Expression of psa-pip was assessed in presence and absence of kiwi leaf extract for wild type (WT) and psaR2 mutant (Psa-mR2). Statistical analyses (Student’s t test) were performed to compare the significant difference in promoter analysis between wild type Psa strain and Psa-mR2 mutant in the presence and absence of kiwi extract. a, significant difference to b at P<0.01 and significant difference to c at P<0.05. c, not significant difference to c at P<0.05 but significant difference to a and b at P<0.05.
