Decarboxylation of [4-¹⁴C]Asp (12.5 mm) by BS strands at a PPFD of 200 μmol m⁻² s⁻¹ (white bars) or in the dark (black bars). The incubation medium for the control treatment contained 10 mm 2-oxoglutarate (2-OG) and 1 mm Mn²⁺. For the other treatments, 400 μm MPA, 10 mm ATP, or 1 mm Mg²⁺ was added and 2-oxoglutarate or Mn²⁺ was omitted. Data are means ± se of three assays.
