G-Box Factors 14-3-3 Proteins Negatively Regulate <i>Cucumber Mosaic Virus</i> Infection Tolerance in <i>Arabidopsis</i>.

ABSTRACT: Cucumber mosaic virus (CMV), a representative species of the genus Cucumvirus in the family Bromoviridae, is globally distributed and infects over 1200 monocot and dicot plants. 14-3-3 proteins serve as molecular adaptors that bind phosphorylated target proteins and play significant roles in multiple signaling pathways, including plant growth and development, hormone signaling, and responses to abiotic and biotic stimuli. Although an increasing body of evidence supports the prominent roles of 14-3-3 proteins in regulating plant immunity, their specific roles in plant responses to CMV infection remain unclear. Here, we demonstrate that 14-3-3λ and 14-3-3κ knockout Arabidopsis plants display enhanced tolerance to CMV infection, with significantly sup
