  摘要：Upon activation, plant nucleotide-binding leucine-rich repeat (NLR) immune receptors are known to assemble into oligomeric resistosomes that insert into the plasma membrane, forming calcium (Ca2+)-permeable channels and triggering immunity. Here, we found that the RPW8-like coiled-coil NLR (CCR-NLR) N requirement gene 1 (NRG1) primarily targets organelles instead of the plasma membrane. Unlike canonical CC-NLRs, activated NRG1 accumulated at the chloroplast envelope and channeled stromal Ca2+ ...

  摘要：Indole is widely present in pharmaceuticals and natural products. In this work, we report an intramolecular skeletal editing reaction of tryptamine derivatives enabled by photoreaction of a pendant amide that simultaneously achieves regioselective single-carbon replacement and substitution at the C2 position of indoles. This strategy facilitates deuteration, alkylation, arylation, and acylation at the indole C2 position while also enabling the incorporation of 13C-labeled carbon into the scaff...

  摘要：How far does peer influence spread through social networks before dissipating? This study investigates the diffusion of smoking behavior in adolescent friendship networks using longitudinal data from two schools (n = 3154 students) in the National Longitudinal Study of Adolescent to Adult Health. Using Stochastic Actor-Oriented Models, we simulate interventions targeting heavy smokers using various strategies (random, in-degree, eigenvector centrality) and coverage (10 to 100%). A new exponent...

  摘要：Using modeling and structural studies, we show that chloride incorporation in formamidinium lead iodide (FAPI) perovskites alters the energetics of both the formation and degradation pathways. We fabricated films with two coadditives [15 mole % FA chloride (FACl) and 0.5 mole % BA(2)PbI(4), where BA is butylammonium)], in which FACl ensures chloride incorporation and both additives collectively create a compressive lattice strain that stabilizes the FAPI black phase and bypasses the formation ...
