RT-qPCR assay of genes in tobacco and YC0136. Fluorescence RT-qPCR to verify the accuracy of the transcriptome data. One microgram of purified total RNA was used as template for first-strand cDNA synthesis. Several genes from RNA-seq were selected for amplification by SYBR green RT-qPCR. The GAPDH gene of strain YC0136 and the actin gene of tobacco were selected as references. Relative expression levels were calculated using the delta-delta Ct method. (A) RT-qPCR results for genes related to plant hormone transduction in tobacco. (B) RT-qPCR results for genes related to phenylpropane compound metabolism in tobacco. (C) RT-qPCR results for genes in strain YC0136. Three biological replicates were carried out, and three technical replicates were performed. Error bars indicate the SD from the mean.
