Fig. 4From: Purification and partial characterization of LdtP, a cell envelope modifying enzyme in Liberibacter asiaticusLevel of expression of ldtPLc under osmotic stress conditions. The expression level of ldtPLc (B488_10900) was calculated against a control containing no added NaCl or sucrose and normalized with an internal standard, 16S rRNA. Values are given as the mean fold induction compared to the control with three biological replicates per condition. Statistical significance was determined using a Student’s t-test (*p < 0.05, **p < 0.01)Back to article page
