Phototrophic diversity. RAxML tree displaying 2141 tufA sequences of ‘Phototrophs’ (including OTUs) rooted with 556 sequences of ‘Heterotrophs’ (not shown) and based on an alignment of 891 bp. The tree was edited in iTOL for bootstrap support, OTU abundance (vertical bars topping dashed lines) and taxonomy (inner ring Phyla, outer ring Classes). A few phylogenetic landmarks are reported on the tree margin as well as stems leading to orders of the Ulvophyceae (Bryopsidales and ‘Ulvales-Ulothichales’)
