This study found that the SA-binding protein SABP3 (AtCA1) of Arabidopsis thaliana has an In-vitro and In-vivo interaction with TuMV HC-Pro (TuHC), and the AtCA1-Knockout (ca1) plants were more susceptible to TuMV. From our results, TuMV HC-Pro interacts and down-regulates AtCA1 expression to reduce SA accumulation for weaken the plant defense response to the virus.
