Altered N Status in LBD Overexpressors.

(A) Plant phenotype of the analyzed wild type, LBD37, LBD38, and LBD39 OXs (from left to right). Bar = 2 cm.

(B) NO₃⁻ content.

(C) Starch content.

(D) Maximal and selective nitrate reductase activity, NRA, and NR activation (i.e., Vsel/Vmax).

(E) Protein content.

(F) Amino acid contents.

Results are from shoots of the plants shown in (A). Wild type (black bars), LBD37 (white bars), LBD38 (light-gray bar), and LBD39 OXs (medium-gray bars) were grown in high light conditions (cf. Figure 3H). Results are the average ± sd from three independent lines each. For each sample (i.e., line), materials from five individual plants were combined.
