The separation of radionuclides is critical for the sustainable development of nuclear energy. It is urgent to design and prepare functionalized materials for efficient radionuclides separation. Porous materials are considered excellent candidates for the separation of radionuclides under complex conditions due to their high specific surface areas, tunable pore structures and controllable functionalities. In this review, we summarized the design, preparation and functionalization of porous materials and their application for separation of radionuclides in the past five years, discussed the separation performance and analyzed the structure-activity relationship between various radionuclides and porous materials, and systematically clarified their characterization and mechanism of different type porous materials. We also introduced the detection, irradiation and chemical toxicity of different reflective radionuclides.

The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in china and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2.14.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.2.% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package

The influence of the confining potential strength and temperature on the structures and dynamics of a two-dimensional (2.) dusty plasma system is investigated through molecular dynamic (MD) simulation. The circular symmetric confining potential leads to the nonuniform packing of particles, that is, an inner core with a hexagon lattice surrounded by a few outer circular shells. Under the appropriate confining potential and temperature, the particle trajectories on middle shells form a series of concentric and nested hexagons due to tangential movements of *** square displacement, self-diffusion constant, pair correlation function, and the nearest bond are used to characterize the structural and dynamical properties of the system. With the increase of the confining potential, the radial and tangential movements of particles have different behaviors. With the increase of temperature, the radial and tangential motions strengthen, particle trajectories gradually become disordered, and the system gradually changes from a crystal or liquid state to a gas state.

植物根茎过渡区(root-stem transition zone,RSTZ)将根和茎相互连接,其发育形态决定了大豆的地上部株型和抗倒伏潜力。本研究通过EMS诱变获得一个RSTZ弯曲或旋转的大豆突变体M_(rstz),其形态特征能够稳定遗传,是探究大豆茎秆发育规律的特异材料。将该突变体和栽培大豆中黄13杂交构建重组自交系群体,对群体中直立和弯曲型后代的RSTZ进行解剖结构比较,发现弯曲型株系比直立型株系的维管形成层较宽、次生木质部细胞层数较多、细胞形状不规则,表明维管组织分化可能是导致RSTZ形态发生差异的重要因素之一。进一步对化学组分测定发现,木质素和粗纤维含量越高越不易弯曲。选取RIL群体中弯曲型和直立型2.极端株系进行BSA-Seq,采用SNP-index和InDel-index关联分析方法鉴定到调控RSTZ形态的关联区域Chr19:43030943~45849854,该区间共含有319个基因。结合生物信息学分析、基因注释信息和表达丰度分析筛选到7个候选基因,分别为Glyma.19G1702.0、Glyma.19G2.1500、Glyma.19G187800、Glyma.19G1782.0、Glyma.19G197000、Glyma.19G179100、Glyma.19G196900。其中,Glyma.19G187800、Glyma.19G1782.0和Glyma.19G196900在大豆驯化中潜在影响RSTZ形态建成。本研究为解析大豆RSTZ组织形成及其遗传基础提供了材料基础,并为挖掘调控大豆茎秆发育基因提供新的见解。

Elevating soil water content(SWC)through irrigation was one of the simple mitigation measures to improve crop resilience to heat *** response of leaf function,such as photosynthetic capacity based on chlorophyll fluorescence during the mitigation,has received limited attention,especially in field conditions.A two-year field experiment with three treatments(control treatment(CK),high-temperature treatment(H),and high-temperature together with elevating SWC treatment(HW))was carried out during grain filling with two maize hybrids at a typical station in North china ***,the net photosynthetic rate(Pn)was improved by 2.%,and the canopy temperature decreased by 1–3℃ in HW compared with in H in both ***,the higher SWC in HW significantly improved the actual photosynthetic rate(Phi2.,linear electron flow(LEF),variable fluorescence(F_(v)),and the maximal potential quantum efficiency(F_(v)/F_(m))for both ***,different responses in chlorophyll fluorescence between hybrids were also *** higher SWC in HW significantly improved thylakoid proton conductivity(g H^(+))and the maximal fluorescence(F_(m))for the hybrid *** the hybrid XY335,the proton conductivity of chloroplast ATP synthase(v H^(+))and the minimal fluorescence(Fo)was increased by the *** structural equation model(SEM)further showed that SWC had significantly positive relationships with Pn,LEF,and F_(v)/F_(m).The elevating SWC alleviated heat stress with the delayed leaf senescence to prolong the effective period of photosynthesis and enhanced leaf photosynthetic capacity by improving Phi2.LEF,Fv,and F_(v)/F_(m).This research demonstrates that elevating SWC through enhancing leaf photosynthesis during grain filling would be an important mitigation strategy for adapting to the warming climate in maize production.
