Percentage of Wild-Type and dmi2-1 Root Hairs Showing Has and RHD in Hairs That Were Growing at the Time of Rough NF Application.

Forty-five minutes after application, there is already a clear difference between the wild type and dmi2-1. A significant higher percentage dmi2-1 root hairs shows swelling of the root hair tip. At 180 min after application, 59% of the dmi2-1 root hairs, which were growing at the time of NF application (but became growth terminating because of the medium change), show NF-induced RHD. In the wild type, only 12% of the root hairs, which were growing at the time of NF application, show NF-induced RHD. Monitored were six roots for the wild type and dmi2-1, respectively, >50 root hairs per root.
