NTRC Is Involved in Lateral Root Formation in Arabidopsis Seedlings.

(A) Images of 11-d-old wild-type (WT) and ntrc mutant seedlings, as indicated, grown under long-day conditions.

(B) Quantification of the number of lateral roots related to root length of seedlings of the different Arabidopsis lines, as indicated, grown for 11 d under long-day conditions.

(C) Five-day-old wild-type and ntrc mutant seedlings grown on MS media were transferred to media supplemented with increasing concentrations of IAA for an additional period of 3 d. Root length was expressed as a percentage of root elongation of untreated seedlings, which was considered 100%. Assays were repeated three times with at least 21 plants per treatment. Mean values ± se are indicated.
