Planthopper-Secreted Salivary Calmodulin Acts as an Effector for Defense Responses in Rice
Frontiers in Plant Science, 2022 The brown planthopper (Nilaparvata lugens, BPH) and small brown planthopper (Laodelphax striatellus, SBPH) are major pests of rice (Oryza sativa) in Asia. These piercing-sucking insects secrete saliva into the host during feeding.

Insects, 2021 The brown planthopper, Nilaparvata lugens (Stål), is a key challenge to rice production in Asia. Outbreaks of planthoppers are associated with excessive fertilizer applications; consequently, we examined planthopper interactions with susceptible ...

Planthopper salivary sheath protein LsSP1 contributes to manipulation of rice plant defenses
Nature Communications, 2023 Salivary elicitors secreted by herbivorous insects can be perceived by host plants to trigger plant immunity. However, how insects secrete other salivary components to subsequently attenuate the elicitor-induced plant immunity remains poorly understood ...

Sakuranetin protects rice from brown planthopper attack by depleting its beneficial endosymbionts
Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance Herbivorous insects commonly harbor beneficial microbial endosymbionts that provide nutritional benefits to their hosts. These microbes may be the targets of plant antiherbivore defense compounds, but such a role for plant defenses has not ...

Bph30 confers resistance to brown planthopper by fortifying sclerenchyma in rice leaf sheath.
Molecular Plant, 2021 Phloem-feeding insects cause massive losses in agriculture and horticulture. Host plant-mediated resistance to phloem-feeding insects is often mediated by changes in phloem composition to deter insect settling, feeding and viability.

bioRxiv, 2022 Vitellogenins are essential for the development and fecundity of insects, but these proteins may also betray them, as we show here. We found that the small N-terminal subunit of vitellogenins of the planthopper Nilaparvata lugens (NlVgN) triggers strong ...

Vitellogenin from planthopper oral secretion acts as a novel effector to impair plant defenses.
New Phytologist, 2021 Vitellogenin (Vg) is a well-known nutritious protein involved in reproduction in nearly all oviparous animals, including insects. Recently, Vg has been detected in saliva proteomes of several piercing-sucking herbivorous arthropods, including the small ...

Planthopper-Secreted Salivary Disulfide Isomerase Activates Immune Responses in Plants
Frontiers in Plant Science, 2021 The small brown planthopper (Laodelphax striatellus; SBPH) is a piercing-sucking insect that secretes salivary proteins into its plant host during feeding.

Insects, 2021 Simple Summary Plant defensive compounds are the effective measures for host plants to defend against herbivorous insects, whereas in turn insects evolve an array of detoxifying enzymes to overcome the resistance of these compounds.
