Table 1. Quality control of microarray experiments.

Pathway	AGI	Gene Name	Microarray FC	qRT-PCR FC
ethylene	At4g08040	ACS11	3.4	4.4
ABA	At3g14440	NCED3	3.8	3.6
auxin	At2g23170	GH3.3	19.2	28.6
auxin	At1g15580	IAA5	7.8	10.2
auxin	At4g14560	IAA1	6.2	9.3

The fold change (FC) of genes that were differentially expressed during the microarray analysis after dicamba treatment were confirmed by qRT-PCR. Each qRT-PCR experiment was done twice with the average of the fold change reported.
