Identification and Analysis of Potential Genes Regulated by an Alphasatellite (TYLCCNA) that Contribute to Host Resistance against Tomato Yellow Leaf Curl China Virus and Its Betasatellite (TYLCCNV/TYLCCNB) Infection in Nicotiana benthamiana

Viruses, 2019
Recently, begomovirus/betasatellite disease complexes were found to be associated with alphasatellites, and their presence modulated disease symptoms and/or viral DNA accumulation in infected plants.

Maintenance of an Old World Betasatellite by a New World Helper Begomovirus and Possible Rapid Adaptation of the Betasatellite [PDF]

Journal of Virology, 2009
ABSTRACT Begomoviruses (family Geminiviridae ) cause major losses to crops throughout the tropical regions of the world. Begomoviruses originating from the New World (NW) and the Old World (OW) are genetically distinct.

Roles of two distinct alphasatellites modulating geminivirus pathogenesis

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.

Molecular characterization and identification of bhendi yellow vein mosaic virus with satellite DNAs infecting okra plants of district Mardan, Pakistan

Egyptian Journal of Biological Pest Control, 2022
Background Bhendi or okra (Abelmoschus esculentus) is an important crop widely cultivated in the Indian subcontinent. The production of okra in tropical regions is constrained by several abiotic and biotic factors.

The merging of two dynasties--identification of an African cotton leaf curl disease-associated begomovirus with cotton in Pakistan. [PDF]

PLoS ONE, 2011
Cotton leaf curl disease (CLCuD) is a severe disease of cotton that occurs in Africa and Pakistan/northwestern India. The disease is caused by begomoviruses in association with specific betasatellites that differ between Africa and Asia. During survey of

BEGOMOVIRUSES AND BETASATELLITES ASSOCIATED WITH CLCuD

Biological and Clinical Sciences Research Journal, 2020
Begomoviruses are one of the major types of plant viruses. They are transmitted by whitefly and cause many diseases. The CLCuD is the most damaging disease of cotton. It is the vector of begomoviruses, namely as monpartite or bipartite begomoviruses. Bipartite begomoviruses are consisted of A and B DNA molecuales.

Suppression of nbe-miR1919c-5p Expression in Nicotiana benthamiana Enhances Tobacco Curly Shoot Virus and Its Betasatellite Co-Infection

Viruses, 2020
MicroRNAs (miRNAs) are non-coding but functional RNA molecules of 21–25 nucleotides in length. MiRNAs play significant regulatory roles in diverse plant biological processes.

Identification and Functional Analysis of Four RNA Silencing Suppressors in Begomovirus Croton Yellow Vein Mosaic Virus

Frontiers in Plant Science, 2022
Croton yellow vein mosaic virus (CYVMV), a species in the genus Begomovirus, is a prolific monopartite begomovirus in the Indian sub-continent. CYVMV infects multiple crop plants to cause leaf curl disease.

The transcriptional regulator JAZ8 interacts with the C2 protein from geminiviruses and limits the geminiviral infection in Arabidopsis

Journal of Integrative Plant Biology, Volume 65, Issue 7, Page 1826-1840, July 2023., 2023
Jasmonate signaling is emerging as a battlefield in plant‐geminivirus interactions. Plant JAZ8, a member of the JAZ family of transcriptional regulators of jasmonate signaling, interacts with the geminiviral C2 protein in the nuclei of infected cells and can limit the viral infection.

Demonstration of Insect Vector-Mediated Transfer of a Betasatellite between Two Helper Viruses. [PDF]

Viruses
Begomoviruses, transmitted by the whitefly Bemisia tabaci, pose significant threats to global agriculture due to their severe impact on various crops. Among the satellite molecules associated with begomoviruses, betasatellites play a crucial role in enhancing disease severity and yield losses.
