摘要：How organs partition themselves into discrete domains with distinct functions is a fundamental question in biology. The gynoecium of flowering plants provides an excellent system to address this question. Here, we show that the boundary between the stigma and style at the gynoecium apex is established by the complementary distribution of the phytohormone auxin and the Auxin Response Factor (ARF), ETTIN (ETT). Mechanistically, auxin induces ETT protein destabilization via the ubiquitin-proteaso...

摘要：Faraday waves, typically observed in driven fluids, result from the confluence of nonlinearity and parametric amplification. Here we show that optical pulses can generate analogous phenomena that persist much longer than the pump time-scales in ordered quantum solids. We present a theory of ultrafast light-matter interactions within a symmetry-broken state; dynamical nonlinear coupling between the Higgs (amplitude) and the Goldstone (phase) modes drives an emergent phason texture that oscillat...

摘要：Mitotic crossovers in diploid organisms are usually detected by looking for loss of heterozygosity (LOH) for a marker. Assuming the crossover occurs between two duplicated chromatids, a single reciprocal crossover will result in two recombinant chromatids and two nonrecombinant chromatids. LOH will only be observed when a recombinant chromatid cosegregates with a nonrecombinant chromatid. Cells containing both recombinant chromosomes will not result in LOH. Below, we use long-range DNA sequenc...

摘要：Kinesin-14 motors are a special class of the kinesin family proteins that walk toward the minus end along the microtubule. It has the reverse directionality compared to the general conventional kinesins. The motility of kinesin-14 has been found to depend on the ionic strength. That is, when the ionic strength changes, the motility of the protein changes significantly. Understanding the origin of such effect is important both as a fundamental problem and as a part of the overall understanding ...

摘要：Chemosymbiosis may have been a key driver of early animal evolution and diversification. Yet evidence for animal-microbe nutritional partnerships in the fossil record of early metazoans remains scarce, largely owing to the limited availability of robust geochemical proxies and suitable fossilization pathways. Here, we report extremely low molybdenum isotope (delta 98Mo) values in pyritized fossils of the terminal Ediacaran Conotubus, a nonbiomineralized cloudinomorph representing some of the e...

摘要：The Yellowstone geo-ecosystem has been the subject of much research, but the ecological history of the Yellowstone Plateau volcanic field and its iconic geyser basins is less known. In this investigation, paleoenvironmental analyses of sediment cores from lakes in Lower Geyser Basin were compared with regional records and paleoclimate model simulations to reconstruct the vegetation, wildfire, limnology, hydrothermal dynamics, and climate drivers since deglaciation, 15,000 to 14,000 years ago. ...

摘要：Distinct behaviors require the nervous system to execute specialized motor programs, each characterized by unique patterns of body muscle coordination. Whether the execution and adaptation of these programs follow conserved principles across species and perturbations remains unclear. To compare motor programs across species, perturbations, and behaviors, we developed the Python toolbox Automated Gait Analysis (AutoGaitA). Using AutoGaitA and inferring from kinematics, we found that locomotor p...

摘要：Plants constantly encounter adverse environmental interactions. One organelle is particularly specialized in stress signaling and phytohormone synthesis: the plastid. Calcium (Ca2+), a key second messenger, is known to intersect with cellular phytohormone signaling networks. While cytosolic Ca2+ dynamics have been studied extensively, the physiological relevance of stromal Ca2+ transients and the identity of channels mediating rapid Ca2+ flux into plastids remain largely unexplored. In this st...
