蜡状芽孢杆菌的启动子捕获质粒pAD123，该质粒无启动子，其编码绿色荧光蛋白GFPmut3a的突变型，其针对荧光激活细胞分选进行优化Cormack，绿色荧光蛋白（GFP）的FACS优化突变体）。
   We constructed a promoter-trap plasmid, pAD123, for Bacillus cereus. This plasmid contains a promoterless gene that encodesa mutant version of the green fluorescent protein, GFPmut3a, that is optimized for fluorescence-activated cell sorting [Cormack, FACS-optimized mutants of the green fluorescent protein (GFP).
