Coloration patterns of FZX and NMC and DEGs involved in chlorophyll degradation between the 2 cultivars. A) Images of FXZ and NMC fruits at various stages of coloration. Images were digitally extracted for comparison. Bars = 1 cm. B) DEGs involved in chlorophyll degradation identified in RNA-seq data in litchi pericarp. Chl, chlorophyll; NOL, NYC1 non-yellow coloring 1; CLH, chlorophyllase; PAO, pheophorbide a oxygenase; Pheide, pheophorbide; PPH, pheophytinase; RCC, red Chl catabolite; RCCR, RCC reductase; SGR, stay-green protein. Numbers in the blocks indicate gene expression level in RPKM based on RNA-seq analysis.
