Occurrence (A), secretory capacity (B), and α-diversity (C) of genes and transcripts for fungal peptidases. Micro, micro-mycobiome (0.8–5 μm); macro, macro-mycobiome (5–2000 μm). Box shows median and interquartile range (IQR); whiskers show 1.5 × IQR of the lower and upper quartiles or range; outliers extend to the data range. Statistics are based on Wilcoxon test, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, ns, not significant. SRF, surface; MXL, mixed layer; DCM, deep chlorophyll maximum; MES, mesopelagic
