From: Characterizing the microbiomes of Antarctic sponges: a functional metagenomic approach
Autotrophic carbon pathways present in Antarctic sponge symbionts and SW communities. Bubbles reflect abundance (RPKG) of each enzyme involved in Calvin cycle (a), reductive Krebs cycle (rTCA) (b), 3-hydroxypropionate/4-hydroxybutyrate (3HP/4HB) cycle (c), and Wood–Ljungdahl pathway (d). Orange bubbles represent microbiome associated with Myxilla sp., red bubbles Leucetta antarctica and green bubbles, SW. Enzymes colored in red indicate key functional genes in each cycle. Grey circles represent functions that are absent in the metagenomes.
