Physiologia 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.

A novel circumscription and classification for Neurolaeneae (Asteraceae)
TAXON, Volume 75, Issue 1, February 2026.Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...
