Outline of Final Research Achievements

A key question in symbiosis studies is how multiple organisms are integrated in a well-organized system through symbiosis. I used aphid-Buchnera symbiosis as a model to address this issue at molecular level. I focus on BCR peptides that are aphid lineage-specific secretion peptides I have discovered in the pea aphid genome. I found that these BCRs are expressed strongly and exclusively in the symbiotic organ called bacteriocytes. Our imaging data indicated that these peptides are secreted and then targeted to the endosymbionts. I also found BCRs have antimicrobial effects on E. coli and some other bacteria. Recently, antimicrobial peptide (AMP)-like peptides have been reported to function in the context of mutualism in other symbiotic systems such as Medicago-Rizobium symbiosis. AMP-like molecule such as BCRs should be a key to understand the principle in the symbiosis evolution.
