Insights Into Virus‐Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

open access: yesPLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

The Tomato Transcription Factor RAV Affects the Systemic Infection of TYLCV by Interacting With V2

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
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.

Identification and characterization of a cucumber accession resistant to tomato leaf curl New Delhi virus

open access: yesAnnals of Applied Biology, Volume 188, Issue 1, Page 182-194, January 2026.
Tomato leaf curl New Delhi virus (ToLCNDV) causes significant yield and fruit quality losses in cucurbit crops, particularly in the Mediterranean region. We identified a new source of resistance to ToLCNDV in cucumber (accession ABS.PE.045) and mapped resistance to four genomic intervals in chromosomes 1, 2, 6, and 7.
