Summary

Enzyme-linked immunosorbent assay (ELISA), used in conjunction with a new rapid extraction method, showed that potato leafroll virus (PLRV) concentration in the vascular region of infected potato tubers decreases from the heel to the rose end. Lower virus concentration at the rose than at the heel end was found not only in dormant tubers but also in tubers three weeks after breaking dormancy although the difference was then less pronounced. These results were obtained from plants with both primary and secondary infection by one of two French virus isolates which behave differently in respect of either accumulation in the ants or in their serological properties or both.
