Results are shown as mean ± SD for 3–6 replicates, with each replicate being shoots from 7 to 12 plants grown in one hydroponics container. ∗Indicates significance (p < 0.05) in two-way ANOVA multiple comparisons test. Comparison was made to control A-lines grown on either Pi or IHP. Numbers in parentheses indicate fold change over the average of three control A-lines.
