Root growth analysis shows that rsw1-1 partially complements any1, and any1 complements the radial swelling of rsw1-1 in transheterozygotes. A, Wild type, any1, rsw1-1, and transheterozygotes (any1/rsw1-1) were grown for 5 d at 21°C, then moved to 29°C. Black dots indicate the location of the root tip when the plants were moved to 29°C. B, Images of roots grown for 6 d at 21°C and for 5 d at 21°C and 1 d at 29°C. The distance between the white line and the root tip show the root growth for 1 d at either 21°C or 29°C. Scale bars = 1 mm. C, Root elongation rates showing that transheterozygote (TH) has an elongation rate intermediate between wild type and any1. Values are means ± sd (n = 20). D, Root diameter of rsw1-1 increases when plants are grown at 29°C, while transheterozygotes have similar root thickness to any1 at both 21°C and 29°C. Values are means ± sd (n = 20). Asterisks show significant differences (P < 0.0001). *1, Significant difference between any1 and wild type, TH and rsw1-1; *2, Significant difference between rsw1-1 and wild type, any1 and TH; *3, Significant difference between any1 and wild type and rsw1-1.
