Fig. 7From: Integrated metabolomic and transcriptomic study unveils the gene regulatory mechanisms of sugarcane growth promotion during interaction with an endophytic nitrogen-fixing bacteriaqRT-PCR validation on the mRNA level of the key genes involved in the the flavonoid biosynthesis pathway. Relative mRNA levels of qRT-PCR were calculated using GAPDH as an internal control. R value in the top right of each figure indicates Pearson correlation coefficient between relative mRNA levels from qRT-PCR and transcriptome across stagesBack to article page
