  摘要：The 2011 moment magnitude 9.1 Tohoku-oki earthquake is exceptional among great earthquakes for having peak slip of similar to 50 to 70 meters on the shallowest portion of the plate boundary megathrust. Drill cores and geophysical logs from International Ocean Discovery Program Expedition 405 demonstrate that the megathrust preferentially develops at the top or base of the pelagic clay in the sedimentary layers present on the incoming Pacific Plate, where pronounced contrasts in physical proper...

  摘要：Recent studies suggest that microbes inhabit tree bark, yet little is known about their identities, functions, and environmental roles. Here we reveal, through gene-centric and genome-resolved metagenomics, that the bark of eight common Australian tree species hosts abundant and specialized microbial communities. The predominant bacteria are hydrogen-cycling facultative anaerobes adapted to dynamic redox and substrate conditions. Furthermore, bark-associated methanotrophs are abundant and can ...

  摘要：Sex determination underpins genesis of male and female flowers with particularly important implications in plant breeding. Auxin and ethylene regulate femaleness in cucurbits. In this work, we identified an auxin response factor 3 (CsARF3) that plays an essential role in carpel development in cucumber. Deletion of CsARF3 resulted in an androecious phenotype with only male flowers, whereas overexpression of CsARF3 led to an increased number of female flowers. CsARF3 promotes femaleness by direc...

  摘要：Communication at synapses is facilitated by postsynaptic receptors, which convert a chemical signal into an electrical response. For ligand-gated ion channels, agonist binding triggers rapid transitions through intermediate states leading to a transient open-pore conformation, with these transitions shaping the postsynaptic response. In this work, we determine structures of the muscle-type nicotinic acetylcholine receptor in unliganded, mono-liganded, and di-liganded states. Agonist binding to...
