SsDNA recombineering in L. lactis. a Activity of six recombinases when expressed exogenously in L. lactis. Recombineering utilized synthetic ssDNA introducing rifampin resistance. b Effects of various ssDNA dosages on recombination efficiency. Recombination frequencies significantly higher are indicated by an asterisk (*P < 0.05; **P < 0.01). The values are means ± standard deviations of three independent experiments
