The green rice leafhopper, Nephotettix cincticeps (Hemiptera: Cicadellidae), salivary protein NcSP75 is a key effector for successful phloem ingestion.

ABSTRACT: Nephotettix cincticeps, a prevalent rice pest, injects gelling and watery saliva into plant tissues during the sucking process. Certain components within the saliva are believed to interact with plant cellular constituents and play important roles in overcoming host plant defense responses. Based on our previous analysis of the salivary gland transcriptome and secreted saliva proteome of N. cincticeps, in this study, we analyzed the biological functions of salivary protein, NcSP75 (N. cincticeps salivary protein 75 kD). NcSP75, a salivary glands-specific gene, showed low similarities to any previously reported sequences. Knockdown of NcSP75 by RNA interference (RNAi) reduced the longevity of treated nymphs to approximately half of the longevity of controls and caused severe developmental r
