Abstract

FLUORESCENT IN BLUE LIGHT (FLU) is a nuclear-encoded plastid protein that, after import and processing, becomes tightly associated with plastid membranes [ 1 ]. It controls chlorophyll biosynthesis by interacting directly with Glu tRNA reductase (HEMA1) [ 2 ]. It operates independently of heme and seems to selectively affect only the Mg(2+) branch of tetrapyrrole biosynthesis [ 3 ].
