The Tomato Transcription Factor RAV Affects the Systemic Infection of TYLCV by Interacting With V2. [PDF]

Mol Plant Pathol
This study investigated the interaction between TYLCV V2 and tomato transcription factor SlRAV2: SlRAV2 enhances the RSS activity of V2 by strengthening its binding to 21‐nt ds‐siRNA, V2 enhances SlRAV2's SlPR1 promoter regulation and their interaction inhibits systemic spread of the virus from infiltrated leaves to systemic leaves.

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses. [PDF]

Adv Sci (Weinh)
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Virus-Inducible Activation of Hypersensitive Response Confers Broad-Spectrum Resistance to Diverse Viruses in Plants. [PDF]

Mol Plant Pathol
Using a virus‐inducible promoter to drive the expression of the Avr4/Cf‐4 gene pair can trigger a hypersensitive response upon viral infection, which confers plants broad‐spectrum resistance to geminiviruses. ABSTRACT The hypersensitive response (HR) is a powerful plant defence mechanism that restricts pathogen spread through localised cell death ...

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection. [PDF]

New Phytol
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

Leaf Plasmodesmata Respond Differently to TMV, ToBRFV and TYLCV Infection [PDF]

Plants, 2021
Macromolecule and cytosolic signal distribution throughout the plant employs a unique cellular and intracellular mechanism called plasmodesmata (PD). Plant viruses spread throughout plants via PD using their movement proteins (MPs). Viral MPs induce changes in plasmodesmata’s structure and alter their ability to move macromolecule and cytosolic signals.

Development of a method to rapidly assess resistance/susceptibility of Micro-Tom tomatoes to Tomato yellow leaf curl virus via agroinoculation of cotyledons

BMC Research Notes, 2021
Objective Tomato yellow leaf curl virus (TYLCV) is one of the pathogens severely damaging tomato crops. Therefore, methods to treat or prevent TYLCV infection need to be developed.

Transcriptome Profiling Unravels the Involvement of Phytohormones in Tomato Resistance to the Tomato Yellow Leaf Curl Virus (TYLCV)

Horticulturae, 2022
Tomato yellow leaf curl virus (TYLCV) is a serious pathogen transmitted by the whitefly (Bemisia tabaci). Due to the quick spread of the virus, which is assisted by its vector, tomato yield and quality have suffered a crushing blow.

TYLCV-IS76 and TYLCV-IS141: fraternal but not identical tomato yellow leaf curl twin recombinant viruses [PDF]

, 2019
Tomato yellow leaf curl virus (TYLCV), tomato yellow leaf curl Sardinia virus (TYLCSV) and TYLCV/TYLCSV recombinants (Begomovirus, Geminiviridae) are responsible of the damaging tomato leaf curl disease (TYLCD) in the Mediterranean. Tomato cultivars having the Ty-1 resistance gene were deployed in the Mediterranean Basin in the 2000s.

Displacement of Tomato Yellow Leaf Curl Virus (TYLCV)-Sr by TYLCV-Is in Tomato Epidemics in Spain [PDF]

Phytopathology®, 1999
A progressive displacement of tomato yellow leaf curl virus (TYLCV)-Sr by TYLCV-Is was observed in tomato epidemics in southern Spain based on incidence data of both virus species obtained during surveys conducted between 1996 and 1998. Ecological factors that might be involved in such a displacement, such as competition of TYLCV-Sr and TYLCV-Is in ...

Full-length genome sequencing and phylogeny of severe strain isolates of Tomato yellow leaf curl virus (TYLCV-IL) originating from Datura stramonium L. in Bojnurd region, Iran [PDF]

مجله بیوتکنولوژی کشاورزی, 2014
Tomato yellow leaf curl virus (TYLCV) and  a complex of  ten virus species and their strains referred to as TYLCV-like viruses cause damage on tomato (Solanum  lycopersicum L.) crops in tropical, subtropical and temperate regions of the world.
