Trends in endogenous phytohormone contents and their biosynthetic enzymes/genes during storage root development. a The content of IAA during storage root development. b The trend of NIT4 (nitrile aminohydrolase 4 gene, Tai6. 54,353) expression in transcriptome (black points and lines) and proteome (colored boxes), as well as its qRT-PCR validation (grey bars). c The content of CTK during storage root development. d The trend of APRT (adenine hosphoribosyl transferase gene, Tai6. 15,689) expression in transcriptome (black points and lines) and proteome (colored boxes), as well as its qRT-PCR validation (grey bars). e The content of GAs during storage root development. f The trend of GA3ox4 (gibberellin 3-β-dioxygenase 4 gene, Tai6. 38,158) expression in transcriptome (black points and lines) and proteome (colored boxes), as well as its qRT-PCR validation (grey bars). g The content of JA during storage root development. h The trend of OPR3 (OPDA reductase 3 gene, Tai6. 23,209) expression in transcriptome (black points and lines) and proteome (colored boxes), as well as its qRT-PCR validation (grey bars). i The content of ABA during storage root development. j The trend of AAO (ABA-aldehyde oxidase gene, Tai6. 2076) expression in transcriptome (black points and lines) and proteome (colored boxes), as well as its qRT-PCR validation (grey bars). FPKM (fragments per kolibase of transcript per million fragments mapped) values were used to represent the relative expression of genes in transcriptome. FC (fold change) values were used to represent the relative expression of proteins in proteome
