Abstract

We have previously demonstrated that African cassava mosaic virus (ACMV) DNAs A and B efficiently complement the systemic spread of tomato golden mosaic virus (TGMV) DNA A when co-agroinoculated onto . Here, we show that a mixture of an ACMV DNA A mutant and DNA B that is normally unable to systemically infect can do so at low frequency when co-agroinoculated with TGMV DNA A. Analysis of viral DNA showed that the mutation was retained during infection. The mixture of genomic components was sap transmissible, indicating that systemic infectivity is not specifically attributable to the use of agroinoculation. In the presence of TGMV DNA A, ACMV coat protein as well as the DNA B gene products BV1 and BC1 were detected in systemically infected tissues. The results demonstrate that dysfunctional can be complemented by its TGMV homologue .
