Heading date is a critical trait that determines cropping seasons and regional adaptability in rice （Oryza sativa）. Research efforts during the last decade have identified some important photoperiod pathway genes that are conserved between Arabidopsis and rice. In this study, we identified a novel gene, Oryza sativa ELF3 （OsELF3）, which is a putative homolog of the ELF3 gene in Arabidopsis thaliana. OsELF3 was required for the control of heading date under long-day conditions. Its Tos17-tagging mutants exhibited a delayed heading date phenotype only under long-day, but not short-day, conditions. OsELF3 was highly expressed in leaf blades, and the OsELF3 protein was localized in the nucleolus. An obvious diurnal rhythm of OsELF3 transcript level was observed, with a trough in the early day and a peak in the late night in wild-type plants. However, this expression pattern was disrupted in oself3 mutants. Further inves- tigations showed that the expression of OsGI and Ghd7 was up-regulated in the oself3 mutant, indicating that OsELF3 acts as a negative regulator upstream of OsGI and Ghd7 in the flowering-time control under long-day conditions. The rhythmic expression of circadian clock-related genes, including some OsPRR members, was obviously affected in oself3 mutants. Our results indicated that OsELF3 acts as a floral activator in the long-day photoperiodic pathway via its cross- talk with the circadian clock in rice.

Chelation of 188Re to compounds such as MAG3 will further reduce the radiation dose to the patient in case of balloon rupture through the rapid excretion from the body. In order to prepare highly concentrated, carrier free 188Re-MAG3, Sbenzoyl mercaptoacetyltriglycine (S-Bz-MAG3) was synthesized, labeled with carrier free 188Re. The overall yield of S-Bz-MAG3 is higher than those published in theliterature. Dependence of the labeling yield of 1ssRe-MAG3 upon concentrations of reducing agent, pH, reaction time, etc. was examined and optimum conditions were confirmed. The concentration procedure was succeeded with Sep-Pak C18 cartridge to obtain highly concentrated 1s8Re-MAG3. In the case of optimun conditions, the labeling yield of 188Re-MAG3 was more than 98%. Radiochemical purity of 188ReMAG3 was more than 92% after 24 hour storage at room temperature.

For finding the changes in CO2, H20 exchange and their stomatal regulation during ex vitro acclimatization of regenerated Camptotheca acuminata plantlets, the net photosynthesis rate （Pn）, respiration rate （Ro）, light compensation point （Lc） and light saturation point （Ls）, transpiration rate （Tr）, stomatal conductance （gs） and water use efficiency（WUE） were measured during 37 days of ex vitro acclimatization. The results showed that Pn sharply increased until 29 days, then slightly decreased. A substantial decrease in Lc and a substantial increase of Ls in the former two weeks were observed, indicating the light regime enlargement for effective leaf photosynthesis. Tr and gs abruptly decreased during the first week then linearly increased until 29days ex vitro acclimatization, reflecting the strong regulation effect of stomata on water changes of ex vitro acclimating plantlets. Stomatal regulation effect on CO2 exchange was different from that on water exchange, i.e. P, was almost independent of gs during the first week, while P. was significantly correlated with gs thereafter （i.e. dual patterns）. Different from dual patterns of gs-Pn relation, the Tr monotonously linearly increased with gs. Furthermore, WUE was almost independent on gs during the first week, while a marked decreasing tendency with gs was found thereafter. At the beginning of the acclimatization, WUE was mainly determined by photosynthetic capacity, while transpiration becomes a main determinant factor for WUE from 7 to 37 days＇ acclimatization.

公共服务优先安排需要一种"以服务为重心"的治理体制。当前农村基层治理体制是一种行政型治理体制,主要特点是"重行政、重管理、轻服务",不能很好地适应于公共服务优先安排的国家战略,由此遭遇三大体制挑战:一是从管理型转向服务型体制的挑战,二是从低水平型服务转向高水平型服务的挑战,三是行政型服务转向协作型服务的挑战。公共服务优先安排首先是体制的优先安排与体制的服务性增强。在乡村振兴背景下,为了更好地使当前体制适应于服务优先安排,以服务优先振兴乡村,可以从横向功能、纵向结构两个方面对当前体制进行重组,以建构"重服务,强服务,均衡自治、行政与组织建设"的服务优先安排型治理体制,以服务现代化推进乡村治理体系的现代化。

有效回应民众诉求是政府或官员的重要责任。横村通过设立专门负责回应的“回应员”提高了回应性。“回应员”是以回应责任职能化且专职化为特征的“回应官员”,在便于履行回应职能的组织环境下形成专一化回应模式。专一化回应以专一性的“回应官员”为基础,可以提高回应性,但需要满足责任认知和组织环境两个条件。专一性的回应官员对回应责任的认知度越高、责任内化力越强,组织环境越趋近于协作性组织环境,越容易形成高效的专一化回应。在实践中,回应官员的责任认知和组织环境特征存在差异性和动态性,会生成不同路径的回应行为,进而产生不同程度的专一化回应。基于回应官员的专一化回应,为新时代提升基层政府回应性和乡村善治提供了有效的路径借鉴。

We theoretically investigate the spin resolved Friedel oscillation （FO） and quasiparticle interference （QPI） in graphene induced by an Anderson *** the impurity becomes magnetic,the resulted FO becomes spin dependent,which gives rise to a local magnetic moment oscillation with an envelop decaying as r-2in real space in the doping ***,at half filling,the electron density and local magnetic moment will not oscillate but decay as *** spin resolved FO has both sublattice and spin ***,the local magnetic moment decay at half filling only occurs at one sublattice of graphene,which is quite like the phenomenon observed in the STM experiment (***ález-Herrero et al.,Science 352,437 （2016）).We further give an analytic formula about such spin dependent FO based on the stationary phase ***,we study the interference of quasiparticles around the magnetic impurity by calculating the spin dependent Fourier-transformed local density of states （FT-LDOS）.Our work gives a comprehensive understanding about the local magnetic moment oscillation around an Anderson impurity on graphene.
