Figure 1From: Switchgrass (Panicum virgatum L.) polyubiquitin gene (PvUbi1 and PvUbi2) promoters for use in plant transformationMap of the PvUbi1 and PvUbi2 genes within the contiguous 10.4 kb sequence of switchgrass DNA in Pv9G7B5. The light gray boxes represent the 228 bp ubiquitin monomer repeats of the translated exon. The black boxes represent the non-coding exons downstream of each TATA box for PvUbi1 and PvUbi2. The intron splices sites (CAAG/gta and cag/ATG) are shown.Back to article page
