The barley gene (Jip23) encoding a 23,000-Da protein of unknown function was isolated and shown to be induced by jasmonate methyl ester (MeJA) in leaves. 5'upstream Jip23 sequence was isolated and fused to the beta-glucuronidase gene (GUS), and this reporter was introduced by particle bombardment into barley leaves. With 1.

They are suggested to play a role in the cis unfolding and folding of the chromatin fibre associated with the regulation of gene transcription. Inclusion of MARs in transgene cassettes enhances their expression and reduces position-effect variations in the transgenic host.
