The pathway of chlorophyll breakdown and expressions of chlorophyll breakdown genes. (A) The PAO pathway of chlorophyll breakdown. (B) A heat map of the expressions of genes for chlorophyll breakdown in the pericarp during coloration. Chl, chlorophyll; CLH, chlorophyllase; HCAR, hydroxy-Chl a reductase; MCS, metal chelating substance; NCCs, nonfluorescent Chl catabolites; NOL, NYC1-like; NYC1, non-yellow coloring 1; PAO, pheide a oxygenase; pFCC, primary fluorescent Chl catabolite; Pheide, pheophorbide; PPH, pheophytinase; RCC, red Chl catabolite; RCCR, RCC reductase; SGR, stay-green protein.
