Transcript levels of UGT genes in pomelo fruit during development and ripening. The pomelo UGT genes expression profiles of different fruit tissues were studied during three developmental stages: green stage at 80 days after full blossom (DAB), color breaking stage at 140 DAB, and mature stage at 200 DAB. The heat map was calculated by hierarchical clustering of UGT genes. The transcript abundance of UGT genes is represented by the color scale (representing − 2 to 2). Different letters indicate different phylogenetic groups of pomelo UGT genes
