First Report of Cabbage leaf curl virus (Family Geminiviridae) in Georgia
Cabbage and collard greens were inflicted with a previously undescribed virus-like disease during the fall 2000. Symptoms on leaves were yellow spots, vein clearing, mosaic, curling, and puckering. Symptomatic plants were widespread in Brooks, Colquitt, Grady, and Pierce counties in Georgia.

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]
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
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.

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.
