Auxin response of AuxRE-containing TMV-altered genes

AFGC gene model IDa	Protein nameb	No. of AuxREc	Fold expression in TMV infectiond	Fold expression after 50 μM IAA treatmente
At5g02160	Putative protein	3	−1.9	−4.1 ± 1.7
At1g19350	Unknown protein	3	−2.0	−1.8 ± 1.1
At3g17790	Acid phosphatase type 5	2	−2.3	−6.6 ± 4.0
At5g21010	Putative stress protein	3	−3.5	−1.5 ± 1.2
At4g38850	SAUR-AC1	1	−1.1f	5.1 ± 2.1

^aAFGC, Stanford University's Arabidopsis Functional Genomics Consortium; ID, identification.

^bGene functions based on sequence homologies.

^cNumber of TGTCTC and GAGACA sequences within 2 kb upstream of the start codon.

^dcDNA microarray fold expression values averaged from three independent biological replicates of TMV-infected tissues. Fold changes at or above 1.6 and at or below −1.9 occur above the 95% confidence interval used to identify transcriptionally altered genes (23).

^eQRT-PCR fold expression values and standard errors averaged from four independent auxin leaf treatments. Data were normalized against the expression levels of EF1α.

^fMicroarray fold changes for SAUR-AC1 were not above the 95% confidence interval cutoff in TMV-infected tissues.
