Comparison of the effects of altered area-based photosynthesis and C partitioning coefficients on plant growth in Arabidopsis with altered CGR2 and CGR3 expression. Modeled effects on leaf area and leaf, root, and plant dry weights when either photosynthetic rates or partitioning coefficients spanning the entire growth cycle for Col-0 are replaced by those of (A) CGR2OX and (B) cgr2/3 are presented. In (A) and (B), blue lines represent modeled growth for Col-0, and red squares represent measured data points (mean ± sd) for Col-0 at 29, 49, 63, and 82 DAS. Gray lines represent modeled data for Col-0 when its area-based photosynthesis rates are replaced by that of either CGR2OX (A) or cgr2/3 (B). Orange lines represent modeled data for Col-0 when its partitioning coefficients (Table I) are replaced by that of either CGR2OX (A) or cgr2/3 (B) without making any changes to area-based photosynthesis rates of Col-0. In (A), asterisks represent measured data for CGR2OX at 63 and 82 DAS. In (B), the dotted line indicates the upper limit of measured data for cgr2/3.
