摘要
Senescence is a highly regulated recycling process in which nutrients are translocated from deteriorating leaves to newly developing leaves, flowers, seeds, or roots （Lim et al., 2007; Gregersen et al., 2013）. Chloroplast dismantling, a major event during senescence, involves the degradation of light-harvesting chlorophyll a/b-binding proteins （LHCPs） and the release of free chlorophyll （Chl） which is catabolized to phototoxic, cell-damaging Chl breakdown intermediates.
