First report of Turnip yellows virus in cabbage in the Philippines

Abstract

Brassica oleracea var. capitata) showing leaf yellowing symptoms In March 2017, 52 dried-leaf samples of brassicaceous plants from the Philippine Highlands, one of which was a sample of cabbage (Brassica oleracea var. capitata; Fig. 1), were submitted to Fera Science Ltd., via the Centre for Agriculture and Bioscience International (CABI). The plants were all displaying virus-like, yellowing symptoms (Reeder et al., 2017).Initially, samples were bulked together and tested by ELISA for the presence of viruses known to occur in the Brassicaceae includingThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Comparisons between sequenced and re-sequenced genomes of historical subterranean clover mottle virus isolates

“…Finally, although not identified during the de novo assembly and mapping of the HTS reads of the five historical SCMoV isolates against previously identified satellites (Davies et al 1990), BWA (Li and Durbin 2009) and SAMtools ) revealed single satellite RNAs associated with each isolate (satellite accession numbers OM818397-OM818401) with between 96.4-98.2% nt identities to SCMoV satellite with accession number M33001.1 (Davies et al 1990). Presence of a turnip yellows virus (TuYV) sequence within samples containing isolates AL, MB and NN was confirmed by real time PCR (Buxton-Kirk et al 2021). By contrast, SS did not identify satellite RNA or TuYV within any samples presumably because SS employs virus-specific or group-specific degenerate primers, whereas HTS can potentially sequence any RNA present in a sample.…”

First report of Snowdrop virus Y and Turnip yellows virus in Narcissus sp. in the United Kingdom

“…TuYV was confirmed by real‐time RT‐PCR (Buxton‐Kirk et al., 2021). This is the first host record of TuYV in Narcissus .…”

Discovery of Brassica Yellows Virus and Porcine Reproductive and Respiratory Syndrome Virus in Diaphorina citri and Changes in Virome Due to Infection with ‘ Ca . L. asiaticus’

“…BrYV was first identified in China in 2011 ( 10 ) and is tentatively placed in the genus Polerovirus (Solemoviridae); it has since been reported in Korea ( 11 ), Japan ( 13 ) and Australia ( 14 ). Molecular and phylogenetic studies show BrYV is closely related to turnip yellows virus (TuYV: Luteoviridae) ( 10 , 14 , 15 ), which has been reported throughout Europe, South Africa, China, Iran, Egypt, South Africa, Egypt, Morocco, and Australia, and infects crops and weeds, including members of the Brassicaceae, Fabaceae, Amaranthaceae and Asteraceae (see references in [14]). Poleroviruses are mostly transmitted by aphids in a circulative and nonreplicative mode ( 16 – 19 ); one known polerovirus is transmitted by whiteflies, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) ( 20 ).…”
