Figure 4 : Key bacterial functional categories associated with carbon export at 150 m at global scale.
From: Plankton networks driving carbon export in the oligotrophic ocean
A bacterial functional network was built based on orthologous group/gene (OG) relative abundances using the WGCNA methodology (see Methods) and correlated to classical oceanographic parameters. Two functional subnetworks (FNET1 (n = 220) and FNET2 (n = 441), respectively, Extended Data Fig. 3a) are significantly associated with carbon export (FNET1: r = 0.42, P = 4 × 10−9 and FNET2: r = 0.54, P = 7 × 10−6, see Extended Data Fig. 3b). Higher functional categories are depicted for functions with a VIP score >1 (PLS regression, LOOCV, FNET1 R2 = 0.41 and FNET2 R2 = 0.48, see Extended Data Fig. 3d) in both subnetworks.
