title: Gene I products of cauliflower mosaic virus detected in extracts of infected tissue.
abstract: The product of cauliflower mosaic virus (CaMV) gene I has been characterized from extracts of infected plants. Two size classes of this protein can be identified by the use of specific antiserum. The antiserum was induced against a chimeric protein produced in E. coli from a gene fusion between a fragment of the CaMV genome and the beta-galactosidase gene. A 36-kDa form of the gene I product is associated with virus particles. A 45-kDa form of this product was found only in the insoluble fraction of tissue homogenates. This insoluble fraction, the only fraction found to contain the product of viral gene VI, contains the virally induced inclusion bodies.
