Abstract

Dysfunction of susceptibility genes leads to broad-spectrum resistance (BSR) in plants. A rice ubiquitin E3 ligase degrades an ortholog of plant thermosensor to positively regulate blast resistance. Gao et al. recently showed that this E3 ligase also ubiquitinates a Ca²⁺-sensor to mediate rice BSR, extending our knowledge of susceptibility protein ubiquitination for plant BSR.

Keywords: E3 ubiquitin ligase; broad-spectrum resistance; plant immunity; susceptibility gene; ubiquitination.
