Fig. 4: Highly transcribed genes in Ca. C. neptuna and the proposed metabolic interaction between Ca. C. neptuna and P. oceanica.
From: Terrestrial-type nitrogen-fixing symbiosis between seagrass and a marine bacterium
a, The circular Ca. C. neptuna genome with GC content (grey), GC skew (purple/green) and the average transcription of protein-coding genes plotted as transcripts per million (TPM) (orange; TPM values above 1,000 were cut off). Note that most of the highlighted genes related to key metabolic functions have average TPM values of >1,000. A list of gene names and corresponding enzymes is provided in the Supplementary Information. b, Schematic of the symbiotic interaction between Ca. C. neptuna (magenta) and P. oceanica indicating the transfer of fixed N from N2 fixation (dark red arrows) and plant-derived sugars (black arrows); the potential for further plant growth promotion and defence mechanisms is also indicated. ROS, reactive oxygen species.
