Expression of the phrA gene following 2.5 kJ/m2 UVC exposure to R. varieornatus

A value obtained from non-irradiated R. varieornatus was set as 1 and values were compared to this control value. Subsequent samples are compared in terms of -fold regulation to this value. Asterisks denote significant differences compared with control (One-way ANOVA; •••: P<0.001). Each value is the mean±SD (n = 3).
