Oviposition fluid protein NlOFP1 in the brown planthopper suppresses rice plant defenses.

Oviposition fluid protein NlOFP1 from the brown planthopper Nilaparvata lugens suppresses rice plant defense responses, linked to reduced lignin and salicylic acid in transgenic rice.

• Why it matters: Oviposition fluid proteins are involved in early plant recognition, but how specific proteins modulate plant defenses during pest reproduction is not well defined.
• What they did: The study characterized NlOFP1 from ovarian follicular cells and tested its effects by silencing NlOFP1 in Nilaparvata lugens and by transgenic rice overexpressing NlOFP1, including interaction mapping with OsFeS.
• The result: NlOFP1 silencing in Nilaparvata lugens decreased honeydew secretion, fecundity, and egg hatching rate, while NlOFP1 overexpression in rice weakened defenses and interacted with OsFeS to partially impair its chloroplast import.
