Several Types of Physioligical Response to Different Humidities in Fruits and Vegetables

In this paper,effects of relative humidity(RH)on the respiration rate and ethylene production of 63 kinds of fruits and vegetables including flowres were investigated at diffrent humidities of high RH (93-98%)and low RH(52-65%).From the respiratory response to RH,they could be classified into three groups:accelerative,inhibitive and insensitive low RH.The first group included climacteric fruits such as banana,pear and kiwifruit;the majority of the fruit vegetables;and root vegetables such as tap root,tuber and tuberous root.The second group included Chinese pear,Japanese pear,strawberry,the majority of the leaf vegetables,mushrooms and flowres.The third group included grape and orange.Furthermore,by appending endogenous ethylene production at low RH,they could be classified into eight goups from the physiological response to low RH.These results seem to indicate that water deficit stress at low RH was positively correlated their physiology response in secondary order.青果物の湿度環境改善の基礎資料として、湿度条件（高湿：93～98％RH,低湿：52～65％RH、20℃または25℃）が63種の青果物の呼吸活性およびエチレン生成に及ぼす影響について調査し、その結果に基づいて類型化を行った。1.呼吸活性によって三つの類型に分かれるように思われる。一つは低湿による呼吸活性促進型青果物であり、バナナ、セイヨウナシ、キウイフルーツなどのクライマクテリック型果実、多くの果菜類、根菜類中の直根類、イモ類などはこの型に属するように思われる。次は低湿による呼吸活性抑制型青果物であり、チュゴクナシ、ニホンナシ、イチゴ、大部分の葉菜類、茸類、花卉類はこの型に属するように思われる。もう一つは低湿・高湿にかかわらず呼吸活性に大きな差がない型青果物であり、ブドウやオレンジはこの型属するように思われる。2.エチレン生成を加味して、さらに細分するとエチレン生成促進型、抑制型、差なし型があるように思われる。3.低湿に伴う水分損失が一つのストレスとなって二次的に生理的反応に結びつくことが考えられ、実際流通中の青果物の取扱いはこのような湿度に対する反応も考慮して適切に対応する必要がある

Chandra X-ray Analysis of Galaxy Cluster A168

We present Chandra X-ray observations of galaxy cluster A168 (z=0.045). Two X-ray peaks with a projected distance of 676 kpc are found to be located close to two dominant galaxies, respectively. Both peaks are significantly offset from the peak of the number density distribution of galaxies. This suggests that A168 consists of two subclusters, a northern subcluster (A168N) and a southern subcluster (A168S). Further X-ray imaging analysis reveals that (1) the X-ray isophotes surrounding the two X-ray peaks are heavily distorted, (2) an elongated and ontinuous filament connects the two X-ray peaks. These suggest that strong interactions have occurred between the two subclusters. Spectral analysis shows that A168 has a mean temperature of 2.53 +/- 0.09 keV and a mean metallicity of 0.31 +/- 0.04 Z_{solar}. The metallicity is roughly a constant across the cluster but the temperature shows some systematic variations. Most X-ray, optical and radio properties of A168 are consistent with it being an off-axis merger several Gyrs after a core passage, although detailed numerical simulations are required to see whether the observed properties, in particular the significant offset between the optical and X-ray centers, can be reproduced in such a scenario.Comment: 17 pages, 7 figures, to be published in ApJ.

Epithelial-to-mesenchymal transition drives a pro-metastatic Golgi compaction process through scaffolding protein PAQR11

Tumor cells gain metastatic capacity through a Golgi phosphoprotein 3-dependent (GOLPH3-dependent) Golgi membrane dispersal process that drives the budding and transport of secretory vesicles. Whether Golgi dispersal underlies the prometastatic vesicular trafficking that is associated with epithelial-to-mesenchymal transition (EMT) remains unclear. Here, we have shown that, rather than causing Golgi dispersal, EMT led to the formation of compact Golgi organelles with improved ribbon linking and cisternal stacking. Ectopic expression of the EMT-activating transcription factor ZEB1 stimulated Golgi compaction and relieved microRNA-mediated repression of the Golgi scaffolding protein PAQR11. Depletion of PAQR11 dispersed Golgi organelles and impaired anterograde vesicle transport to the plasma membrane as well as retrograde vesicle tethering to the Golgi. The N-terminal scaffolding domain of PAQR11 was associated with key regulators of Golgi compaction and vesicle transport in pull-down assays and was required to reconstitute Golgi compaction in PAQR11-deficient tumor cells. Finally, high PAQR11 levels were correlated with EMT and shorter survival in human cancers, and PAQR11 was found to be essential for tumor cell migration and metastasis in EMT-driven lung adenocarcinoma models. We conclude that EMT initiates a PAQR11-mediated Golgi compaction process that drives metastasis

Unimodal productivity-biodiversity relationship along the gradient of multidimensional resources across Chinese grasslands

Resources can affect plant productivity and biodiversity simultaneously and thus are key drivers of their relationships in addition to plant-plant interactions. However, most previous studies only focused on a single resource while neglecting the nature of resource multidimensionality. Here we integrated four essential resources for plant growth into a single metric of resource diversity (RD) to investigate its effects on the productivity-biodiversity relationship (PBR) across Chinese grasslands. Results showed that habitats differing in RD have different PBRs − positive in low-resource habitats, but neutral in medium- and high-resource ones—while collectively, a weak positive PBR was observed. However, when excluding direct effects of RD on productivity and biodiversity, PBR in high-resource habitats became negative, which leads to a unimodal instead of a positive PBR along the RD gradient. By integrating resource effects and changing plant-plant interactions into a unified framework with the RD gradient, our work contributes to uncovering underlying mechanisms for inconsistent PBRs at large scales

The GEOTRACES Intermediate Data Product 2014

The GEOTRACES Intermediate Data Product 2014 (IDP2014) is the first publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2013. It consists of two parts: (1) a compilation of digital data for more than 200 trace elements and isotopes (TEIs) as well as classical hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing a strongly inter-linked on-line atlas including more than 300 section plots and 90 animated 3D scenes. The IDP2014 covers the Atlantic, Arctic, and Indian oceans, exhibiting highest data density in the Atlantic. The TEI data in the IDP2014 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at cross-over stations. The digital data are provided in several formats, including ASCII spreadsheet, Excel spreadsheet, netCDF, and Ocean Data View collection. In addition to the actual data values the IDP2014 also contains data quality flags and 1-? data error values where available. Quality flags and error values are useful for data filtering. Metadata about data originators, analytical methods and original publications related to the data are linked to the data in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes. The basin-wide 3D scenes allow for viewing of data from many cruises at the same time, thereby providing quick overviews of large-scale tracer distributions. In addition, the 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes, as well as for making inferences about controlling processes

Petrological characteristics of the sedimentary volcaniclastic rocks of the Fossil Hill Formation (eocene) in King George Island, West Antarctica

The Fossil Hill Formation of the type section composed chiefly of the sedimentary-volcaniclastic breccia and tuffites can be divided into two cycles of sedimentation. The thermal fluid was active in the coarse volcaniclastic deposits of the lower cycle, it led to the formation of laumontite, analcite, albite and regularly hybrid mineral of interlayered chlorite and montmorillonite, which are absent from the upper cycle, and to the transportation and concentration of some of trace elements between the coarser tuffites and the overlying fine tuffite bed at the upper part of this cycle. So-called "rain print" and "mud crack" actually are non-sedimentary originally, they were formed respectively by shedding of the small zeolitized concretions on the bedding plane and tectonic pressed stress. The evidences indicate that the Fossil Hill Formation of the Fossil Hill section was deposited in an intermontane lake affected by both volcanic action and seasonal flood under the condition of warm and moist climate
