Nuclear position (A) and root hair growth rate (B) in growing M. truncatula root hairs after control treatment and treatment with 1 μm oryzalin or 1 μm taxol. In controls and taxol-treated hairs, the nucleus kept a distance of 30 to 40 μm to the tip over time, but it was significantly increased in oryzalin (A). Growth rate in the hairs remained high in controls, but dropped by approximately 60% in oryzalin and taxol (B). Results for each treatment are presented as the means of 10 hairs with their sd. Results are representative for three independent replicates for each treatment.
