A pentatomomorpha-specific salivary protein activates plant immunity and is critical for insect feeding
A pentatomomorpha-specific salivary protein activates plant immunity and is critical for insect feeding

The stinkbug Riptortus pedestris, notorious for inducing soybean staygreen-like syndrome, employs a range of salivary proteins to manipulate the host plant for its benefit. Here, we show that RpSP1, a salivary protein specific to Pentatomomorpha, triggers plant defense responses in multiple plant species. RpSP1 interacts with and stabilizes a HSP40 family protein GmSPIP1 and is dependent on GmSPIP1 to induce cell death.
