Figure S2. Complementation analyses of sng2-2 mutant seeds. The sng2-2 mutant was complemented with the construct overexpressing SCT under CsMV promoter. Total GSL profiles at 229 nm (a) and SnGSL profiles at 330 nm (b) are extracted from the same diode array dataset and the y-axis of each chromatogram is scaled equivalently.
