Effects of rba mutations and in trans expression of rba genes on R. capsulatus colony forming unit numbers in stationary phase. The ratios of viable cells ml-1 relative to SB1003 were determined as an average of 3 biological replicates with the same cultures used for the RcGTA gene transfer activity assays and western blots. Error bars represent standard deviation, and statistically significant differences (relative to wild type) were identified by analysis of variance (ANOVA) and are indicated by an asterisk (*; pā€‰<ā€‰0.05) or two asterisks (**; pā€‰<ā€‰0.1).
