Abstract:
:Plants have evolved powerful immune systems to recognize pathogens and avoid invasions, but the genetic basis of plant susceptibility is less well-studied, especially to oomycetes, which cause disastrous diseases in many ornamental plants and food crops. In this research, we identified a negative regulator of plant immunity to the oomycete Phytophthora parasitica, AtRTP5 (Arabidopsis thaliana Resistant to Phytophthora 5), which encodes a WD40 repeat domain-containing protein. The AtRTP5 protein, which was tagged with green fluorescent protein (GFP), is localized in the nucleus and plasma membrane. Both the A. thaliana T-DNA insertion rtp5 mutants and the Nicotiana benthamiana RTP5 (NbRTP5) silencing plants showed enhanced resistance to P. parasitica, while overexpression of AtRTP5 rendered plants more susceptible. The transcriptomic analysis showed that mutation of AtRTP5 suppressed the biosynthesis of endogenous jasmonic acid (JA) and JA-dependent responses. In contrast, salicylic acid (SA) biosynthesis and SA-dependent responses were activated in the T-DNA insertion mutant rtp5-3. These results show that AtRTP5 acts as a conserved negative regulator of plant immunity to Phytophthora pathogens by interfering with JA and SA signalling pathways.
