Buscoi <p>The Benchmarking Universal Single-Copy Ortholog (BUSCO) assessment tool is used, for eukaryotic and bacterial proteomes, to provide quantitative measures of UniProt proteome data completeness in terms of expected gene content. BUSCO scores include percentages of complete (C) single-copy (S) genes, complete (C) duplicated (D) genes, fragmented (F) and missing (F) genes, as well as the total number of orthologous clusters (n) used in the BUSCO assessment.</p> C:98.9%[S:97.5%,D:1.4%],F:0.8%,M:0.3%,n:639 rhizobiales_odb10

Bradyrhizobium sp. strain ORS278, a photosynthetic bacterium, nodulates the stems of the aquatic legume Aeschynomene senstivia, and was isolated in Senegal. Group I Bradyrhizobium form nodules on all stem-nodulating Aeschynomene species, and are known to contain the nodulation-inducing nodABC genes, whereas the photosynthetic group II strains (among them strain ORS278) are restricted to a few species. These photosynthetic Bradyrhizobia form a separate phylum and may be closer to Rhodopseudomonas than to non-photosynthetic Bradyrhizobia. There are no nod, nif or fix genes in ORS278, which therefore must initiate nodulation in a quite different fashion than the nod-containing nitrogen-fixing bacteria. Nodulation-deficient mutants of ORS278 have defects in purine biosynthesis, suggesting that some kind of purine, perhaps a cytokinin, may serve as the signal to induce nodulation. Despite this absence, nodules on Aeschynomene synthesize leghemoglobin, have nitrogenase activity and transfer fixed N2 into the plant host. Interestingly, these photosynthetic Bradyrhizobia naturally associate with a wild rice species, Oryza breviligulata that co-inhabits some tropical marshes of Africa with Aeschynomenes. Association with ORS278 increases production by up to 20%. Additionally strain ORS278 produces canthaxanthine, which has pharmaceutical, agro-alimentary, and cosmetic applications for its coloring and photo-protective properties (supplementary information from PubMed 11097925).
