The Arabidopsis thaliana polyubiquitin 10 (Ubi10; UBQ10)
regulatory sequence is comprised of the promoter, 5' untranslated
region and intron. The ubiquitin 10 promoter is a constitutive
promoter that promotes high-levels of transcription in plant
systems. The promoter is not tissue specific and high levels of
transcription would be expected in all plant tissues.
