20.500.12556/DiRROS-19640 A model species for agricultural pest genomics the genome of the Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae) The Colorado potato beetle is one of the most challenging agricultural pests to manage. It has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable climates during its global invasion, and, notably, to rapidly evolve insecticide resistance. To examine evidence of rapid evolutionary change, and to understand the genetic basis of herbivory and insecticide resistance, we tested for structural and functional genomic changes relative to other arthropod species using genome sequencing, transcriptomics, and community annotation. Two factors that might facilitate rapid evolutionary change include transposable elements, which comprise at least 17% of the genome and are rapidly evolving compared to other Coleoptera, and high levels of nucleotide diversity in rapidly growing pest populations. Adaptations to plant feeding are evident in gene expansions and differential expression of digestive enzymes in gut tissues, as well as expansions of gustatory receptors for bitter tasting. Surprisingly, the suite of genes involved in insecticide resistance is similar to other beetles. Finally, duplications in the RNAi pathway might explain why Leptinotarsa decemlineata has high sensitivity to dsRNA. The L. decemlineata genome provides opportunities to investigate a broad range of phenotypes and to develop sustainable methods to control this widely successful pest. colorado potato beetle genome Leptinotarsa decemlineata true false true Angleški jezik Latinski jezik Neznano 2024-07-23 03:54:21 2024-07-24 12:41:23 2024-07-25 04:14:49 0000-00-00 00:00:00 2018 0 0 Nasl. z nasl. zaslona; Opis vira z dne 26. 2. 2018; str. 1-18 Vol. 8 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2018-01-31 575.111 2045-2322 10.1038/s41598-018-20154-1 4626767 HttP://dx.doi.org/10.1038/s41598-018-20154-1 1 b7d55265-4885-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27138 RAZ_Schoville_Sean_D._2018.pdf RAZ_Schoville_Sean_D._2018.pdf 1 0851FF11D3603578C8F8B468FF660318 da09d72b0b1c304f1b3279b6717ee096b64d0bc7b02502a6d93c2f0f65ac4410 84bc9c57-4999-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27297 Nacionalni inštitut za biologijo 0 0 0
