First report of lettuce mosaic virus infecting pea in Taiwan.
Pea (Pisum sativum) is the fourth largest leguminous vegetable in cultivated area in Taiwan. In 2016 and 2017, pea plants with unfamiliar symptoms of foliar vein banding and mottling were collected from Miaoli (ML) and Changhua (CH) counties. These symptomatic plants also had shortened internodes and malformed pea pods. The causal pathogen was isolated and identified as Lettuce mosaic virus (LMV) based on serological, molecular and pathogenicity analyses. This is thought to be the first report of LMV infecting pea in Taiwan.
