Expression of auxin marker genes in
lines are downregulated. Leaves from 4-week old soil grown wild-type Col-0 and max2 line plants were collected at indicated time points after P. syringae DC3000 infection and used to extract RNA to check the relative expression of auxin marker genes, AFB1
(A) and TIR1
(B). For this analysis, 3 plants/line and 3 leaves/plant were used. Results are based on a minimum of 3 independent experiments. Asterisks indicate significant differences, as determined by Student’s t-test (*P < 0.05; **P < 0.01; two-tailed t test).
