The qRT-PCR expression data of all structural genes: Early Biosynthetic Genes (EBGs), Late Biosynthetic Genes (LBGs) and Transcription Factors (TFs) analyzed in petals. The expression levels are calculated as the mRNA fold increase. Each accession is indicated by code: ‘Lima rossa corrugata’—LR, ‘Incomparabile’—LI, ‘Femminello Adamo’—FA, ‘Zagara bianca’—ZB, ‘Rangpur lime’—RaL, ‘Meyer’—LM, ‘Mexican lime’—LMT, ‘Diamante’—CD, C. volkameriana—CV, M. australasica var. sanguinea—MAS, ‘Tahiti’—LT, ‘Red lime’—RL, Citrus latipes—CL, ‘Pink fleshed’—PF, ‘Buddha’s hand’—MB, C. celebica—CC.
