Abstract: A dispersion of polymer microparticles in organic liquid obtainable by a process comprising the steps of i) providing a mixture comprising a first polymer having functional groups capable of reacting with the carboxylic acid and/or carboxylic acid anhydride groups of a second, polypropylene polymer ii) causing the polymers to melt at a chosen temperature under conditions of high shear, preferably in an extruder, to form an intimate mixture iii) causing the carboxylic acid and/or carboxylic acid anhydride groups of the polypropylene polymer to react with at least some of the functional groups of the first polymer, under conditions of high shear, preferably in an extruder iv) diluting the resulting mixture of step iii) with an organic liquid at a temperature such that a substantially homogeneous solution is formed v) cooling the solution to a temperature whereby the polymer microparticles of the dispersion are formed.

Abstract: The subject application provides polynucleotides, compositions thereof and methods for regulating gene expression in a plant. Polynucleotides disclosed herein comprise novel sequences for a promoter that initiates transcription of an operably linked nucleotide sequence. Thus, various embodiments of the invention comprise the nucleotide sequence of SEQ ID NO: 1 or 2 or fragments thereof that are capable of driving the expression of an operably linked nucleic acid sequence.

Abstract: The subject application provides polynucleotides, compositions thereof and methods for regulating gene expression in a plant. Polynucleotides disclosed herein comprise novel sequences for a promoter isolated from Panicum virgatum (switchgrass) that initiates transcription of an operably linked nucleotide sequence. Thus, various embodiments of the invention comprise the nucleotide sequence of SEQ ID NO: 2 or fragments thereof comprising nucleotides 1 to 692 of SEQ ID NO: 2 that are capable of driving the expression of an operably linked nucleic acid sequence.

Abstract: A dispersion of polymer microparticles in organic liquid, the polymer comprising the reaction product of i) from 2 to 40 parts by weight of a first polymer being polypropylene polymer having sufficient carboxylic acid and/or carboxylic acid anhydride groups equivalent to an acid value of from 2 to 50 mg KOH/g nv polymer and ii) from 60 to 98 parts by weight of a second polymer having a molar excess of functional groups capable of reacting with the carboxylic acid and/or carboxylic acid anhydride groups of the polypropylene polymer and wherein the organic liquid is chosen to be a good solvent for the second polymer and a poor solvent for the polypropylene polymer.
