| 1 | The threshold effect of the urban-rural income disparity on real economic growth in China显示文摘鉴于我国的城乡二元结构,本文使用泰尔指数度量和刻画我国的城乡收入差距及其变化特征。同时,本文设定了非线性阈值协整模型,以揭示我国改革开放以来城乡收入差距与实际经济增长的长期非线性关系。结果表明,长期非线性闽值关系在泰尔指数为0.100(阈值)处发生机制转移:1978—1991年,我国城乡收入差距对实际增长的长期效应为正;1992—1999年,收入差距对实际增长的效应由正向负平滑转换;1999年后,我国城乡收入差距对实际经济增长产生阻滞作用,且负效应呈逐年增加趋势。 | Wang Shaoping Ouyang Zhigang | 2008 | Social Sciences in China2008，29，3： | 4 |
| 2 | Tectonic affinity of Paleozoic stratigraphic slices along the northern margin in Dabie Orogen,central China: evidence from Pb isotope of rocks显示文摘Metavolcanic and metasedimentary rocks from the Paleozoic tectono-stratigraphic units along the northern margin in the Dabie orogen show that there are two types of Pb isotopic compositions, which have some affined regularity with tectonic subdivision. Compared with the main tectonic units of the Qinling orogen, the Dingyuan Formation should be the part of the South Qinling orogenic belt or the northern margin of the Yangtze craton, characterized by less radiogenic Pb isotopic composition, and the Guishan Formation, Nanwan Formation-Foziling Group and the Carboniferous should be the part of the North Qinling orogenic belt which is extended to the east, characterized by more radiogenic Pb isotopic composition. These facts combined with the distribution of the geological units suggest that the Paleozoic subduction zone between the Yangtze and North China cratons should be located in the north boundary of the Nanwan Formation-Foziling Group or somewhere that is covered by the Nanwan Formation-Foziling Group now. From the Pb isotopic evidence and suggestion presented here, one aspect of the constraint is provided for determining the position of the Triassic collision suture between the two cratons. | XU Qidong, OUYANG Jianping, ZHANG Benren and KUANG Shaoping(1.

| 4 | Non-specific phospholipase C4 hydrolyzes phosphosphingolipids and phosphoglycerolipids and promotes rapeseed growth and yield显示文摘Phosphorus is a major nutrient vital for plant growth and development,with a substantial amount of cellular phosphorus being used for the biosynthesis of membrane phospholipids.Here,we report that NON-SPECIFIC PHOSPHOLIPASE C4(NPC4)in rapeseed(Brassica napus)releases phosphate from phospholipids to promote growth and seed yield,as plants with altered NPC4 levels showed significant changes in seed production under different phosphate conditions.Clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated nuclease 9(Cas9)-mediated knockout of Bna NPC4 led to elevated accumulation of phospholipids and decreased growth,whereas overexpression(OE)of Bna NPC4resulted in lower phospholipid contents and increased plant growth and seed production.We demonstrate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in vitro,and plants with altered Bna NPC4 function displayed changes in their sphingolipid and glycerolipid contents in roots,with a greater change in glycerolipids than sphingolipids in leaves,particularly under phosphate deficiency conditions.In addition,Bna NPC4-OE plants led to the upregulation of genes involved in lipid metabolism,phosphate release,and phosphate transport and an increase in free inorganic phosphate in leaves.These results indicate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in rapeseed to enhance phosphate release from membrane phospholipids and promote growth and seed production. | Bao Yang Jianwu Li Jiayu Yan Ke Zhang Zhewen Ouyang Yefei Lu Huili Wei Qing Li Xuan Yao Shaoping Lu Yueyun Hong Xuemin Wang Liang Guo | 2023 | Journal of Integrative Plant Biology2023，65，11： | 0 |
