Figure 4. Mutations in IAR4 confer resistance to isoxaben.

Figure 4

(A) Root phenotypes of indicated seedlings germinated and grown for five days on MS medium with 0% sucrose and then transferred for 48 hours to MS medium with 0% sucrose containing either 0 nM (DMSO), 1 nM or 2 nM isoxaben. Representative root tips were imaged using dark field microscopy. Scale bar = 0.5 mm. (B) Quantification of the root tip swelling from (A). The width of the roots was measured at the level of the youngest root hair using ImageJ software [48]. Values are the means (n>8) ± SE. Data were analyzed by unpaired Student's t-test. Asterisks indicate significant differences relative to the wild type; P<0.05.
