TABLE 1.

GALT activity and the amount of β-Yariv-precipitated AGPs in wild type and galt2 mutant plants

Detergent-solubilized microsomal fractions were used for performing a standard GALT assay, and AGPs were extracted, precipitated by β-Yariv reagent, and quantified from 14-day-old plants. The values are the averages of at least two experiments from two biological replicates. The S.E. values are indicated.

Genetic line	GALT activity	β-Yariv-precipitated AGPs
	pmol/h/mg	μg/g
Wild type	6.7 ± 0.8	14.1 ± 3.5
galt2-1	5.3 ± 1.2	9.6 ± 3.5
galt2-2	5.8 ± 1.0	9.2 ± 2.8
