The ''Brown planthopper induced008a'' (''Bphi008a''; AY256682) gene of rice (''Oryza sativa'') enhances the plant’s resistance to the brown planthopper (BPH; ''Nilaparvata lugens''). BPH feeding rapidly initiated the ethylene (ET) signaling pathway and up-regulated ''Bphi008a'' transcript levels after 6 to 96 h of feeding. In contrast, blocking ethylene transduction (using 1-methylcyclopropene) reduced ''Bphi008a'' transcript levels in wild-type plants fed upon by BPH. Because ''Bphi008a'' is a downstream gene of the Et signaling pathway in rice. The overexpressed (OE) plants had greater resistance to the BPH than wildtype plants (Fig. 1wD). In contrast, the change in susceptibility of rice to the BPH caused by RNAi of ''Bphi008a'' was not obvious. The level of ''Bphi008a'' expression affects BPH feeding on the phloem of rice (Fig. 1wE). The ''Bphi008a'' expression enhances rice resistance to the BPH by impairing BPH feeding (Fig.1wF). The ''Bphi008a'' can be phosphorylated by rice Mitogen-activated Protein Kinase5 (OsMPK5). Yeast two-hybrid assays demonstrated that the carboxyl-terminal proline-rich region of ''Bphi008a'' interacts directly with this kinase, and this interaction occurs in the nucleus. Subsequently, we found that ''Bphi008a'' up-regulation and down-regulation were accompanied by different changes in transcription levels of OsMPK5, OsMPK12, OsMPK13, and OsMPK17 in transgenic plants (Fig. 2w). Immunoblot analysis also showed that the OsMPK5 protein level increased in overexpressing plants and decreased in RNA interference plants after BPH feeding(Fig. 3w, A and B). The ''Bphi008a'' Overexpression Enhances Levels of AP2/ERF Transcription Factors and Defense-Related Genes. Yeast two-hybrid screening results showed that a clear interaction between ''Bphi008a''and a b-ZIP transcription factor (OsbZIP60), but a weak interaction between  ''Bphi008a'' and a RNA polymerase polypeptide (SDRP) (Fig. 4wB). Furthermore, analysis of OsbZIP60 expression levels in wild-type and transgenic plants after BPH feeding from 0 to 96 h (Fig. 4wD) indicated that ''Bphi008a'' (possibly phosphorylated) might form a transcriptional complex with OsbZIP60 and SDRP in vivo that activates the transcription of target genes.<ref name="ref1" />
