Proxitome profiling reveals a conserved SGT1-NSL1 signaling module that activates NLR-mediated immunity

Suppressor of G2 allele of skp1 (SGT1) is a highly conserved eukaryotic protein that plays a vital role in growth, development, and immunity in both animals and plants. Although some SGT1 interactors have been identified, the molecular regulatory network of SGT1 remains unclear. SGT1 serves as a co- chaperone to stabilize protein complexes such as the nucleotide-binding leucine-rich repeat (NLR) class of immune receptors, thereby positively regulating plant immunity. SGT1 has also been found to be associated with the SKP1-Cullin-F-box (SCF) E3 ubiquitin ligase complex. However, whether SGT1 targets immune repressors to coordinate plant immune activation remains elusive. In this study, we constructed a toolbox for TurboID- and split-TurboID-based proximity labeling (PL) assays in Nicotiana benthamiana and used the PL toolbox to explore the SGT1 interactome during pre- and post-immune activation. The comprehensive SGT1 interactome network we identified highlights a dynamic shift from proteins associated with plant development to those linked with plant immune responses. We found that SGT1 interacts with Necrotic Spotted Lesion 1 (NSL1), which negatively regulates salicylic acid-mediated defense by interfering with the nucleocytoplasmic trafficking of non-expressor of pathogenesis-related genes 1 (NPR1) during N NLR-mediated response to tobacco mosaic virus. SGT1 promotes the SCF-dependent degradation of NSL1 to facilitate immune activation, while salicylate-induced protein kinase-mediated phosphorylation of SGT1 further potentiates this process. Besides N NLR, NSL1 also functions in several other NLRmediated immunity. Collectively, our study unveils the regulatory landscape of SGT1 and reveals a novel SGT1-NSL1 signaling module that orchestrates plant innate immunity.

目的观察护理迷你临床演练评估(Nursing-Mini-CEX)结合客观结构化临床考试(OSCE)教学模式在本科急诊护理实习生护理培训中的应用效果。方法选取2023年7—11月郑州大学第一附属医院老院区75名本科急诊护理实习生作为对照组,接受常规教学模式;选取同期东院区75名本科急诊护理实习生作为观察组,接受Nursing-Mini-CEX结合OSCE教学模式。观察两组入科、出科时理论及急救技能考核成绩、学习积极主动性(ALS)评分、评判性思维能力测量表(CTDI-CV)、岗位胜任能力。结果出科时,观察组理论知识、操作技能得分均高于对照组(P<0.05);出科时,观察组ALS量表、CTDI-CV量表及岗位胜任能力量表中各项评分均高于对照组(P<0.05)。结论在本科急诊护理带教管理中,Nursing-Mini-CEX结合OSCE教学模式有助于提升实习生出科成绩,增强其学习主动性和评判性思维能力,并可通过多站点的迷你情景模拟演练和评估强化其岗位胜任能力,在临床带教中具有一定应用价值。
