Geminiviruses employ host DNA glycosylases to subvert DNA methylation-mediated defense [PDF]

Nature Communications, 2022
Plants tightly regulate DNA methylation to regulate gene expression. Here, the authors show that the tomato yellow leaf curl China virus βC1 protein interacts with plant DNA glycosylases to promote demethylation of viral DNA and promote virulence.

βC1 of chili leaf curl betasatellite is a pathogenicity determinant [PDF]

Virology Journal, 2011
Background Cotton leaf curl disease in the Indian subcontinent is associated with several distinct begomoviruses that interact with a disease-specific DNA satellite named Cotton leaf curl Multan betasatellite (CLCuMB). However, we have recently reported

Role of complementary-sense genes and intergenic region of beet curly top virus in intermolecular recombination frequency upon local infection in plants [PDF]

Journal of Virology
Intermolecular recombination is a critical process in the evolution of plant viruses, including geminiviruses. In this study, we investigated the impact of geminiviral factors on the homologous recombination frequency (HRF) in a model system involving ...

Viral action on the auxin signaling repressor IAA16 reveals a conserved negative regulator of plant growth and immunity

Cell Reports
Summary: Crop breeding endeavors are frequently constrained by the growth-defense trade-off, and uncoupling this trade-off remains challenging due to the limited knowledge of master regulators.

Tomato SlSnRK1 Protein Interacts with and Phosphorylates βC1, a Pathogenesis Protein Encoded by a Geminivirus β-Satellite1[C][W][OA]

Plant Physiology, 2011
The βC1 protein of tomato yellow leaf curl China β-satellite functions as a pathogenicity determinant. To better understand the molecular basis of βC1 in pathogenicity, a yeast two-hybrid screen of a tomato (Solanum lycopersicum) cDNA library was carried

CLCuMuB βC1 represses JA responses though interfering with the integrity of SCFCOI1.

, 2016
(A) Total root length of HA-βC1 transgenic (#2 HA-βC1 and #3 HA-βC1) and wild-type (#2 WT and #3 WT) N. benthamiana seedlings was measured every 24 h beginning at the 6th day after sowing (n ≥11). Bars represent SEM. #2 HA-βC1 and #2 WT were presented on

N-terminal acetylation of the βC1 protein encoded by the betasatellite of tomato yellow leaf curl China virus is critical for its viral pathogenicity.

Virology, 2023
N-terminal acetylation (N-acetylation) is one of the most common protein modifications and plays crucial roles in viability and stress responses in animals and plants. However, very little is known about N-acetylation of viral proteins.

The N-terminal domain of NbSKP1.1 interacts with CLCuMuB βC1 in yeast.

, 2016
Growth of SKY48 yeast strains containing NLS-LexA BD-CLCuMuB βC1 (BD-βC1) transformed with AD fused full length, N-terminal fragment (N98aa), C-terminal fragment (C57aa) of NbSKP1.1 or AD (control) on Leu-containing (Leu+) and Leu-deficient (Leu−) medium

Mimic Phosphorylation of a βC1 Protein Encoded by TYLCCNB Impairs Its Functions as a Viral Suppressor of RNA Silencing and a Symptom Determinant

Journal of Virology, 2017
Phosphorylation of the βC1 protein encoded by the betasatellite of tomato yellow leaf curl China virus (TYLCCNB-βC1) by SNF1-related protein kinase 1 (SnRK1) plays a critical role in defense of host plants against geminivirus infection in ...

Geminivirus Betasatellite-Encoded βC1 Protein Exhibits Novel ATP Hydrolysis Activity That Influences Its DNA-Binding Activity and Viral Pathogenesis

Journal of Virology, 2021
Most satellites influence the pathogenesis of their helper viruses. Here, we characterized the novel molecular function of βC1, a nonstructural pathogenicity determinant protein encoded by a betasatellite.
