores, vitamins, nitrogen, and phosphorus underpins the interactions in the Trichodesmium consortium


ABSTRACT: Proteomic measurements from cyanobacteria colonies picked from the Gulf of Aqaba (Red Sea); analyzed to reveal interaction of cyanobacteria Trichodesmium and its taxonomically diverse microbial community partners. Samples were digested with trypsin, fractionated, and analyzed by LC-MS/MS. Data was searched with MS-GF+ using PNNL's DMS processing pipeline against a metagenomics FASTA file sequenced at JGI.

<h4>Importance</h4>Colonies of the cyanobacteria <i>Trichodesmium</i> act as a biological hotspot for the usage and recycling of key resources such as C, N, P, and Fe within an otherwise oligotrophic environment. While <i>Trichodesmium</i> colonies are known to interact and support a unique community of algae and particle-associated microbes, our understanding of the taxa that populate these colonies and the gene functions they encode is still limited. Characterizing the taxa and adaptive strate  ...[more]
