Comparison of viral function with sponge nutritional strategy, microbial abundance and geographic location. Comparison of viral functional profiles across 15 coral reef sponge species revealed that viral functions correlate with host nutritional strategy (photosymbionts vs no photosymbionts), microbial abundance (high microbial abundance—HMA, vs low microbial abundance—LMA) and geographic location (Fig. 3). Differential representation of putative AMGs and accessory genes across these ecological traits likely match host ecology. For instance, cellulose biosynthesis genes were enriched in phototrophic sponges, nitrogen metabolism genes were enriched in HMA sponges whilst antibiotic synthesis genes were enriched in LMA sponges. Additionally, heavy metal resistance genes were enriched in Red Sea sponges, whilst herbicide/insecticide resistance genes were enriched in GBR sponge viromes
