First Report of Turnip mosaic virus in Pisum sativum in Spain

During 2001 and 2002, Pisum sativum var. vulgare plants grown as commercial crops in Almeria (southeast Spain) showed vein clearing and chlorotic mottle of leaves, leaf deformation, flower abortion, necrotic mottle and deformation of pods, and stunted plant growth. Crude sap of collected plants was...

Zusammenfassung:During 2001 and 2002, Pisum sativum var. vulgare plants grown as commercial crops in Almeria (southeast Spain) showed vein clearing and chlorotic mottle of leaves, leaf deformation, flower abortion, necrotic mottle and deformation of pods, and stunted plant growth. Crude sap of collected plants was mechanically inoculated on healthy pea plants which reproduced symptoms observed in the field; local necrotic lesions were produced on mechanically infected Chenopodium quinoa, C. amaranticolor, and Gomphrena globosa, systemic mosaic symptoms on Brassica napus and Nicotiana benthamiana, and local lesions plus systemic mosaic symptoms on N. clevelandii, which are all characteristic of Turnip mosaic virus (TuMV) (1). A reverse transcription-polymerase chain reaction assay using general primers for the extreme 3' end of the potyvirus genome amplified products of 750 and 1,700 bp in nucleic acid extracts from naturally infected pea plants as well as from the mechanically infected test plants. The overlapping nucleotide sequences of the products (GenBank Accession No. AJ489259) had a nucleotide sequence identity of 86.5% and a derived amino acid identity of 95.0% with several published sequences of TuMV (1). This report cites the first partial nucleotide sequence of TuMV infecting pea crops, and although natural infections of this virus in pea have been reported in Morocco (1976) and in the United States (2), to our knowledge, this is the first report of TuMV in Spain.
