First Report of a Begomovirus and Associated Betasatellite in Rosa indica and in India [PDF]

open access: yesAustralasian Plant Disease Notes, 2014
The complete genome sequences of a begomovirus and associated betasatellite was obtained by the rolling circle amplification from rose (Rosa indica) exhibiting dwarfing, leaf distortion and leaf curling symptoms from Rajasthan, India. The sequence of the begomovirus was determined to be 2,741 bp and showed the typical genome arrangement of an ...

Whitefly-mediated transmission of cotton leaf curl Multan betasatellite: evidence for betasatellite encapsidation in coat protein of helper begomoviruses

Archives of Virology, 2012
Cotton leaf curl Multan betasatellite (CLCuMB) is responsible for symptom expression of a devastating disease of cotton in the Indian subcontinent. CLCuMB depends on helper virus replication-associated protein for its replication and on viral coat protein (CP) for its encapsidation. However, no direct evidence of encapsidation of CLCuMB in viral CP has

Detection and characterization of a new betasatellite: variation in disease symptoms of tomato leaf curl Pakistan virus-India due to associated betasatellite

Archives of Virology, 2012
A begomovirus and its associated betasatellites were amplified and sequenced from tobacco plants affected with leaf curl disease. The begomovirus was identified as a new strain of tomato leaf curl Pakistan virus (ToLCPKV), which is referred to here as ToLCPKV-India. A previously known betasatellite [tomato leaf curl Patna betasatellite (ToLCPaB)] and a

Geminivirus-Associated Betasatellites: Exploiting Chinks in the Antiviral Arsenal of Plants

Trends in Plant Science, 2019
Betasatellites are a diverse group of circular single-stranded DNA satellites frequently associated with begomoviruses belonging to the family Geminiviridae. Challenged with a geminivirus-betasatellite infection, plants have employed sophisticated defense mechanisms to protect themselves.

Role of betasatellite in the pathogenesis of a bipartite begomovirus affecting tomato in India

Archives of Virology, 2012
Betasatellites are commonly associated with tomato leaf curl disease caused by begomoviruses in India. This study demonstrates the role of a betasatellite in the pathogenesis of tomato leaf curl New Delhi virus (ToLCNDV), a bipartite begomovirus affecting tomato in India.

Cotton Leaf Curl Multan Betasatellite as a Tool to Study the Localization of Geminiviruses in Plants

Molecular Biology, 2021
Cotton leaf curl Multan betasatellite (CLCuMB) is a ubiquitous betasatellite commonly found along with cotton leaf curl disease (CLCuD) associated begomoviruses in the Old World. It has a promiscuous replicative nature and trans-replicated by a diverse range of geminiviruses.

Journey of begomovirus betasatellite molecules: from satellites to indispensable partners

Virus Genes, 2019
Betasatellites are a group of circular, single-stranded DNA molecules that are frequently found to be associated with monopartite begomoviruses of the family Geminiviridae. Betasatellites require their helper viruses for replication, movement, and encapsidation and they are often essential for induction of typical disease symptoms.

Sesbania bispinosa, a new host of a begomovirus-betasatellite complex in Pakistan

Canadian Journal of Plant Pathology, 2016
AbstractSymptoms of severe leaf curling, yellowing and vein thickening, typical of begomovirus infection, were observed on Sesbania bispinosa grown in cotton leaf curl disease affected cotton fields in Pakistan. A begomovirus and its associated betasatellite were amplified and sequenced from these affected plants.

Functional characterization of βC1 gene of Cotton leaf curl Multan betasatellite

Virus Genes, 2012
Whitefly-transmitted Begomoviruses having circular single stranded DNA genome cause severe leaf curl diseases in the tropical and subtropical region. The majority of Old World monopartite begomoviruses with DNA A component is associated with a satellite DNA of 1.3 kb length referred to as betasatellites.

Characterization of a new begomovirus and betasatellite associated with chilli leaf curl disease in India

Archives of Virology, 2016
Chilli leaf curl disease (ChiLCD) is a serious problem and a major limitation to chilli (Capsicum spp.) cultivation in India. Leaves of a chilli plant showing leaf curl symptoms were collected from the Gonda district in Uttar Pradesh, India, in April, 2013.
