Activities of galactinol synthase, raffinose synthase, and stachyose synthase in yellowing seeds of three soybean lines

Line	Galactinol Synthase	Raffinose Synthase	Stachyose Synthase
A1923	7.5 ± 4.1	0.10 ± 0.05	0.65 ± 0.18
LR28	16.5 ± 5.2	0.004 ± 0.007	0.81 ± 0.24
LR33xLR28	22.6 ± 8.8	0.006 ± 0.008	0.87 ± 0.21

The wild-type control is line A1923. Enzyme activities are expressed as μmol of product produced per gram fresh wt per hour under the assay conditions. Values are mean ± sd for five replicates.
