Fig. 3From: Metagenome-assembled genomes reveal greatly expanded taxonomic and functional diversification of the abundant marine Roseobacter RCA clusterPhylogenetic tree of the PR gene and gene sequence of the PR operon detected in the RCA cluster. A Phylogenetic tree based on PR genes. B Gene sequence of the PR operon detected in the RCA cluster; Blh: 15,15′-β-carotene dioxygenase; crtY: lycopene cyclase; crtB: phytoene synthase; crtI: phytoene dehydrogenase; crtE: putative geranylgeranyl pyrophosphate (GGPP)Back to article page
