Geminivirus genes and vectors

Trends in Genetics, 1989
The geminiviruses are very small plant viruses with circular single-stranded DNA genomes. Recent advances have identified genes involved in replication, spread of virus or DNA in the plant, and insect transmission. Gene replacement experiments suggest that useful plant gene expression vectors can be constructed from these viruses.

Geminivirus structure and assembly

2020
The geminivirus capsid architecture is unique and built from twinned pseudo T=1 icosahedrons with 110 copies of the coat protein (CP). The CP is multifunctional. It performs various functions during the infection of a wide range of agriculturally important plant hosts.

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.

Geminivirus disease complexes: an emerging threat

Trends in Plant Science, 2003
Small circular single-stranded DNA satellites have recently been isolated from plants infected with whitefly-transmitted monopartite begomoviruses. The satellites, named DNA beta, depend on the helper viruses for their proliferation and, in turn, are required for helper virus accumulation and symptom expression.

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.

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 C4 protein alters Arabidopsis development

Protoplasma, 2009
The C4 protein of beet curly top virus [BCTV-B (US:Log:76)] induces hyperplasia in infected phloem tissue and tumorigenic growths in transgenic plants. The protein offers an excellent model for studying cell cycle control, cell differentiation, and plant development. To investigate the role of the C4 protein in plant development, transgenic Arabidopsis

Structure and replication of geminivirus genomes

Journal of Cell Science, 1987
ABSTRACT The geminiviruses are a group of plant viruses containing single-stranded (ss) DNA in particles comprising two quasi-icosahedral units. Some are transmitted by whiteflies, others by leafhoppers. Comparisons were made of the genome organization and expression of cassava latent virus (CLV) and maize streak virus (MSV) and beet ...
