Introduction Native endophytic microorganisms in tobacco seeds are closely related to their resistance Ralstonia solanacearum ( R. ) infections. However, the role of native seed core microbiome suppression bacterial wilt disease (BWD) remains underexplored. Methods The characteristics communities both resistant and susceptible varieties were characterized using high-throughput sequencing technology. Results This study found Paenibacillus as a potential microbial antagonist against BWD based...
After continuous cropping for many years, crops are often subject to growth inhibition, which seriously affects their yields.In agricultural production, soil fumigation can effectively alleviate the biological stress on plants. However, relationship between microbial groups that respond changes and plants, as well whether existence makes a beneficial contribution remains unclear. We explored mechanism of promoting plant by affecting microorganisms. The results showed dazomet treatment...
As a critical region regulating air-sea gas exchanges, the polar Southern Ocean has important implications for deglacial atmospheric CO2 rises. However, proxy data evidence is sparse to evaluate respective roles of biological and physical dynamics in affecting past exchanges due longstanding challenges obtaining carbonate materials reconstruct surface conditions this region. Here, we circumvent these by constraining surface-water based on preformed deep-water properties derived from paired...
ABSTRACT A large amount of literature has proved that zodiac year superstition a significant impact on business behaviors such as risk‐taking, investment return, and insurance purchase, but the relationship between psychological state is still limited. This paper draws epidemiological strategies to construct its research strategy, using data from China explore years individual states. Our findings suggest their mental improves when person's family members enter zodiac. empirical regression...
Abstract During the Last Glacial Maximum (LGM; ~20,000 years ago), global ocean sequestered a large amount of carbon lost from atmosphere and terrestrial biosphere. Suppressed CO 2 outgassing Southern Ocean is prevailing explanation for this sequestration. By contrast, North Atlantic Ocean—a major conduit atmospheric transport to interior via overturning circulation—has received much less attention. Here we demonstrate that pump efficiency during LGM was almost doubled relative Holocene....
Abstract The Subantarctic Southern Ocean has long been thought to be an important contributor increases in atmospheric carbon dioxide partial pressure (pCO 2 ) during glacial-interglacial transitions. Extensive studies suggest that a weakened biological pump, process associated with nutrient utilization efficiency, drove up surface-water pCO this region deglaciations. By contrast, regional influences of the solubility mainly linked temperature variations, have largely overlooked. Here, we...
The surface dynamics of thin molten polystyrene films supported by nanoscale periodic silicon line-space gratings were investigated with x-ray photon correlation spectroscopy. Surface over these nanostructures exhibit high directional anisotropy above certain length scales, as compared to flat substrates. A cutoff scale in the perpendicular grooves is observed. This marks a transition from standard over-damped capillary wave behavior suppressed due substrate interactions.
Abstract We have measured B/Ca in four core‐top planktonic foraminiferal species ( Globigerinoides ruber (white), sacculifer (without final sac‐like chamber), Neogloboquadrina dutertrei , and Pulleniatina obliquiloculata ) from three depth transects (the Caribbean Sea, the southwestern Indian Ocean, Ontong Java Plateau) to evaluate effect of dissolution on B/Ca. At each transect, G. (w) (w/o sac) show decreasing with increasing water depth. This decrease is accompanied decreases shell...
Abstract The accuracy of the Mg/Ca paleothermometer is contested over influences secondary environmental parameters such as salinity and pH. Recent calibrations based on compiled sediment trap laboratory culture data suggest moderate from Core tops are best analogues to downcore samples used for paleoceanographic reconstruction with well‐constrained thus can be validate calibrations. Here, we calibrate new core‐top in Globigerinoides ruber (white) Trilobatus sacculifer (without final...
Abstract Processes underlying changes in the oceanic carbon storage during Last Glacial Maximum and subsequent deglaciation are not fully understood. Here, we present a new high‐resolution radiocarbon reconstruction (expressed as δ 14 R) at depth of modern Lower Circumpolar Deep Water from Pacific Sector Southern Ocean. Our record shows R increases Heinrich Stadial 1 Younger Dryas that agree with deep‐to‐shallow transfer old Ocean these two periods. also shows, for first time, clear ∼80‰...
Abstract Valdivia Bank (VB) is a Late Cretaceous oceanic plateau formed by volcanism from the Tristan‐Gough hotspot at Mid‐Atlantic Ridge (MAR). To better understand its origin and evolution, magnetic data were used to generate anomaly grid, which was inverted determine crustal magnetization. The magnetization model reveals quasi‐linear polarity zones crossing following expected MAR paleo‐locations, implying formation seafloor spreading over ∼4 Myr during of anomalies C34n‐C33r....
Abstract The past ∼200 million years of Earth's geomagnetic field behavior have been recorded within oceanic basalts, many which are only accessible via scientific ocean drilling. Obtaining the best possible paleomagnetic measurements from such valuable samples requires an a priori understanding their magnetic mineralogies when choosing most appropriate protocol for stepwise demagnetization experiments (either alternating or thermal). Here, we present quick, and non‐destructive method that...
<title>Abstract</title> Tobacco bacterial wilt is a major limiting factor for tobacco production and development, it more likely to occur under perennial single cropping of tobacco. In recent years, the rotation tobacco-radish has gradually become popular. Therefore, we studied effects years tobacco–radish on occurrence rhizosphere microorganisms.
