    • Methods for producing hybrids between domestic and wild soybean that are fertile and can be further bred with other soybean plants are provided, thus allowing transfer of desirable traits and genes from the wild soybean into the domestic soybean. This invention also provides novel media for producing callus and multiple somatic embryos, as well as novel media for producing multiple shoots from the embryos. The hybrid plants are made fertile by colchicine treatment to double their chromosome number so that they can be backcrossed into domestic soybean. These methods and media allow the production of elite soybean lines containing traits or genes from wild soybean as well as a minimum amount of additional wild soybean DNA. Backcrosses containing only one wild soybean chromosome can be produced, as well as sets of such backcrossed lines that each contain one chromosome from the wild ancestor, but collectively all the wild chromosomes from the hybrid ancestor. Plants and plant progeny and plant tissue (tissue including seeds) of plants produced by the foregoing methods are also provided. The methods do not require genetic modification, and thus this invention allows production of domestic soybean plants that are not genetically-modified organisms (non-GMO) but that express desirable traits derived from wild soybean.
    • 提供了能够生育并可与其他大豆植物进一步育种的家庭和野生大豆之间的杂交种的方法,从而使所需的性状和基因从野生大豆转移到国内大豆中。 本发明还提供用于产生愈伤组织和多个体细胞胚的新型培养基,以及用于从胚胎产生多个芽的新型培养基。 通过秋水仙素处理使杂交植物变得肥沃,使其染色体数量增加一倍,使其可以回交到国内大豆中。 这些方法和培养基允许生产含有来自野生大豆的性状或基因的精英大豆品系以及最少量的额外的野生大豆DNA。 可以产生仅含有一个野生大豆染色体的回交,以及各自含有来自野生祖先的一条染色体的这种回交系的集合,但是共同地来自混合祖先的所有野生染色体。 还提供了通过前述方法生产的植物和植物后代和植物组织(包括种子的组织)。 这些方法不需要遗传修饰,因此本发明允许生产不是转基因生物(非转基因)的国内大豆植物,但表达来自野生大豆的理想性状。

    • The present invention provides methods and devices for fabricating 3D structures and patterns of 3D structures on substrate surfaces, including symmetrical and asymmetrical patterns of 3D structures. Methods of the present invention provide a means of fabricating 3D structures having accurately selected physical dimensions, including lateral and vertical dimensions ranging from 10s of nanometers to 1000s of nanometers. In one aspect, methods are provided using a mask element comprising a conformable, elastomeric phase mask capable of establishing conformal contact with a radiation sensitive material undergoing photoprocessing. In another aspect, the temporal and/or spatial coherence of electromagnetic radiation using for photoprocessing is selected to fabricate complex structures having nanoscale features that do not extend entirely through the thickness of the structure fabricated.

    • This invention relates to improved methods for the preparation, purification, and processing of poly(heteroaromatic) block copolymers, as well as compositions prepared by these methods. Methods relate to preparation of multiblock and triblock copolymers of intrinsically conducting polymers (ICPs) containing at least one block of a poly(heteroaromatic) polymer and at least two blocks of a non-conducting polymer. This invention provides polymer solutions or dispersions of improved stability and better film-forming properties. The poly(heteroaromatic) block copolymers are obtained in their conducting or doped form, and are retained in a solvated, wet form throughout the production and purification processes. Stable solutions or dispersions of the purified copolymers in organic solvents, water, or mixtures thereof are provided. Stable solutions or dispersions of ICPs are useful in the preparation of semiconducting and conducting films, blends, and coatings on a variety of substrates using standard processing and coating techniques.

    • Membrane proteins are difficult to express in recombinant form, purify, and characterize, at least in part due to their hydrophobic or partially hydrophobic properties. Membrane scaffold proteins (MSP) assemble with target membrane or other hydrophobic or partially hydrophobic proteins or membrane fragments to form soluble nanoscale particles which preserve their native structure and function; they are improved over liposomes and detergent micelles. In the presence of phospholipid, MSPs form nanoscopic phospholipid bilayer disks, with the MSP stabilizing the particle at the perimeter of the bilayer domain. The particle bilayer structure allows manipulation of incorporated proteins in solution or on solid supports, including for use with such surface-sensitive techniques as scanning probe microscopy or surface plasmon resonance. The nanoscale particles facilitate pharmaceutical and biological research, structure/function correlation, structure determination, bioseparation, and drug discovery.
