Fig. 3From: Assessment of reference gene stability in Rice stripe virus and Rice black streaked dwarf virus infection rice by quantitative Real-time PCRExpression levels of candidate reference genes. a Average cycle threshold (Ct) values for the 14 candidate reference genes used in this study; b Comparison of the expression levels of candidate reference genes in different treatments (Con: virus-free SBPHs infection; RSV: RSV SBPHs infection; RBSDV: RBSDV SBPHs infection). 14-day-old rice seedlings were inoculated with or without viruliferous nymphs (RSV and RBSDV) for 3Â days. Total RNA was extracted from RSV- and RBSDV-infected seedlings, respectively. Values were given in the form of RT-qPCR quantification cycle numbers across all tested samples.
