Complete genome sequence of an isolate of Clerodendron yellow mosaic virus – a new begomovirus from India

Abstract

Summary. -Clerodendron inerme, a common hedge plant grown in India, is affected by a yellow mosaic disease caused by a begomovirus. In the present study, the complete genome (DNA A) of this virus was cloned and sequenced.

Detection and molecular characterization of Clerodendron yellow mosaic virus infecting Volkameria inermis in Pakistan

“…This suggests that ClYMV has a very narrow host range. In common with earlier reports, ClYMV does not appear to associate with either betasatellites or alphasatellites (Anwar et al 2012;Sivalingam et al 2011). V. inermis plants are propagated vegetatively from plant shoots/cuttings which provides a likely mechanism of spread of the virus in addition to insect transmission.…”

“…Additionally virus was detected in all six samples by Southern blotting using a V2 gene probe amplified with specific primer pair ClYMV-FP(GTGTGAATATTGGT TGCATCATGTGGG)/ClYMV-RP(ACCCAGGCCTGTCT TCTTGTGACG). ClYMV has been reported to infect V. inermis in India (Sivalingam et al 2011) and is an infrequently encountered begomovirus with only three other sequences available in the databases. This suggests that ClYMV has a very narrow host range.…”

First report of Clerondendron yellow mosaic virus on golden dewdrop (Duranta erecta) in India

“…2) Begomoviruses are associated with leaf curl disease in D. erecta (Iram et al, 2004); Catharanthus yellow mosaic virus in D. repens (Mustujab et al, 2015) and Tomato leaf curl New Delhi virus in D. repens (Tahir et al, 2006) from Pakistan. ClYMV has been reported on B. peruviana (Nehra et al, 2014) and C. inerme (Sivalingam et al, 2011) in India, but to the best of our knowledge this is the first report of natural occurrence of ClYMV on D. erecta in India.…”
