We report here the metagenome-assembled draft genome of an uncultured filamentous anoxygenic phototroph of the phylum
Chloroflexota
(formerly
Chloroflexi
), “
Candidatus
Roseilinea sp. strain NK_OTU-006,” recovered from hot spring-associated microbial mats. The 3.6-Mb genome is estimated to be 94% complete and comprises 117 contigs encoding 3,203 predicted genes, including a full-length rRNA operon.
