Abstract

Turnip mosaic virus (TuMV) was reported in New Zealand for the first time in 1936. Until recently, TuMV had been found in nine hosts in this country. Using transmission electron microscopy, mechanical inoculation of herbaceous indicators, and molecular and serological techniques as detection and identification methods, another five new plant host records are reported from plants collected during surveillance and in post-entry quarantine. The new plant hosts infected with TuMV in New Zealand are Crocus sativus (Saffron), Erodium moschatum (Musky storkbill), Lobelia speciosa (Lobelia), Nasturtium officinale (Watercress) and Tropaelum majus (Nasturtium). The sequence analysis of the amplicons of TuMV indicates that the virus exists in a population of variants in New Zealand.
