Expression

Organism	Comment	Expression
Brassica rapa	downregulation of expression of chlorophyll degradation related genes, pheophytinase (BrPPH), pheophorbide a oxygenase (BrPAO), and RCC reductase (RCCR) by 6-benzyl aminopurine. After 7 days, leaves in 6-BA treatment display lightly yellowing, while the entire cabbages, except for the young leaves at the top, in control leaves turn yellow	down
Brassica rapa	Chl degradation in ethylene-treated cabbage is faster than it is in control leaves, strong activation in the expression of the enzyme, as well as of the other two chlorophyll degradation related genes, pheophytinase (BrPPH) and pheophorbide a oxygenase (BrPAO), in control and ethylene-treated leaves. After 7 days, leavese the entire cabbages, except for the young leaves at the top, in control and ethylene treatment turn yellow	up

General Information

General Information	Comment	Organism
physiological function	the expression of BrPPH, BrPAO and BrRCCR, and the activity of Mg-dechelatase is closely associated with the chlorophyll degradation during the leaf senescence process in harvested Chinese flowering cabbages under dark conditions	Brassica rapa
