The 5′-terminal sequence of TMV RNA question on the polymorphism found invulgarestrain

Abstract
The complete nucleotide sequence of TMV RNA (common strain) reported in [Proc. Natl. Acad. Sci. USA (1982) 79, 5818] its 5′-end to be represented by two variants which differed in length. We have tested that result and sequenced the 5′-terminal regions of two strains of TMV RNA (common strain OM and tomato strain L) using cloned cDNA copies. The results showed that the 5′-terminal region of the TMV genome is not polymorphic and that one of the two variants cited above represents a tomato strain but not the common strain.
