Differential Expression of Auxin- and Cell Wall-Related Genes in Root Segments.

(A) Word cloud from annotations of genes differentially expressed between Bd21-0 versus tar2l^hypo, or mock-treated versus l-kynurenine-treated Bd21-0.

(B) to (G) Expression changes (fold changes) for individual members of the indicated gene classes in Bd21-0 versus tar2l^hypo and mock-treated versus l-kynurenine-treated Bd21-0 (Bd21-0/mock set to 1 on the left, tar2l^hypo/l-kynurenine-treated Bd21-0 values on the right). Only genes that showed differential expression and a q value < 0.01 in at least one comparison are plotted. See Supplemental Data Set 5 for gene identifiers and expression values.

(H) qPCR verification of differential gene expression in independent RNA samples prepared from independent root segments (three biological replicates). Error bars indicate se of the mean. Differences were not statistically significant (Student’s t test) unless indicated as follows: *P < 0.05, **P < 0.01, and ***P < 0.001.
