Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
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.

Viral and Host Factors Involved in Host Gain and Host Loss by Tomato Leaf Curl Begomoviruses in Tomato and Cucumbers. [PDF]

Mol Plant Pathol
Begomoviruses have jumped hosts between tomatoes and cucumbers, and we found that a short region (transcriptional activator and replication enhancer proteins, TrAp and REn) of tomato leaf curl New Delhi virus is mainly responsible for host jump. ABSTRACT Begomoviruses transmitted by whiteflies cause severe crop losses worldwide.
