Analysis of the B₆ vitamer contents in the different plant lines. A, Analysis of the individual B₆ vitamers PMP, PLP, PM, PN, and PL profile of the lines as indicated. B, Total vitamer contents (sum of PMP, PLP, PM, PN, and PL). Plants were grown at high CO₂ (2,000 ppm) for 33 d to avoid pleiotropic effects on B₆ vitamers in dwarf type er-ant1 plants. Data represent the mean of four replicates per line that was used for two extractions each. SEs are given. Statistical relevance was determined by a Student’s t test using the wt of the respective growth condition as a reference: ^*P ≤ 0.05, ^**P ≤ 0.005, and ^***P ≤ 0.0005.
