Progress on the effect of 5'UTR on gene expression and regulation in plants
Plant 5'untranslated region(UTR)involves a variety of regulatory elements,such as internal ribo-somal entry site,upstream open reading frame,introns,and various secondary structures,which play im-portant roles in gene expression and regulation.5'UTR can also produce multiple mRNA variants by re-taining,deletion or mutation of regulatory elements to modulate translation efficiency.In this review,we summarize various regulatory elements and secondary structures involved in plant 5'UTR sequence,and expect to provide a comprehensive understanding of the structures and functions of plant 5'UTR,which may provide the evidence for further study in relevant field.
