WebFeb 1, 2009 · PCR for the target gene is shown by coloured lines and PCR for the reference gene by dotted lines. Each colour corresponds to a cDNA sample. C is the threshold, a constant fluorescence intensity, used to determine each CT. (B) Data generated by qRT-PCR are used to assess quantitatively the expression of a target gene. WebApr 10, 2024 · Deletion and insertion of nucleotides in target sites of both TH and Yellow are detected in both F0 individuals and the inheritable F1 progenies. We confirm that TH and yellow-y are down-regulated in mutants by quantitative real-time PCR analysis. Compared with the control group, mutations of TH and yellow-y genes result in defects in …
