Abstract: "[Investigators] performed in vivo isotopic labeling of Arabidopsis thaliana rosettes with (13)CO2 and estimated fluxes throughout leaf photosynthetic metabolism by INST-MFA [Isotopically nonstationary metabolic flux analysis]. Plants grown at 200 µmol m^(-2)s^(-1) light were compared with plants acclimated for 9 d at an irradiance of 500 µmol⋅m^(-2)⋅s^(-1)." |

P.16970 left column 5th paragraph: "Despite the increase in photorespiration, the relative flux to sucrose export also increased to support more biomass production in HL-ACC [high light acclimated] plants. Sucrose export flux more than doubled from 11.7 to 26.4 µmol (hexose units)/gFW/hr, whereas starch production increased marginally from 6.3 to 8.5 µmol (hexose units)/gFW/hr. Higher carryover starch levels were observed in HL-ACC leaves throughout the diurnal cycle (Fig. S1). HL-ACC plants also had elevated levels of RuBisCO on the basis of leaf area, FW, or chlorophyll and produced thicker leaves with more biomass (Fig. S1). Furthermore, HL-ACC plants produced more seed biomass (i.e., 10 plants produced approximately twice the amount of seeds that resulted in 93% more biomass by weight) with a greater amount of oil, had altered leaf chlorophyll levels (Fig. S1), and had reduced measured concentrations of several of the Calvin cycle intermediates (Table S1)." |
