Chilli leaf curl Palampur virus is a distinct begomovirus species associated with a betasatellite
Plant Pathology, 2011 Capsicum frutescens (chilli) plants exhibiting leaf curl symptoms, collected from Palampur, Himachal Pradesh region of India, were found associated with a begomovirus and a betasatellite-like molecule. Viral DNA was amplified, cloned and sequenced. The

Functional analysis of a novel βV1 gene identified in a geminivirus betasatellite
Science China Life Sciences, 2020Betasatellites (DNA β) are circular ssDNA molecules that are associated with monopartite geminiviruses and exert a positive effect on the viral infection. Betasatellites encode one protein, named βC1, on the complementary strand; βC1 functions as a pathogenicity factor and RNA silencing suppressor.

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

Geminiviral betasatellites: critical viral ammunition to conquer plant immunity
Archives of Virology, 2023Geminiviruses have mastered plant cell modulation and immune invasion to ensue prolific infection. Encoding a relatively small number of multifunctional proteins, geminiviruses rely on satellites to efficiently re-wire plant immunity, thereby fostering virulence.

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

Role of betasatellite in the pathogenesis of a bipartite begomovirus affecting tomato in India
Archives of Virology, 2012Betasatellites 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.

Geminivirus-Associated Betasatellites: Exploiting Chinks in the Antiviral Arsenal of Plants
Trends in Plant Science, 2019Betasatellites 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.

Cotton Leaf Curl Multan Betasatellite as a Tool to Study the Localization of Geminiviruses in Plants
Molecular Biology, 2021Cotton 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, 2019Betasatellites 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.

Functional characterization of βC1 gene of Cotton leaf curl Multan betasatellite
Virus Genes, 2012Whitefly-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.
