Figure 4.

Incorporation of carbon from Glc-6-P and pyruvate into fatty acids by plastids from developing embryos. Plastids from embryos at stages A, B, and C were incubated with Glc-6-P and pyruvate (both at 1 mm) either individually or together. When both substrates were supplied simultaneously, either [¹⁴C]Glc-6-P and ¹⁴C-pyruvate were supplied together or [¹⁴C]Glc-6-P was supplied with unlabeled pyruvate and vice versa. Labeled substrates are denoted by an asterisk. Incorporation is expressed on an acetate-equivalent basis. Each value represents the mean ± se of measurements made on three separate plastid preparations.
