Comparison of Root Growth and Lateral Root Formation in Wild-Type and GH3 Mutants

GenotypeRoot Growth (mm/d)Lateral Roots (no./plant)
Col4.3 (0.1)4.9 (0.7)
gh3.5-14.4 (0.1)3.5 (0.5)
gh3.17-14.1 (0.1)4.5 (0.6)
Ler4.8 (0.1)4.0 (0.8)
gh3.1-14.7 (0.1)5.3 (0.7)
gh3.2-14.7 (0.2)4.8 (0.7)
  • Values are the means (±se) for seedling root growth rate over 3 d (n = 20) and number of lateral roots/seedling (n = 22). Col and Ler are the wild types for mutants with which they are grouped.
