Abstract: By this invention, methods to produce oleic fatty acids in plant seed oils are provided. The methods of the present invention generally involve the suppression of a host plant cells endogenous &bgr;-ketoacyl-ACP synthase I protein. Also described in the instant invention are the plants, cells and oils obtained therefrom.

Abstract: By this invention, modification of the fatty acid composition of a plant seed may be achieved as a result of the activity of a DNA sequence foreign to the plant species to be modified. In particular, it has been found that a plant oil having a modified fatty acid composition can be obtained upon the expression of genes derived from plants of different species than the host plant, upon the expression of genes derived from bacteria, and from the transcription of anti-sense sequences which are complementary to endogenous genes of the plant host cell. In a preferred embodiment, transcription of the fatty acid modifying foreign DNA sequence is restricted to the developing seed tissues.

Abstract: By this invention, compositions and methods of use of Ricinus communis cDNAs encoding &bgr;-ketoacyl-ACP synthase, are provided. Also of interest are plants, plant parts and plant cells comprising the nucleic acid sequences.

Of special interest are methods and compositions of amino acids and nucleic acid sequences related to biologically active plant desaturases as well as sequences, especially nucleic acid sequences, which are to be used as probes, vectors for transformation or cloning intermediates. Biologically active sequences may be found in a sense or anti-sense orientation as to transcriptional regulatory regions found in various constructs.

Abstract: There is provided hitching apparatus including a mounting means (10) including a base plate portion (11) supporting integrally formed struts (12) to which is fabricated an upper mounting socket (13). The base plate portion (11) is secured to the goose-neck of a vehicle by means of the threaded stud and nut of a conventional tow ball. The mounting socket (13) is adapted to receive the tongue portion (17) of a guide assembly including a pair of guide plates (21) which in use diverge from their mounting portion (20) to extend rearward and outward of the tow-ball. Reversing the vehicle to the hitch of the trailer with the hitching assembly installed results in either the hitch directly contacting the mounting portion (20) or engagement of the hitching portion with either of the guide plates (21) whereupon the hitching portion is guided to the mounting portion (20).

Abstract: An axial vane rotary device (14) includes a stator (16) with a cylindrical internal chamber (34) defined an annular outer wall (40) and two side walls (36, 38) of the stator. Each side wall has an annular cam surface (42, 44). A rotor (54) is rotatably mounted within the chamber. The rotor has an annular outer wall (66) and a plurality of angularly spaced-apart, axially extending slots (64) extending therethrough. A vane (68) is slidably received in each slot. The vanes reciprocate axially and alternatively expand and compress spaces between adjacent vanes and the cam surfaces as the rotor rotates. The cam surfaces have alternating first portions (92) and second portions (90). The second portions are further from the rotor than the second portions. The first portions of one said cam surface are aligned with second portions of another said cam surface. The slots extend radially outwards on the rotor to the annular outer wall thereof.

Synthase activities are distinguished by the preferential activity towards longer and shorter acyl-ACPs. Protein preparations having preferential activity towards shorter chain length acyl-ACPs are synthase I-type. Synthases having preferential activity towards longer chain length acyl-ACPs are synthase II-type. Of special interest are synthases obtainable from Ricinus communis.

Abstract: A method and assay kit for determining the presence of an enzyme in a sample are provided. A sample suspected of containing the enzyme is applied to an image gel, which may be any conventional material, typically agarose gel. The sample may first be subjected to electrophoresis, or may be detected directly using the present invention. The image gel includes an immobilized phase capable of binding a product of the enzyme but not the substrate. By exposing the enzyme to substrate, and drawing the resulting reaction mixtures through the image gel, only the product is bound in the image gel. The presence of enzyme may then be determined by detecting the product in the image gel. In addition to developing electrophoresis gels, the method of the present invention will find great use in screening a plurality of complex mixtures which have been separated by other conventional techniques.
