Expression of lcy-β1 and lcy-β2 in various tissues of papaya Hybrid 1B and Tainung. Relative levels of lcy-β1 and lcy-β2 mRNA from leaf, flower, colour-break (CB) fruit, and ripe (R) fruit of cultivars Hybrid 1B and Tainung were measured by qPCR using gene-specific primers. Expression data were normalized to the expression of 18S rRNA. Expression levels in each tissue are relative to the expression of lcy-β1 in leaf tissue of Hybrid 1B.
