The intracellular immune receptor family of nucleotide-binding domain leucine-rich repeat–containing proteins (NLRs) perceive translocated pathogen effector proteins and execute a robust immune response, including programmed cell death. Many plant NLRs have functionally specialized to sense pathogen effectors (sensor NLRs) or to execute immune signalling (helper NLRs). Sub-functionalized NLRs form a network-type receptor system known as the NLR network. In this review, we highlight the concept of NLR networks, discussing how they are formed, activated, and regulated. Two main types of NLR networks have been described in plants: the ADR1/NRG1 network and the NRC network. In both networks, multiple helper NLRs function as signalling hubs for sensor NLRs and cell surface–localized immune receptors. Additionally, the networks are regulated at the transcriptional and posttranscriptional levels, as well as being modulated by other host proteins to ensure proper network activation and prevent autoimmunity. Plant pathogens in turn have converged on suppressing NLR networks, thereby facilitating infection and disease. Understanding the NLR immune system at the network level could inform future breeding programs by highlighting the appropriate genetic combinations of immunoreceptors to use while avoiding deleterious autoimmunity and suppression by pathogens. カテゴリーLatest-Research 投稿ナビゲーション 前の投稿前 Publications リストを更新しました次の投稿次 （メディア掲載）毎日新聞で当研究室のコムギ遺伝資源保存を取り上げていただきました News The NRC0 gene cluster of sensor and helper NLR immune receptors is functionally conserved across asterid plants Jurassic NLR: Conserved and dynamic evolutionary features of the atypically ancient immune receptor ZAR1 シンポジウムと展示の開催のお知らせ Reproductive Responses to Increased Shoot Density and Global Change Drivers in a Widespread Clonal Wetland Species, Schoenoplectus americanus Disentangling the complex gene interaction networks between rice and the blast fungus identifies a new pathogen effector 〒617-0001 京都府向日市物集女町中条１番地 TEL:075-921-0652 FAX:075-932-8063   Link {"visible_panels":"9","width":"900","height":"300","orientation":"horizontal","panel_distance":"0","max_openedaccordion_size":"100%","open_panel_on":"click","shadow":"true","autoplay":"true","mouse_wheel":"false"} Contact us   © 2024 Crop Evolution Lab.
