Figure 1. Loss of SDG2 reduces both primary and lateral root growth. A,

Phenotypes of wild-type Col and the mutant sdg2-3 seedlings at 26 days after germination. Bar = 1 cm. B, Comparison of primary root length between Col and sdg2-3 from 4 to 18 days after germination. C, Comparison of lateral root number between Col and sdg2-3 from 8 to 18 days after germination. All data are mean values from two independent experiments with each of at least 20 plants. Bars indicate SD.
