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 ...

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 ...

A newly emerging alphasatellite of banana bunchy top virus affects viral replication, transcription, siRNA production and transmission by aphids [PDF]

, 2021
Banana bunchy top virus (BBTV) is a six-component ssDNA nanovirus transmitted by aphids, causing severe disease of monocot Musa plants, which originates from South-East Asia. Asian BBTV isolates are often associated with self-replicating alphasatellites.

Single nucleotide resolution maps of Illumina sRNA-seq reads representing viral siRNAs from BBTV-infected Cavendish banana plants with or without DRC alphasatellite.

, 2022
For each of the two conditions, i.e. without (BBTV-alpha) and with (BBTV+alpha) alphasatellite, Illumina 20–25 nt reads of the three biological replicates (leaf tissues of three plants) were combined and mapped simultaneously onto the reference sequences

The AP2 transcription factor NtERF172 confers drought resistance by modifying NtCAT

Plant Biotechnology Journal, Volume 18, Issue 12, Page 2444-2455, December 2020., 2020
Summary Drought stress often limits plant growth and global crop yields. Catalase (CAT)‐mediated hydrogen peroxide (H2O2) scavenging plays an important role in the adaptation of plant stress responses, but the transcriptional regulation of the CAT gene in response to drought stress is not well understood.

Role of Alphasatellite in Begomoviral Disease Complex

Biological Sciences - PJSIR, 2016
A circular single stranded satellite, called as alphasatellite (initially identified as DNA-1), wascharacterised and confirmed to be associated with the Geminivirus begomovirus-betasatellite complexes.Alphasatellites are single stranded DNA (ssDNA) components, frequently accompanying with monopartitebegomovirus or some time with bipartite begomovirus ...

Alphasatellitidae: a new family with two subfamilies for the classification of geminivirus- and nanovirus-associated alphasatellites [PDF]

Archives of Virology, 2018
Nanoviruses and geminiviruses are circular, single stranded DNA viruses that infect many plant species around the world. Nanoviruses and certain geminiviruses that belong to the Begomovirus and Mastrevirus genera are associated with additional circular, single stranded DNA molecules (~ 1-1.4 kb) that encode a replication-associated protein (Rep). These
