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

Molecular 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.

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

PLoS 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 ...

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

Annals 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.

Using Abscisic Acid and Leaf Removal to Alter the Sensory Properties of Pinot Noir Wine Made From Grapevines With Grapevine Red Blotch Disease

Journal of Food Quality, Volume 2026, Issue 1, 2026.
Grapevine red blotch disease (GRBD) poses economic concerns for the US wine industry due to impacts on fruit and wine quality. This study investigated the impact of two vineyard management techniques, cluster‐zone leaf removal and abscisic acid (ABA) application, to alter the sensory characteristics of Pinot Noir wines made from GRBD‐positive vines ...
