ukl1 and ukl2 Show Reduced Sensitivity to 5-FU and 5-FD Inhibition of Seedling Growth.

(A) ukl1 and ukl2 are more tolerant to 5-FU and 5-FD inhibition of seedling growth. The wild type and mutants were germinated on half-strength MS medium supplemented with 5-FU or 5-FD at specified concentrations for 5 d. Col, Columbia ecotype.

(B) Quantification of the chlorophyll content of the wild type and mutants grown on MS medium containing different concentrations of 5-FU or 5-FD for 5 d. Data are expressed as mean ± se for three measurements. FW, fresh weight.
