Amino acid and sugar content of oep16 triple mutant and wild-type seedlings. (A and B) Amino acid concentrations (nmolg FW, n=3–4 ±SD) in 6-day-old seedlings of the oep16 triple mutant (1/2/4, black bars) and wild type (white bars). Seedlings were grown on nylon filters in the absence (A) and presence of 1 μM ABA (B). Tryptophan and cysteine were not determined. (C) Glucose, fructose, sucrose, and starch concentrations (μmol/g FW, n=3–4, ±SD) in seedling tissue described in A and B. Significance analysis was performed by a Student’s t-test with P-values <0.05 (*); <0.01 (**); and <0.005 (***), respectively. For complete data sets see Supplementary Table S3 at JXB online.
