TAG accumulation in WT plants under Pi-depleted growth conditions. (A,B) WT Arabidopsis seedlings (10 d old) were transferred to MS agar containing 1% (w/v) sucrose and 0 mM (–Pi) or 1.0 mM (+Pi) Pi and were grown for 10 d. (A) TAG content in shoots and roots of WT Arabidopsis plants. FW, fresh weight. (B) Electron microscopy of WT Arabidopsis leaves. White arrows, oil droplets; C, chloroplast; M, mitochondrion; S, starch. Bar = 0.5 μm. (C) Effect of Pi concentration on shoot TAG levels in WT Arabidopsis plants. WT Arabidopsis seedlings (10 d old) were transferred to MS agar containing 1% (w/v) sucrose and various concentrations of Pi and were grown for 10 d. DW, dry weight. (D) TAG levels in shoots of tomato (Solanum lycopersicum L.) plants grown for 8 d with 1 mM Pi followed by 28 d with (+) or without (–) Pi. (E) Tobacco (Nicotiana tabacum) plants grown for 10 d with Pi followed by 21 d with (+) or without (–) Pi. (F) Barnyard grass (Echinochloa crus-galli) plants grown for 8 d with Pi followed by 28 d with (+) or without (–) Pi. Data are the mean ± SD from three independent experiments.
