E-GEOD-43819 - Expression data from WT, sid2-1
Released on 30 June 2013, last updated on 11 December 2015
Salicylic acid (SA) levels increase in Arabidopsis upon exposure to low temperature for more than a week. This cold-induced SA biosynthesis was found to proceed through the isochorismate synthase (ICS) pathway. The sid2-1 mutant is deficient in ICS1 and does not make SA at low temperature. We used microarray analysis to examine the genes differentially regulated by low temperature that were dependent on SA We used the sid2-1 mutant and a WT control at 22⁰C and after 3 weeks at 4⁰C. All samples were in triplicate.
