摘要:Natural variation in metabolism is a key driver of microbial adaptation. While galactose utilization is well studied in budding yeasts, it remains poorly understood in the fission yeast Schizosaccharomyces pombe. Here, we reveal extensive natural variation in galactose utilization across S. pombe isolates-from complete deficiency (Gal-) to exceptionally fast growth (GalF). Gal-strains fall into two classes: one with deletions of the gal gene cluster (via three distinct mechanisms) and another ...

摘要:The mitotic kinase Aurora-A is frequently overexpressed in cancers and contributes to tumor progression and therapy resistance, yet the mechanisms underlying its role in drug resistance remain unclear. Here, we show that sorafenib treatment triggers Aurora-A phase separation, leading to its recruitment into stress granules (SGs), membraneless organelles that promote cancer cell survival. Aurora-A facilitates robust SGs assembly, thereby conferring sorafenib resistance. Mechanistically, upon so...

摘要:Autoimmune nodopathies (AINs) are rare acquired autoimmune neuropathies with distinct clinical features and circulating autoantibodies, often of the immunoglobulin G4 (IgG4) subclass, targeting proteins at the node of Ranvier. Defects in B cell tolerance checkpoints have been implicated in several autoimmune diseases, including MuSK-positive myasthenia gravis, another IgG4 autoantibody-mediated disease. Here, we investigated whether tolerance defects exist in neurofascin-155-mediated AIN (NF15...

摘要:Herein, we present crystal structures of proteins adopting a fold not identified among known /3-solenoids in current structural databases, a Knotted Solenoid. These proteins exhibit a characteristic solenoidal architecture, closely resembling /3-solenoid proteins. However, a unique skip-and-backtrack shift is observed: One coil skips a rotation while the next realigns, distinguishing this fold from previously described solenoids and allowing the formation of a 31 (trefoil) knot. Moreover, the ...

摘要:Many plants, unlike most animals, can reproduce as clones [D. Kester, HortScience 18, 831-837 (1983), 10.21273/hortsci.18.6.831]. Cloning plants is vital to agriculture and biotechnology [H. Barton, T. Denham, Quatern. Int. 489, 17-25 (2018), O. L. Gamborg, In Vitro Cell. Dev. Biol. Plant 38, 84-92 (2002), K.-H. Neumann, A. Kumar, J. Imani, Plant Cell and Tissue Culture-A Tool in Biotechnology: Basics and Application (ed. 2, 2020)], but the extent to which somatic mutation arises during asexua...

摘要:We establish network predictability theory by mapping link prediction onto a spin glass model, where network partitions correspond to spin configurations, and predictability equals the system's average energy. Using the cavity method from statistical physics, we prove that global predictability decomposes into individual link contributions, enabling an efficient local sampling algorithm that reduces the computational complexity of evaluating individual link contributions from being dependent o...

摘要:Rice production underpins food security but relies heavily on nitrogen (N) fertilization, much of which is lost as gaseous emissions. Dinitrogen (N-2) represents the largest N loss, yet its sources remain poorly constrained because biological dinitrogen (N-2) fluxes are difficult to quantify against the atmospheric background. Here, we apply an in situ N-15 tracing-membrane inlet mass spectrometry (N-15-MIMS) technique to simultaneously measure N-2, ammonia (NH3), and nitrous oxide (N2O) emiss...

摘要:Changes to speech offer a quantifiable means to assess speech motor learning, and the resulting memory is thought to be motor in nature. Here, we evaluate this idea and show instead that memory for speech movements has a sensory basis. Speech motor learning, using altered auditory feedback, provides an experimental model to address this question as it involves auditory, somatosensory, and motor components to learning. Transcranial magnetic stimulation was used to disrupt auditory (superior tem...

摘要:Polyadic synapses (where each active zone is juxtaposed with multiple postsynaptic targets) are found in many brain regions and are implicated in learning and memory, yet little is known about how they function. To address this question, we analyze Caenorhabditis elegans cholinergic (ACh) motor neurons, which form dyadic synapses tors in either target elicits a retrograde decrease in presynaptic type 2 voltage-activated calcium channels (CaV2), thereby decreasing ACh release. By contrast, bloc...
