Expression data from seedlings of two light grown Arabidopsis thaliana CSN mutants and two wild type ecotypes

The COP9 signalosome (CSN) is a highly conserved complex consisting of eight subunits, which influences key developmental pathways through its regulation of protein stability and transcription. Mutations in each of the CSN subunits exhibits diverse pleiotropic phenotypes We used microarrays to compare gene expression of two CSN mutants with their corresponding wild types: a non-lethal csn5a-1 mutant, vs. columbia ecotype, and a lethal, csn8 mutant, vs. Wassilewskija ecotype Light grown seedlings of the two wild types and two mutants were selected for RNA extraction and hybridization on Affymetrix microarrays
