GL Measurements in the apk1 apk2 Double Knockout.

Comparison of levels of sulfated GLs in Col-0 and apk1 apk2 in rosette leaves (A) and seeds (B). Levels of total, aliphatic, and indolic GLs (left graph) are presented along with the levels of individual aliphatic (middle graph) and indolic GLs (right graph). 3MSOP, 3-methylsulfinylpropyl-GL; 4MSOB, 4-methylsulfinylbutyl-GL; 5MSOP, 5-methylsulfinylpentyl-GL; 7MSOH, 7-methylsulfinylheptyl-GL; 4MTB, 4-methylthiobutyl-GL; 8MSOO, 8-methylsulfinyloctyl-GL; 3OHP, 3-hydroxypropyl-GL; 4OHB, 4-hydroxybutyl-GL; 3BZO, 3-benzoyloxypropyl-GL; 4BZO, 4-benzoyloxybutyl-GL; 7MTH, 7-methylthioheptyl-GL; 8MTO, 8-methylthiooctyl-GL; 4OHI3M, 4-hydroxy-indolyl-3-methyl-GL; 1MOI3M, 1-methoxyindol-3-ylmethyl-GL. Data are presented as mean ± sd for five replicates (A) and eight replicates (B). Student's t test significantly different to the wild type at * P < 0.05, ** P < 0.01, and *** P < 0.001. n.d., not detected.
