The influence of transsulfuration gene-expressing Acetobacter on fly life span and methionine content. (A) The influence of CBS::CGL-expressing bacteria on dietary methionine content; n = 6 readings per treatment. *, P < 0.05. (B) Mean life spans of female (F) and male (M) flies bearing wild-type (WT) or CBS::CGL-expressing bacteria (+CGS-CGL). *, P < 0.05 versus female flies bearing wild-type (WT) bacteria.
