Relationship between type of core promoter and gene function

Abstract

Core promoter locates from -50 to +50 relative to the major transcription start site (TSS) in a promoter. It is recognized by the pre-initiation complex and determines direction and position of transcriptional initiation. We have collected large amount of TSS tags from Arabidopsis, and in combination with statistical analyses of promoter sequences, we have discovered novel plant-specific core promoter elements. Based on these findings, we further investigated relationship of the core promoter type to gene category and gene structure.
