In this study, 14 wheat cultivars with contrasting yield and N use efficiency （NUE） were used to investigate the agronomic and NUE-related traits, and the N assimilation-associated enzyme activities under low and high N conditions. Under deficient-N, the cultivars with high N uptake efficiency （UpE） and high N utilization efficiency （UtE） exhibited higher plant biomass, yields, and N contents than those with medium and low NUEs. The high UpE cultivars accumulated more N than other NUE type cultivars. Under sufficient-N, the tested cultivars showed similar patterns in biomass, yield, and N content to those under deficient-N, but the varietal variations in above traits were smaller. In addition, the high UpE cultivars displayed much more of root biomass and larger of root length, surface area, and volume than other NUE type cultivars, indicating that the root morphological traits under N deprivation are closely associated with the plant biomass through its improvement of the N acquisition. The high UtE cultivars showed higher activities of nitrate reductase （NR）, nitrite reductase （NIR）, and gluta- mine synthetase （GS） at stages of seediling, heading and filling than other NUE type cultivars under both low and high N conditions. Moreover, the high UpE and UtE cultivars also displayed higher photosynthetic rate under deficient-N than the medium and low NUE cultivars. Together, our results indicated that the tested wheat cultivars possess dramatically genetic variations in biomass, yield, and NUE. The root morphological traits and the N assimilation enzymatic acitivities play critical roles in regulating N accumulation and internal N translocation under the N-starvation stress, respectively. They can be used as morphological and biochemical references for evaluation of UpE and UtE in wheat.

Objective The compound 2,3,7,8-tetrachlorodibenzo-p-dioxin(TCDD), a persistent organic pollutant, is harmful to the nervous system, but its effects on the brain are still unclear. This study aimed to investigate the effects of TCDD on astrocytes proliferation and underlying molecular mechanism. Methods The cell proliferation was measured by EdU-based proliferation assay and PI staining by flow cytometry. Protein expression levels were detected by Western blotting. Immunofluorescence, cytoplasmic and nuclear fractions separation were used to assess the distribution of signal transducer and activator of transcription 3(STAT3). Results C6 cells treated with 10 and 50 nmol/L TCDD for 24 h showed significant promotion of the proliferation of. The exposure to TCDD resulted in the upregulation in the expression levels of phosphorylated protein kinase B(p-Akt), phosphorylated STAT3, and cyclin D1 in a dose-and time-dependent manner. The inhibition of Akt expression with LY294002 or STAT3 expression with AG490 abolished the TCDD-induced cyclin D1 upregulation and cell proliferation. Furthermore, LY294002 suppressed the activation of STAT3. Finally, TCDD promoted the translocation of STAT3 from the cytoplasm to the nucleus, and LY294002 treatment blocked this effect. Conclusion TCDD exposure promotes the proliferation of astrocyte cells via the Akt/STAT3/cyclin D1 pathway, leading to astrogliosis.

脯氨酸羟化酶(prolyl hydroxylase domain2, PHD2)和血管生成素1(angiogenin 1, Ang-1)在动物适应低氧以及血管生成等方面起着重要作用，为研究PHD2和Ang-1在不同年龄牦牛(Bos mutus)肺脏中的表达分布，探讨其在牦牛肺脏低氧适应性结构形成中的作用。本研究以3日龄、6月龄、3岁和6岁牦牛为研究对象，选取成年黄牛(Bos taurus)为常氧对照，利用免疫组织化学染色(immunohistochemistry, IHC)、组织免疫荧光染色(immunofluorescence, IF)、qRT-PCR、Western blot对PHD2和Ang-1在不同年龄牦牛及黄牛肺脏组织中的表达进行研究。IHC和IF结果显示，PHD2和Ang-1在牦牛和黄牛的表达部位基本相同，主要分布于气管上皮细胞、气管腺、肺动脉内皮细胞和肺泡上皮细胞。qRT-PCR结果显示，PHD2的相对表达量在牦牛组显著高于黄牛组，在3日龄牦牛组显著高于其他年龄组(P<0.01)。Ang-1相对表达量在牦牛组显著高于黄牛组，在6岁牦牛组显著高于其他年龄组(P<0.01)。Western blot结果显示，PHD2蛋白在牦牛组的相对表达量显著高于黄牛组，随着牦牛年龄的增长，PHD2蛋白的相对表达量逐渐降低。Ang-1蛋白在牦牛组的相对表达量显著高于黄牛组，且随着牦牛年龄的增长，Ang-1蛋白的相对表达量逐渐升高。综上所述，PHD2和Ang-1在牦牛肺脏适应高原低氧环境中发挥重要作用，两者主要作用于肺脏上皮细胞和血管内皮细胞，从而维持低氧条件下牦牛肺脏的正常呼吸和肺血管功能的稳定。本研究为进一步探究高原环境下牦牛肺脏低氧适应性机制的研究提供一定的基础资料。

Soil salinity and hydrologic datasets were assembled to analyze the spatio-temporal variability of salinization in Fengqiu County, Henan Province, China, in the alluvial plain of the lower reaches of the Yellow River. The saline soil and groundwater depth data of the county in 1981 were obtained to serve as a historical reference. Electrical conductivity （EC） of 293 surface soil samples taken from 2 kin x 2 km grids in 2007 and 4{） soil profiles acquired in 2（108 was analyzed and used for comparative mapping. Ordinary kriging was applied to predict EC at unobserved locations to derive the horizontal and vertical distribution patterns and variation of soil salinity. Groundwater table data from 22 observation wells in 2008 were collected and used as input for regression kriging to predict the maximum groundwater depth of the county in 2008. Changes in the groundwater level of Fengqiu County in 27 years from 1981 to 2008 was calculated. Two quantitative criteria, the mean error or bias （ME） and the mean squared error （MSE）, were computed to assess the estimation accuracy of the kriging predictions. The results demonstrated that the soil salinity in the upper soil layers decreased dramatically and the taxonomically defined saline soils were present only in a few micro-landscapes after 27 years. Presently, the soils with relatively elevated salt content were mainly distributed in depressions along the Yellow River bed. The reduction in surface soil salinity corresponded to the locations with deepened maximum groundwater depth. It could be concluded that groundwater table recession allowed water to move deeper into the soil profile, transporting salts with it, and thus played an important role in reducing soil salinity in this region. Accumulation of salts in the soil profiles at various depths below the surface indicated that secondary soil salinization would occur when the groundwater was not controlled at a safe depth.
