Abstract: Novel methods for the expression of non-native genes in flax seeds and the seeds of other plant species are provided. The methods involve the use of seed-specific promoters obtained from flax. Additionally provided are novel flax seed-specific promoters, chimeric nucleic acid constructs comprising novel flax seed-specific promoters, transgenic plant cells, transgenic plants and transgenic plant seeds containing novel flax seed-specific promoters. The promoters and methods are useful, for example, for altering the seed oil and protein composition in flax seed or other plant seeds.

Abstract: A novel cotton variety, designated as FM 960B2R, is disclosed. The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by crossing plants of variety FM 960B2R with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of FM 960B2R and to plants of FM 960B2R reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from FM 960B2R.

The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by crossing plants of variety FM 800B2R with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of FM 800B2R and to plants of FM 800B2R reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from FM 800B2R.

Abstract: Methods and means for efficiently downregulating the expression of any gene of interest in eukaryotic cells and organisms are provided. To this end, the invention provides modified antisense and sense RNA molecules, chimeric genes encoding such modified antisense or sense RNA molecules and eukaryotic organisms such as plants, animals or fungi, yeast or molds, comprising the modified antisense and/or sense RNA molecules or the encoding chimeric genes.

Abstract: Methods and means are provided for reducing the phenotypic expression of a nucleic acid of interest in eukaryotic cells, particularly in plant cells, by providing aberrant, preferably unpolyadenylated, target-specific RNA to the nucleus of the host cell. Preferably, the unpolyadenylated target-specifc RNA is provided by transcription of a chimeric gene comprising a promoter, a DNA region encoding the target-specific RNA, a self-splicing ribozyme and a DNA region involved in 3? end formation and polyadenylation.

Abstract: Monoallyloxyimides, diallyloxyimides and polyallyloxyimides of general Formula I. ##STR1## wherein: X is an integer from 1 to 4 inclusive;R.sup.1, R.sup.2, and R.sup.3 are independently selected from the group comprising hydrogen, alkyl, arylalkyl or halogen; andA is all or part of an aromatic, alicyclic or mixed aromatic/alicyclic ring system optionally substituted with one or more alkyl, alkoxy, alkylthio, aryl, heteroaryl, aryloxy, carboxy, alkylamino, dialkylamino, amino, nitro, cyano, halo or haloalkyl groups.This new class of reactive monomer can be used as co-reactants in themosetting matrix resins. The reactive monomers, either alone or with other comonomers, can give rise to cured resin matrix materials with high thermal stability. Mixed with suitable bismaleimide monomers, they can be cured into useful composites having substantially improved thermal stabilities.

Abstract: The generation of X-radiation occurs when a powder (14,24,38,47,58) is sucted to electro-dispersion in an evacuated chamber. The powder is of a conducting or semiconducting material, and is supported on the lower of two electrodes (10,11; 22,25; 36,39; 44,48; 52,56) in the chamber. When the chamber pressure is about 10.sup.-5 Torr or lower, and a high voltage is applied across the electrodes, part of the powder forms a dispersed particulate cloud in the space between the electrodes. The dispersion of the powder results in the generation of X-radiation which is transmitted through the wall (13) of the chamber or through a window (28,35,45) in the apparatus. Visible light is produced if a phosphor (29) is included in the chamber, and is irradiated by X-rays generated upon dispersion of the powder, or if the powder includes particles of a phosphor.
