| 1 | Orogenic and Anorogenic Granitoids in the Altay Mountains of Xinjiang and Their Discrimination Criteria显示文摘On the basis of field geological studies of the granotoids in the region, mineralogical, petrological, geochemical(including stable isotope geochemical) and isotopic geochronological investigations were carried out on selected representative granitic bodies of various types. The authors have concluded that, apart from the bodies of the orogenic granitoid series, there also exist intrusions of the anorogenic granitoid series in the region. The intrusives of the two series were formed not only in different ages and tectonic environments, but also were derived from different sources of materials. Moreover, they are associated with different mineralizations, belonging to different minerologenetic series(Cheng et al., 1983). They show distinctly a series of discriminative criteria. The problems under discussion in the present paper are of important theoretical and practical significance in the studies of granites of the orogenic belt, particularly the studies of the genesis and related metallogeny of the granites of the region. | Zou Tianren Institute of Mineral Deposits, Chinese Academy of Geological Sciences, Beijing Chao Huizhi and Wu Baiqing Xinjiang Institute of Geology, Ministry of Metallurgical Industry Urumqi, Xinjiang Jiang Minxi | 1989 | Acta Geologica Sinica(English Edition)1989，63，1： | 14 |
| 2 | Tectonic Units and Their Fundamental Characteristics on the Northern Margin of the Alxa Block显示文摘The northern margin of the Alxa block is the junction of a tectonic units. Four first-order tectonic units are distinguished: 1. the Yagan structural zone characteristic of an immature island arc; 2. the Zhusileng-Hangwula structural zone, which was a passive continental margin in the Early Palaeozoic and was transformed into an active continental margin in the Late Palaeozoic;3. the Shalazha structural zone characteristic of a mature island arc; 4. the Nuru-Langshan structural zone, which was a Proterozoic orogenic belt and later evolved into an extensional transtional crust in the Palaeozoic. The above-mentioned tectonic units differ remarkably in sedimentary formations, magmatic rock associations, metamorphism and geochemistry and are bounded by faults between one another. | Wu Tairan Geology Department, China University of Geosciences, Beijing and He Guoqi Geology Department, Peking University Jiang Minxi | 1993 | Acta Geologica Sinica(English Edition)1993，67，4： | 7 |
| 3 | ESCRT-Ⅲ component OsSNF7.2 modulates leaf rolling by trafficking and endosomal degradation of auxin biosynthetic enzyme OsYUC8 in rice显示文摘The endosomal sorting complex required for transport(ESCRT)is highly conserved in eukaryotic cells and plays an essential role in the biogenesis of multivesicular bodies and cargo degradation to the plant vacuole or lysosomes.Although ESCRT components affect a variety of plant growth and development processes,their impact on leaf development is rarely reported.Here,we found that OsSNF7.2,an ESCRT-Ⅲ component,controls leaf rolling in rice(Oryza sativa).The Ossnf7.2 mutant rolled leaf 17(rl17)has adaxially rolled leaves due to the decreased number and size of the bulliform cells.OsSNF7.2is expressed ubiquitously in all tissues,and its protein is localized in the endosomal compartments.OsSNF7.2 homologs,including OsSNF7,OsSNF7.3,and OsSNF7.4,can physically interact with OsSNF7.2,but their single mutation did not result in leaf rolling.Other ESCRT complex subunits,namely OsVPS20,OsVPS24,and OsBRO1,also interact with OsSNF7.2.Further assays revealed that OsSNF7.2 interacts with OsYUC8 and aids its vacuolar degradation.Both Osyuc8and rl17 Osyuc8 showed rolled leaves,indicating that OsYUC8 and OsSNF7.2 function in the same pathway,conferring leaf development.This study reveals a new biological function for the ESCRT-Ⅲcomponents,and provides new insights into the molecular mechanisms underlying leaf rolling. | Liang Zhou Saihua Chen Maohong Cai Song Cui Yulong Ren Xinyue Zhang Tianzhen Liu Chunlei Zhou Xin Jin Limin Zhang Minxi Wu Shuyi Zhang Zhijun Cheng Xin Zhang Cailin Lei Qibing Lin Xiuping Guo Jie Wang Zhichao Zhao Ling Jiang Shanshan Zhu Jianmin Wan | 2023 | Journal of Integrative Plant Biology2023，65，6： | 1 |
