title: A Turnip yellow mosaic virus infection system in Arabidopsis suspension cell culture.
abstract: Turnip yellow mosaic virus (TYMV) is a positive-strand RNA virus able to infect Arabidopsis thaliana. To establish a TYMV infection system in Arabidopsis cell culture, TYMV replicons with the capsid protein gene replaced by a reporter gene expressing the Sh ble protein conferring zeocin resistance were used to transfect Arabidopsis cells. Zeocin-resistant Arabidopsis calli were used to generate a suspension cell culture. Detection of viral proteins and RNAs after 18 months in culture demonstrated persistent replication of the replicon. The Arabidopsis cell culture yielded soluble, active replication complexes, providing a useful tool to study host factors involved in TYMV replication.
