The subject application provides polynucleotides, compositions thereof and methods for regulating gene expression in a plant. Polynucleotides disclosed herein comprise novel sequences for a promoter isolated from Panicum virgatum (switchgrass) that initiates transcription of an operably linked nucleotide sequence. Thus, various embodiments of the invention comprise the nucleotide sequence of SEQ ID NO: 2 or fragments thereof comprising nucleotides 1 to 692 of SEQ ID NO: 2 that are capable of driving the expression of an operably linked nucleic acid sequence.
This invention was made with United States Government support under Department of Energy Bioenergy Science Center IP Management Plan Agreement contract number DE-AC05-00OR22725. Subcontract No. UT-4000063906. The United States Government has certain rights in the invention.
