| 1 | Magma mixing of granites at Lianghe:In-situ zircon analysis for trace elements, U-Pb ages and Hf isotopes显示文摘In this paper, we report an integrated study of trace element, U-Pb age and Hf isotopic composition of zircons from alkali feldspar granites, granodiorites and diorite enclaves in a recently discovered ring complex at Lianghe in western Yunnan, Chi na. The granitoids showed identical U-Pb ages of 127, 115 and 122 Ma, from felsic to mafic, but had different zircon trace el ements and Hf isotopic compositions. Trace element content decreased with a gradual increase in εHf(t) values of ?9.1 to ?5.4, ?4.5 to 0, and 3.6 to 6.2, respectively. Results indicate that changes in zircon trace elements generally correlate with changes in Hf isotope signatures within single samples and among various granitoids. These relationships reflect the mixing of felsic and mafic magmas. Evidence indicates that depleted mantle-derived mafic magma underplating caused ancient crustal melting, and then formed large-scale granites in Lianghe during the Early Cretaceous. These granodiorites were formed mainly by the mix ing of mafic magma and granitic magma. | CONG Feng LIN ShiLiang ZOU GuangFu LI ZaiHui XIE Tao PENG ZhiMin LIANG Ting | 2011 | Science China Earth Sciences2011，54，9： | 26 |

| 3 | Genome-wide association study of callus induction variation to explore the callus formation mechanism of rice显示文摘Rice(Oryza sativa) is one of the most widely cultivated food crops, worldwide. Tissue culture is extensively used in rice breeding and functional genome research. The ability to induce callus determines whether a particular rice variety can be subjected to tissue culture and Agrobacterium-mediated transformation. Over the past two decades, many quantitative trait loci(QTLs)related to callus induction traits have been identified;however, individual genes associated with rice callus induction have not been reported. In this study, we characterized three callus-induction traits in a global collection of 510 rice accessions. A genome-wide association study of the rice population in its entirety as well as subpopulations revealed 21 significant loci located in rice callus induction QTLs. We identified three candidate callus induction genes, namely CRL1, Os BMM1, and Os SET1, which Rese are orthologs of Arabidopsis LBD17/LBD29, BBM, and SWN,respectively, which are known to affect callus formation.Furthermore, we predicted that 14 candidate genes might be involved in rice callus induction and showed that RNA interference(RNAi)-mediated disruption of Os IAA10 inhibited callus formation on tissue culture medium.Embryo growth in the Os IAA10 RNAi line was not inhibited by synthetic auxin(2,4-D) treatment, suggesting that Os IAA10 may perceive auxin and activate the expression of downstream genes, such as CRL1, to induce callus formation. The significant loci and candidate genes identified here may provide insight into the mechanism underlying callus formation in rice. | Zhaoyang Zhang Hu Zhao Wei Li Jiemin Wu Zaihui Zhou Fei Zhou Hao Chen Yongjun Lin | 2019 | Journal of Integrative Plant Biology2019，61，11： | 5 |

| 5 | Sharp Threshold of Global Existence for a Nonlocal Nonlinear Schrdinger System in R^(3)显示文摘In this paper, the authors investigate the sharp threshold of a three-dimensional nonlocal nonlinear Schr¨odinger system. It is a coupled system which provides the mathematical modeling of the spontaneous generation of a magnetic field in a cold plasma under the subsonic limit. The main difficulty of the proof lies in exploring the inner structure of the system due to the fact that the nonlocal effect may bring some hinderance for establishing the conservation quantities of the mass and of the energy, constructing the corresponding variational structure, and deriving the key estimates to gain the expected result. To overcome this, the authors must establish local well-posedness theory, and set up suitable variational structure depending crucially on the inner structure of the system under study, which leads to define proper functionals and a constrained variational problem. By building up two invariant manifolds and then making a priori estimates for these nonlocal terms, the authors figure out a sharp threshold of global existence for the system under consideration. | Zaihui GAN Xin JIANG Jing LI | 2019 | Chinese Annals of Mathematics,Series B2019，40，1： | 0 |
