pheophorbide a, a key intermediate of chlorophyll catabolism, causes cell death in complete darkness in a transgenic Arabidopsis plant, As-ACD1. Expression of mRNA for pheophorbide a oxygenase is suppressed by expression of Acd1 antisense RNA. As-ACD1 accumulates an excessive amount of pheophorbide a when chlorophyll breakdown occurs. When senescence is induced by a continuous dark period, leaves of As-ACD1 plants become dehydrated, phenotype, overview |
