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.

Temporal changes in the levels of virus and betasatellite DNA in B. tabaci feeding on CLCuD affected cotton during the growing season [PDF]

Frontiers in Microbiology
Cotton, a key source of income for Pakistan, has suffered significantly by cotton leaf curl disease (CLCuD) since 1990. This disease is caused by a complex of phylogenetically-related begomovirus (genus Begomovirus, family Geminiviridae) species and a ...

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 ...

The C5 protein encoded by Ageratum leaf curl Sichuan virus is a virulence factor and contributes to the virus infection

Molecular Plant Pathology, Volume 22, Issue 9, Page 1149-1158, September 2021., 2021
ALCScV C5 protein is a virulence factor and enhances the pathogenicity of PVX in Nicotiana benthamiana. Mutational analyses showed that C5 is important for disease symptom formation and affects ALCScV replication in infected plants. Abstract Earlier reports have indicated that begomoviruses encode four proteins (AC1/C1, AC2/C2, AC3/C3, and AC4/C4 ...
