Altered expression of genes in lycopene biosynthesis and metabolism pathway in SlIPT4-RNAi orange fruits. The relative level of transcripts were detected via qRT-PCR between wild-type and SlIPT4 RNAi lines. The data of wild-type (WT) were taken as reference and normalized to 1. Each value represents mean ± SE of three replicates. Asterisks represent significant differences between SlIPT4-RNAi line and wild-type control (*P < 0.05, **P < 0.01, Student’s t test)
