Gene expression profiling data contains more information than is routinely extracted with standard approaches. Here we present Fold-Change-Specific Enrichment Analysis (FSEA), a new method for functional annotation of differentially expressed genes from transcriptome data with respect to their fold changes. FSEA identifies Gene Ontology (GO) terms, which are shared by the group of genes with a similar magnitude of response, and assesses these changes.
View Article and Find Full Text PDFAuxin is the major regulator of plant growth and development. It regulates gene expression via a family of transcription factors (ARFs) that bind to auxin responsive elements (AuxREs) in the gene promoters. The canonical AuxREs found in regulatory regions of many auxin responsive genes contain the TGTCTC core motif, whereas ARF binding site is a degenerate TGTCNN with TGTCGG strongly preferred.
