Geminivirus: Indian Scenario

2016
Geminiviruses are a diverse group of plant virus which infects several crop species in India. Based on host range, insect vector, and genome organization, geminiviruses are classified into four genera: Begomovirus, Curtovirus, Topocuvirus, and Mastrevirus.

Role of methylation during geminivirus infection

2020
Epigenetic marks are reversible molecular changes associated to DNA or histones, and are important regulators of gene expression and genome plasticity. In plants, the covalent binding of a methyl group to cytosine or to the lysine 9 residue of H3 histone is promoting transcriptional silencing.

Geminivirus Resistance Strategies

2019
Geminiviruses are a major threat to world agriculture, and breeding resistant crops against these viruses is one of the major challenges faced by both plant pathologists and biotechnologists. In the past, most of these strategies follow the conceptual development ranging from coat protein-mediated restricted viral propagation to the expression of ...

Geminivirus disease complexes: the threat is spreading

Trends in Plant Science, 2006
Symptom-modulating DNA satellites associated with geminiviruses have come to our attention only recently but have proven to be widespread, associated with many diseases throughout the Old World, and economically significant, particularly in developing countries.

Specificity of Bipartite Geminivirus Movement Proteins

Virology, 1993
Pseudorecombinants produced by exchanging genome components (DNAs A and B) of the geminiviruses African cassava mosaic virus (ACMV) and Indian cassava mosaic virus (ICMV), ACMV, and tomato golden mosaic virus (TGMV), and TGMV and abutilon mosaic virus (AbMV) are not infectious in their common host Nicotiana benthamiana.

Characterization of DNA intermediates of an arising geminivirus

Virus Research, 2007
Weeds of the genus Sida collected in Brazil have harbored several geminiviruses persistently over decades of vegetative propagation. They serve as cradles for new geminiviruses originating from pseudorecombination (reassortment) or molecular recombination, as has been exemplified by Sida micrantha mosaic-associated viruses (SimMV).

Geminivirus: Biolistic Inoculation and Molecular Diagnosis

2008
The Geminiviridae family is a large family of plant viruses that has single-stranded DNA genomes and infects a large variety of crop species. In this chapter, we describe a biolistic inoculation protocol that has been successfully used to propagate new species of geminivirus in permissive hosts with total DNA extracted from infected plants. This allows

Strategies for the control of geminivirus diseases

Seminars in Virology, 1993
Abstract Geminiviruses are unique plant DNA viruses that frequently cause significant yield reductions in a wide range of cereal, vegetable and fibre crops. Encouraging progress has recently been made towards the control of geminiviruses that infect dicotyledonous plants.

Geminivirus–Vector Relationship

2019
Geminiviruses are the most abundant plant viruses. This group of ssDNA viruses infects a wide range of hosts including weeds, ornamentals, as well as economically important crops and is widely distributed on the planet Earth. Geminiviruses cause some of the most damaging and economically important diseases of crop plants.

Geminivirus genomes.

Microbiological sciences, 1990
The geminiviruses are unusual plant viruses containing circular single-stranded DNA. The sequences and organization of several of their genomes are described, and recent experiments towards understanding their replication, gene expression and gene functions are discussed.
