Root hair growth analysis in WT, <i>ahk2ahk3</i> and <i>ipt1,3,5,7</i> plants.

<p>Root hair length (A) and number of root hairs (B) in the seedlings were analyzed. The number of root hairs was counted in a 3 mm region from the starting point of the RHDZ. In order to measure root hair length, the longest root hairs (n = 8) per seedling (n>10) were chosen and measured. Different letters indicate significant differences from each other as determined using ANOVA (P<0.05) and significances were corrected post hoc using Tukey’s HSD comparisons.</p>
