Cold suppresses virus accumulation and alters the host transcriptomic response in the turnip mosaic virus-Arabidopsis halleri system.

ABSTRACT: Since plant viruses cause lifelong infections, virus-plant interactions are exposed to large temperature fluctuations in evergreen perennials. In such circumstances, virus-plant interactions are expected to change significantly between the warm and cold seasons. However, few studies have investigated the effects of cold temperatures on virus-plant interactions. Here, we show that in a persistent infection system of the turnip mosaic virus (TuMV)-Arabidopsis halleri, cold temperatures lead to slow viral replication/spreading within the host, attenuated host symptoms, and cold-specific transcriptomic responses. Many differentially expressed genes (DEGs) were detected between virus-inoculated and mock-inoculated plants under warm and cold conditions; however, the sets of DEGs and response tim
