Infection of cowpea cells with cowpea mosaic virus (CPMV) is accompanied by the appearance of tubular structures containing virus-like particles which protrude from or penetrate the cell wall. Immunogold labelling of sections of infected cells using antisera against a CPMV M RNA translation products, and Protein A-gold, showed that the 58K and/or 48K tentative transport proteins of CPMV were located in or on these tubular structures. Furthermore, these proteins were detected in small electron-dense areas near the tail-end of the tubules. The possible function of these structures in virus movement from cell to cell is discussed.
