Transcriptome Analysis Reveals Candidate Genes Related to Color Fading of 'Red Bartlett' (Pyrus communis L.).

ABSTRACT: The red color of fruit is an attractive plant trait for consumers. Plants with color-faded fruit have a lower commercial value, such as 'Red Bartlett' pears (Pyrus communis L.) that have dark-red fruit in the early stages of fruit development that subsequently fade to red-green at maturity. To identify the reason for color fading, we first analyzed the anthocyanin content of peel from 'Red Bartlett,' which displays the color fading phenomenon, and 'Starkrimson,' which has no color fading. Results showed that the anthocyanin content of 'Red Bartlett' peel decreased significantly late in fruit development, while in 'Starkrimson' there was no significant decrease. Next, RNA-Sequencing was used to identify 947 differentially expressed genes (DEGs) between 'Red Bartlett' and 'Starkrimson
