Abstract
In reticulocyte lysates maize rayado fino virus RNA directed the synthesis of a large number of polypeptides ranging in Mr from 15000 to 165000. Partial proteolysis showed that many of the larger polypeptides contained the same peptides. When tRNA was added to the lysate proportionally more of the large Mr products were produced. No polypeptides were detected that comigrated with coat proteins and no coat protein was detected in translation products by ELISA or by immunoprecipitation. We found little evidence of polyprotein degradation among the translation products and no evidence for encapsidated subgenomic mRNAs for the capsid polypeptides.
