Expression data from WT (Columbia) and pifq (pif1pif3pif4pif5) mutant Arabidopsis seedlings

ABSTRACT: Plants respond to changes in the red:far red ratio (R:FR) of incident light. A reduction in this ratio (increase in FR) results in the Shade Avoidance Response (SAR) with associated changes in gene expression. The Phyotchrome-Interacting Factors (PIFs) are bHLH transcription factors known to be involved in the SAR. An analysis of changes in gene expression in WT and quadruple pif1pif3pif4pif5 (pifq; Leivar et al., 2008 (PMID 19920208)) mutant seedlings in response to an increase in FR should identify primary targets of PIF signaling. We used microarrays to examine the SAR in WT (Columbia) and pifq mutant Arabidopsis seedlings. Arabidopsis WT and pifq mutant seeds were plated on GM medium without sucrose at room temperature. During this procedure, the seeds were routinely exposed to white
