E-GEOD-45728 - Expression data from low R:FR - SA crosstalk in Arabidopsis
Released on 3 April 2013, last updated on 8 December 2015
Low R:FR signaling through phytochromes induces shade avoidance responses, including petiole elongation. Salicylic acid-mediated defense against pathogens is inhibited under these conditions. Using microarrays we studied the crosstalk between low R:FR and SA at the global gene expression level in Arabidopsis thaliana. Plants were exposed for 2 h. to the following treatments: high R/FR with mock spray, low R/FR with mock spray, high R/FR with SA spray, low R/FR with SA spray. Gene expression was determined in petioles.
