During the long-term interaction between plants and phytophagous insects, plants generate diverse plant secondary metabolites (PSMs) to defend against insects, whereas insects persistently cause harm to plants by detoxifying PSMs. Xanthotoxin is an insect-resistant PSM that is widely found in plants. However, the understanding of detoxification mechanism of xanthotoxin in insects is still limited at present.

Comparative Analysis of Mitogenomes in Leafhopper Tribe Deltocephalini (Hemiptera: Cicadellidae: Deltocephalinae): Structural Conservatism and Phylogeny.

Ecol Evol

December 2024

Anhui Province Key Laboratory of Integrated Pest Management on Crops, Key Laboratory of Biology and Sustainable Management of Plant Diseases and Pests of Anhui Higher Education Institutes, School of Plant Protection Anhui Agricultural University Hefei Anhui China.

Previous studies on the gene order and composition of leafhopper mitochondrial genomes have revealed a high level of conservation in overall genome structure. Some members of Deltocephalinae, the largest subfamily, exhibit tRNA gene rearrangements; however, few mitogenomes have been sequenced in this group and the degree of structural variation within tribes remains unclear. In this study, we sequenced the complete mitogenomes of 14 species belonging to four genera of tribe Deltocephalini from China and compared them with the two previously reported mitogenomes for this tribe.

Department of Plant Pathology, College of Plant Protection, Anhui Agricultural University, Anhui Province Key Laboratory of Crop Integrated Pest Management, Key Laboratory of Biology and Sustainable Management of Plant Diseases and Pests of Anhui Higher Education Institutes, School of Plant Protection, Hefei, Anhui, China.

Non-host resistance (NHR) governs defense responses against a broad range of potential pathogen species in contrast with host resistance. To identify specific genes involved in disease resistance, we used a virus-induced gene-silencing screen in Nicotiana benthamiana and identified glycosyltransferase (NbGT) as an essential component of NHR. NbGT silencing enhanced the hypersensitivity response, reactive oxygen species response, and callose deposition in N.

Article Synopsis
  • Insecticide resistance in agricultural pests threatens the effectiveness of pest control strategies, and recent research points to odorant binding proteins (OBPs) as key players in this resistance.
  • Eleven OBPs were identified in Nilaparvata lugens, with OBP5 showing high expression in the head and a significant role in chlorpyrifos resistance, where its knockdown increased susceptibility to the insecticide.
  • The study confirmed that OBP5 binds to chlorpyrifos and its metabolite, with a specific amino acid crucial for this process, suggesting that targeting OBP5 may help in managing resistance by limiting the binding and sequestering of insecticides.
