张献忠入蜀后,四川的难民潮涌入川西南与川黔交界地带,并与这些边缘地区的“夷民”合流,“夷民”势力随之壮大。孙可望主导的南明政权推行招民垦复与征召“夷兵”之策,鼓动难民开发川西南与川黔交界地带,促使“夷民”离乡出征,军政力量深入西南山区。南明的群体动员与区域开发起到承上启下的作用。吴三桂反叛后,同样征召“夷兵”。在这一历时进程中,抹脸魔传说成为解读明末清初川黔人群流动与民族交融的线索。清朝在统一西南的同时,延续并超越南明经营西南的事业,促进了西南地区的民族交融。抹脸魔传说亦随社会环境的变化而逐渐消散。

The ATP-binding Cassette Transporter OsABCG15 is Required for Anther Development and Pollen Fertility in Rice

引用

Journal of Integrative Plant Biology 2013年第8期55卷 710-720页

Plant male reproductive development is a complex biological process, but the underlying mechanism is not well understood. Here, we characterized a rice （Oryza sativa L.） male sterile mutant. Based on map- based cloning and sequence analysis, we identified a 1,459-bp deletion in an adenosine triphosphate （ATP）-binding cassette （ABC） transporter gene, OsABCG15, causing abnormal anthers and male sterility. Therefore, we named this mutant osabcgl5. Expression analysis showed that OsABCG15 is expressed specifically in developmental anthers from stage 8 （meiosis II stage） to stage 10 （late microspore stage）. Two genes CYP704B2 and WDA1, involved in the biosynthesis of very-long-chain fatty acids for the establishment of the anther cuticle and pollen exine, were downregulated in osabcgl5 mutant, suggesting that OsABCG15 may play a key function in the processes related to sporopollenin biosynthesis or sporopollenin transfer from tapetal cells to anther Iocules. Consistently, histological analysis showed that osabcgl5 mutants developed obvious abnormality in postmeiotic tapetum degeneration, leading to rapid degredation of young microspores. The results suggest that OsABCG15 plays a critical role in exine formation and pollen development, similar to the homologous gene of AtABCG26 in Arabidopsis. This work is helpful to understand the regulatory network in rice anther development.

Electrochemical Study and Application on Shikonin at Poly（diallyldimethylammonium chloride） Functionalized Graphene Sheets Modified Glass Carbon Electrode

引用

Chemical Research in Chinese Universities 2013年第4期29卷 798-805页

作者： AN Jing LI Ji-ping chen Wen-xia YANG Chun-xia HU Fang-di WANG Chun-ming School of Pharmacy Hospital of Lanzhou University College of Chemistry and Chemical Engineering Lanzhou University Lanzhou 730000 P. R. China

The electrochemical behaviors of shikonin at a poly（diallyldimethylammonium chloride） functionalized graphene sheets modified glass carbon electrode（PDDA-GS/GCE） have been investigated. Shikonin could exhibit a pair of well-defined redox peaks at the PDDA-GS/GCE located at 0.681 V（Epa） and 0.662 V（Epc）[vs. saturated calo- mel electrode（SCE）] in 0.1 mol/L phosphate buffer solution（pH=2.0） with a peak-to-peak separation of about 20 mV, revealing a fast electron-transfer process. Moreover, the current response was remarkably increased at PDDA- GS/GCE compared with that at the bare GCE. The electrochemical behaviors of shikonin at the modified electrode were investigated. And the results indicate that the reaction involves the transfer of two electrons, accompanied by two protons and the electrochemical process is a diffusional-controlled electrode process. The electrochemical para- meters of shikonin at the modified electrode, the electron-transfer coefficient（a）, the electron-transfer number（n） and the electrode reaction rate constant（ks） were calculated to be as 0.53, 2.18 and 3.6 s^-1, respectively. Under the optimal conditions, the peak current of differential pulse voltammetry（DPV） increased linearly with the shikonin concentra- tion in a range from 9A72×10^-8 mol/L to 3,789×10^-6 mol/L with a detection limit of 3,157× 10^-8 mol/L. The linear regression equation was Ip=O.7366c＋0.7855（R=0.9978; lp： 10-7 A, c： 10-8 mol/L）. In addition, the modified glass carbon electrode also exhibited good stability, selectivity and acceptable reproducibility that could be used for the sensitive, simple and rapid determination of shikonin in real samples. Therefore, the present work offers a new way to broaden the analytical application of graphene in pharmaceutical analysis.
