    • Compositions and methods for regulating expression of nucleotide sequences of interest in a plant are provided. Compositions include novel nucleic acid molecules, and variants and fragments thereof, for expression control elements isolated from the Lemnaceae ubiquitin, r-histone and chitinase genes. A method for expressing a nucleotide sequence of interest in a plant using the expression control elements disclosed herein is further provided. The method includes introducing into a plant or plant cell or nodule an expression construct comprising an expression control element of the present invention operably linked to a nucleotide sequence of interest. In particular, the compositions and methods find use in enhancing expression of nucleotide sequences of interest in duckweed. Also provided is a novel Lemnaceae signal pepti de-encoding sequence and the signal peptide encoded thereby. Where an expression construct of the invention is designed to express a polypeptide of interest, this novel signal peptide-encoding sequence can be included within the expression construct of the invention to provide for extracellular secretion of the encoded polypeptide of interest.

    • Compositions and methods for producing aglycosylated plasminogen (PLG) polypeptides and fragments and variants thereof are provided. Compositions of the invention include isolated nucleic acid molecules encoding aglycosylated PLG polypeptides in which the asparagine (Asn) residue corresponding to residue Asn-289 of the mature human PLG polypeptide has been substituted with an amino acid residue that does not support N -linked glycosylation at that position of the PLG polypeptide, as well as the aglycosylated PLG polypeptides encoded thereby. Expression constructs comprising these PLG-encoding nucleic acid molecules and transgenic plants comprising these expression constructs are also provided. Methods of the invention comprise introducing a PLG-encoding nucleic acid molecule of the invention into a plant of interest and culturing the plant under conditions to produce the aglycosylated PLG polypeptide. The aglycosylated PLG polypeptide allows for significant increases in production and yield of PLG from a plant-based expression system without comprising the ability of the PLG product to be activated to a polypeptide capable of binding fibrin and having serine protease activity, including biologically active plasmin that is also aglycosylated. The activated aglycosylated plasmin is useful to treat diseases or conditions associated with a thrombus.
    • 提供了用于产生糖基化纤溶酶原(PLG)多肽及其片段和变体的组合物和方法。 本发明的组合物包括分离的编码糖基化PLG多肽的核酸分子,其中对应于成熟人PLG多肽的残基Asn-289的天冬酰胺(Asn)残基已被不支持N-连接糖基化的氨基酸残基取代 PLG多肽的位置,以及由此编码的糖基化的PLG多肽。 还提供了包含编码这些编码PLG的核酸分子和包含这些表达构建体的转基因植物的表达构建体。 本发明的方法包括将本发明的编码PLG的核酸分子引入感兴趣的植物中,并在产生糖苷基化的PLG多肽的条件下培养该植物。 糖基化的PLG多肽允许来自基于植物的表达系统的PLG的产量和产量的显着增加,而不包括PLG产物被活化到能够结合纤维蛋白并具有丝氨酸蛋白酶活性的多肽的能力,包括生物活性纤溶酶, 也糖基化。 活化的糖基化纤溶酶可用于治疗与血栓相关的疾病或病症。
