	10.b17	AtHVA22a protein, ABA- and stress-inducible	U
	11.l15	Supersensitive to ABA and drought		D
	1.j9	Transcription factor, ABA and drought responsive	U	D
	8.p19	Abscisic stress ripening protein-like protein	U	U
Ethylene	15.h15	EIL2, ethylene transcriptional factor	D	D
JA	Contig 57	SAM:JA carboxyl methyltransferase	D	D
Cytokinin	10.j15	Proline dehydrogenase/oxygenase, cytokinin inducible	U

Cold refers to either of the two cold treatments: 3 d cold followed by 3 h or 24h refreshment, and dehydration to either of the two ambient dehydration treatments: 6 h or 48 h followed by a 3 h refreshment.

D, down-regulated; U, up-regulated. where no response is recorded, array values did not pass the statistical tests; for contigs, a change is noted if the signals from one or more of the probes from that contig on the arrays changed significantly and consistently.
