AbstractBacteria produce metamorphosis-associated contractile (MAC) structures to induce larval metamorphosis in Hydroides elegans. The distribution and diversity of mac gene homologs in marine environments are largely unexplored. In the present study mac genes were examined in marine environments by analyzing 101 biofilm and 91 seawater metagenomes. There were more mac genes in biofilms than in seawater, and substratum type, location, or sampling time did not affect the mac genes in biofilms. The mac gene clusters were highly diverse and often incomplete while the three MAC components co-occurred with other genes of different functions. Genomic analysis of four Pseudoalteromonas and two Streptomyces strains revealed the mac genes transfers among different microbial taxa. It is proposed that mac genes are more specific to biofilms; gene transfer among different microbial taxa has led to highly diverse mac gene clusters; and in most cases, the three MAC components function individually rather than forming a complex.
