Role of G protein subunits in sensing sugar in RSA maintenance. (A) Primary root length of 11-day-old seedlings of Gα, Gβ and Gαβ double subunit mutants (indicated genotypes) were grown on ½ X MS, and 0.75% agar, 22°C, 8:16 light: dark cycle for 4 days followed by 7 days of vertical growth on different concentrations of glucose. (B) Lateral root number (C) Lateral root density. All experiments were repeated 3 times with 10–15 seedlings of each genotype per trial. Error bars represent standard error Student’s t-test results are based on difference between the wild type and indicated genotype shown as asterisks:^∗P < 0.05.
