The Citrus tristeza virus replication signal is a
regulatory element
A regulatory sequence is a segment of a nucleic acid molecule which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and vir ...

replication signal which is highly conserved in citrus tristeza viruses. Replication signals are required for viral replication and are usually found near the 5' and 3' termini of
protein coding genes. This element is predicted to form ten stem loop structures some of which are essential for functions that provide for efficient viral replication.
