(a) Latitudinal variation in amoA expression (Log10 (transcripts l−1)) of shallow clade AOA, deep clade AOA, and βAOB at the 0.1% light depth (see dashed line in Figure 3b). Error bars indicate s.d.s of triplicate qPCR analyses. (b, c) Relationships at the 0.1% light depth between (b) amoA abundance of shallow clade AOA, deep clade AOA, and βAOB and ammonia oxidation and (c) amoA expression of shallow clade AOA, deep clade AOA and βAOB and ammonia oxidation.
