First record of Turnip mosaic virus in Cook’s scurvy grass (Lepidium oleraceum agg.) — an endangered native plant in New Zealand

Abstract

Cook’s scurvy grass (Lepidium oleraceum agg.) is an endangered species of native Brassicaceae that is considered threatened with extinction. Virus-like disease symptoms were observed in a newly introduced plant of L. oleraceum at Stony Bay, Banks Peninsula, Canterbury, New Zealand. This is the first record of a virus in L. oleraceum and the first report of a Turnip mosaic virus infection in a New Zealand native host.
