ABSTRACT

Northern cereal mosaic cytorhabdovirus (NCMV) and Barley yellow striate mosaic cytorhabdovirus (BYSMV) are two of the most important viral pathogens of wheat. Northern China is the main wheatproducing region in the country. Wheat growing regions pertaining to four provinces, located in northern China, were surveyed for occurrence of NCMV and BYSMV during the growing seasons of the years 2010 and 2016. Wheat leaf samples were collected randomly from symptomatic plants displaying stunting, chlorotic stripes or mosaic. Roughly 73 samples were collected in the year 2010 from 13 fields, and 154 samples were collected in 2016 from 41 fields. Samples were tested for the presence of NCMV or BYSMV using multiplex reverse transcription-polymerase chain reaction (mRTPCR). The results suggested that BYSMV (49.32% in 2010, 82.47% in 2016) is gradually replacing NCMV (87.67% in 2010, 13.64% in 2016) and becoming the main cytorhabdovirus in different wheat growing regions in northern China.


O cytorhabdovirus do mosaico do cereal do norte (NCMV) e o cytorhabdovirus do mosaico estriado amarelo da cevada (BYSMV) são dois dos mais importantes patógenos virais do trigo. O norte da China é a principal região produtora de trigo do país. As regiões produtoras de trigo pertencentes a quatro províncias do norte da China foram pesquisadas quanto à ocorrência de NCMV e BYSMV durante as safras dos anos de 2010 e 2016. Amostras de folhas de trigo foram coletadas aleatoriamente de plantas sintomáticas, exibindo listras ou mosaico clorótico com baixo crescimento. Cerca de 73 amostras foram coletadas no ano de 2010 a partir de 13 campos, e 154 amostras foram coletadas em 2016 de 41 campos. As amostras foram testadas quanto à presença de NCMV ou BYSMV usando reação em cadeia da polimerase de transcrição reversa multiplex (mRT-PCR). Os resultados sugerem que o BYSMV (49,32% em 2010, 82,47% em 2016) está gradualmente substituindo o NCMV (87,67% em 2010, 13,64% em 2016) e se tornando o principal cytorhabdovirus em diferentes regiões produtoras de trigo no norte da China.
