Parthenium hysterophorus plants exhibiting severe leaf curl and stunting symptoms were observed near agriculture fields in Lucknow, India. The association of a begomovirus, β-satellite, and α-satellite with these symptoms of a Parthenium disease was investigated by sequence analyses of virus and satellite DNA amplified by rolling circle amplification and polymerase chain reaction. The highest sequence identities and closest phylogenetic relationships for the begomovirus, β-satellite, and… 
Association of an isolate of papaya leaf curl virus and papaya leaf curl betasatellite with leaf curl disease of radish in India
Radish (Raphanus sativus L.) plants of the cultivar Pusa Reshmi exhibiting severe leaf curl symptoms were observed in the cultivated fields at Lucknow with significant disease incidence and the associated betas satellite was identified as papaya leaf curl betasatellite (PaLCuB) based on its highest sequence identity and close relationship with PaLCuV.

Total 163 sunflower plants samples showing leaf curling, phyllody and mixed infections of both were collected from different regions of Kurnool district of Andhra Pradesh state in India. The total
Identifying Genetic Diversity of Cotton Leaf Curl Virus in Commercial Cotton (Gossypium hirsutum L.)
Plant viruses have become a major issue to the crop production around the world. These viruses have become an unavoidable limiting factor by causing rigorous crop deficit for those major crops which
Begomoviruses and Their Satellites Occurring in India: Distribution, Diversity and Pathogenesis
In this chapter, research work on identification and characterization of begomoviruses in diverse crops in India is presented and Geographic distribution, phylogenetic relationship, infectivities of cloned genome components, recombination, replication events, suppression of RNAi silencing, viral gene funtions as pathogenicity determinants and association of satellites and their role in disease development with reference to the Indian begomviruses are discussed.
Identification and Analysis of Potential Genes Regulated by an Alphasatellite (TYLCCNA) that Contribute to Host Resistance against Tomato Yellow Leaf Curl China Virus and Its Betasatellite (TYLCCNV/TYLCCNB) Infection in Nicotiana benthamiana
The transcriptome profiles of Nicotiana benthamiana seedlings challenged by TYLCCNV/TYLCCNB or TYL CCNV/TyLCC NB or TY lCCNA are analyzed, suggesting that TYlCCNA responsive DEGs may attenuate TyLCC NV/TYlCCNB infection.

Parthenium hysterophorus, an emergent weedy plant species expands its geographical ranges in Pakistan
Parthenium hysterophorus [commonly known as Carrot grass; native to American tropics; family Asteraceae] is a flowering, short-lived perennial or an annual invasive-weedy plant. In the recent few


Tomato leaf curl virus from Bangalore (ToLCV-Ban4): sequence comparison with Indian ToLCV isolates, detection in plants and insects, and vector relationships}
Tomato leaf curl virus is a whitefly transmitted geminivirus causing a destructive disease of tomato in many regions of India, East Asia and Australia, andPhylogenetic analysis showed that the ToLCV isolates from Bangalore constitute a group of viruses separated from those of Northern India.
A Geminivirus-Satellite Complex is Associated with Leaf Deformity of Mentha (Mint) Plants in Punjab
The evidence indicates the association of ToLCKV and CLCuMB, a hitherto new combination of a begomovirus and a betasatellite associated with a leaf deformity disease in mentha in Punjab.
Tomato leaf curl Karnataka virus from Bangalore, India, Appears to be a Recombinant Begomovirus.
This ToLCV is a distinct member of the genus Begomovirus from India that differs from the previously characterized Tomato leaf curl Sadasivanagar virus isolate Bangalore 1, ToLCBV (Z48182), To LCBV isolate Bangalore 4 (AF165098), and the bipartite ToLCNdV (U15015, U15016).
A Melting Pot of Old World Begomoviruses and Their Satellites Infecting a Collection of Gossypium Species in Pakistan
An exhaustive analysis of the diversity of begomoviruses and their satellites occurring in 15 Gossypium species that are maintained in an orchard in the vicinity of Multan has been conducted, finding a much greater diversity of alphasatellites in the non-cultivated cotton species than in G. hirsutum.
Tomato leaf curl geminivirus from India has a bipartite genome and coat protein is not essential for infectivity.
Comparison of sequences and other biological features of ToLCV-India with other geminiviruses showed that ToLCv-India is a distinct virus and is related to the WTGs from the Old World.
Further molecular characterization of weed-associated begomoviruses in Brazil with an emphasis on Sida spp
Begomoviruses are whitefly-transmitted, single-stranded DNA viruses that are often associated with weed plants. The aim of this study was to further characterize the diversity of begomoviruses
A Naturally Occurring Defective DNA Satellite Associated with a Monopartite Begomovirus: Evidence for Recombination between Alphasatellite and Betasatellite
The results provide the first evidence for recombination between two distinct types of satellites among geminivirus complex and highlight recombination as a driving force for geminvirus evolution.
