Analysis of NUE in AAP1-OE1 and wild-type (WT) plants grown with low (2 g of N per week), moderate (4 g of N per week), or high N (8 g of N per week) supply. NUE is determined by plant seed yield relative to the amount of N applied and is generally composed of both NUpE and NUtE (see “Materials and Methods”). A, Plant NUpE (n ≥ 5). B, Plant NUtE (n ≥ 5). C, Seed yield per plant (n ≥ 5). D, Plant NUE (n ≥ 5). Data are means ± sd. Significant differences are indicated by letters (ANOVA; P ≤ 0.05). Numbers above the columns indicate percentage changes between AAP1-OE and wild-type plants grown under the same (solid brackets) or different (dashed brackets) N conditions.
