Roles of two distinct alphasatellites modulating geminivirus pathogenesis [PDF]

Virology Journal, 2021
Background Alphasatellites are small coding DNA satellites frequently associated with a begomovirus/betasatellite complex, where they are known to modulate virulence and symptom development.

Effects of an Alphasatellite on the Life Cycle of the Nanovirus Faba Bean Necrotic Yellows Virus. [PDF]

J Virol, 2022
International audienceNanoviruses are plant viruses with a multipartite single-stranded DNA (ssDNA) genome. Alphasatellites are commonly associated with nanovirus infections, but their putative impact on their helper viruses is unknown. In this study, we

Unveiling Common Bean (Phaseolus vulgaris L) RNA- and DNA-Based Virome in Western Kenya: Insights From Metatranscriptomic and Metagenomic Signatures [PDF]

Advances in Virology
Common bean (Phaseolus vulgaris L) is Kenya’s second most important agricultural product after maize, serving as a vital source of protein for many rural families in Western Kenya. However, viral diseases caused by RNA and DNA viruses greatly impair bean

Divergent Cotton leaf curl Multan betasatellite and three different alphasatellite species associated with cotton leaf curl disease outbreak in Northwest India. [PDF]

PLoS ONE
Cotton leaf curl disease (CLCuD) is a major constraint for production of cotton (Gossypium sp.) in Northwest India. CLCuD is caused by a monopartite, circular ssDNA virus belonging to the genus Begomovirus in association with betasatellites and ...

The Association between New World Alphasatellites and Bipartite Begomoviruses: Effects on Infection and Vector Transmission [PDF]

Pathogens, 2021
Begomoviruses can be found in association with alphasatellites, which are capable of autonomous replication but are dependent on the helper begomovirus for systemic infection, encapsidation and vector transmission.

A new genus of alphasatellites associated with banana bunchy top virus in Southeast Asia. [PDF]

Virus Evol, 2023
Abstract Autonomously replicating alphasatellites (family Alphasatellitidae) are frequently associated with plant single-stranded (ss)DNA viruses of the families Geminiviridae, Metaxyviridae, and Nanoviridae. Alphasatellites encode a single replication-initiator protein (Rep) similar to Rep proteins of helper viruses and depend on helper

A novel geminivirus-derived 3' flanking sequence of terminator mediates the gene expression enhancement. [PDF]

Plant Biotechnol J
Summary Exploring the new elements to re‐design the expression cassette is crucial in synthetic biology. Viruses are one of the most important sources for exploring gene expression elements. In this study, we found that the DNA sequence of the SBG51 deltasatellite from the Sweet potato leaf curl virus (SPLCV) greatly enhanced the gene expression when ...

Identification and Genome Characterization of Begomovirus and Satellite Molecules Associated with Lettuce (Lactuca sativa L.) Leaf Curl Disease [PDF]

Plants
Lettuce (Lactuca sativa L.) plants showing leaf curl and vein enation symptoms were found in Yunnan province, China. PCR detection with genus-specific primers revealed that symptomatic lettuce plants were infected with Begomovirus.
