Recombinant tritin protein exhibits antiviral activity against zucchini yellow mosaic virus.

Background: Ribosome-inactivating proteins (RIPs) are a group of proteins known to inhibit protein synthesis and contribute to plant defense responses. Although the antiviral properties of various RIPs have been demonstrated, the antiviral potential of tritin, a type 1 RIP from bread wheat (Triticum aestivum L.), remains unexplored.
