Heterogeneity in the 3'-terminal untranslated region of tobacco mild green mosaic tobamoviruses from Nicotiana glauca resulting in variants with three or six pseudoknots.

Abstract excerpt

Isolates of tobacco mild green mosaic tobamovirus (TMGMV) were obtained from 58 plants of Nicotiana glauca in southern California and placed in one of two groups (Small type and Large type) based on the size of the subgenomic RNA for the coat protein (CP). The CP sequence differed by no more than one amino acid for the two types, and the Small type was identical to that published for TMGMV. Thirty-six of the...
