Abstrakt: A sample from a 2019 cyanobacterial bloom in a freshwater reservoir in eastern Oregon, USA, was used to produce a metagenome from which the complete, circular 7.3 Mbp genome of Limnoraphis sp. WC205 was assembled. The Limnoraphis sp. WC205 genome contains gas vesicle genes, genes for N 2 -fixation and genes for both phycocyanin- and phycoerythrin-containing phycobilisomes. Limnoraphis was present in Willow Creek Reservoir throughout the summer and fall, coexisting with various other cyanobacteria in blooms that were associated with microcystin. The absence of cyanotoxin genes from the Limnoraphis sp. WC205 genome showed this cyanobacterium to be non-toxigenic, although it is predicted to produce cyanobactins closely related to Microcystis aeruginosa microcyclamides. DNA sequence corresponding to the Microcystis mcyG gene identified Microcystis as the microcystin producer in this lake.
