Abstract:
cDNAs encoding E-null-bisabolelene synthase, null-selinene synthase and null-humulene synthase from Grand Fir (Abies grandis) have been isolated and sequenced, and the corresponding amino acid sequences have been determined. Accordingly, isolated DNA sequences (SEQ ID No:12; SEQ ID No:19 and SEQ ID No:23) are provided which code for the expression of E-null-bisabolene synthase (SEQ ID No:13), null-selinene synthase (SEQ ID No:20) and null-humulene synthase (SEQ ID No:24), respectively, from Grand Fir (Abies grandis). In other aspects, replicable recombinant cloning vehicles are provided which code for E-null-bisabolene synthase, null-selinene synthase and null-humulene synthase, or for a base sequence sufficiently complementary to at least a portion of E-null-bisabolene synthase, null-selinene synthase or null-humulene synthase DNA or RNA to enable hybridization therewith. In yet other aspects, modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding E-null-bisabolene synthase, null-selinene synthase or null-humulene synthase. Thus, systems and methods are provided for the recombinant expression of the aforementioned recombinant sesquiterpene synthases that may be used to facilitate their production, isolation and purification in significant amounts. Recombinant E-null-bisabolene synthase, null-selinene synthase and null-humulene synthase may be used to obtain expression or enhanced expression of E-null-bisabolene synthase, null-selinene synthase and null-humulene synthase in plants in order to enhance the production of sesquiterpenoids, or may be otherwise employed for the regulation or expression of E-null-bisabolene synthase, null-selinene synthase and null-humulene synthase, or the production of their products.
Abstract:
The amino acid and nucleic acid sequences of a Δ5-desaturase enzyme and a Δ8-desaturase enzyme are disclosed. The nucleic acid sequences can be used to design recombinant DNA constructs and vectors. These vectors can then be used to transform various organisms, including for example, plants and yeast. The transformed organisms will then produce polyunsaturated fatty acids. The amino acid sequences are useful for generating enzyme-specific antibodies that are useful for identifying the desaturases.
Abstract:
This disclosure describes a distributed, fault-tolerant security system that enables the secure storage and distribution of private keys. In one implementation, the security system includes a plurality of computing resources that independently store private keys provided by publishers and encrypted using a single security system public key. To protect against malicious activity, the security system private key necessary to decrypt the publication private keys is not stored at any of the computing resources. Rather portions, or shares of the security system private key are stored at each of the computing resources within the security system and multiple security systems must communicate and share partial decryptions in order to decrypt the stored private key.

This invention provides the identification of a truncation polymorphism of the mdr1 gene that is linked to ivermectin sensitivity in subjects, such as collies. Also provided are methods for detecting drug transport sensitivity in a subject, and animal models and in vitro cell systems using cells from animals having an mdr1 truncation.

A cDNA encoding (E)-null-farnesene synthase from peppermint (Mentha piperita) has been isolated and sequenced, and the corresponding amino acid sequence has been determined. Accordingly, an isolated DNA sequence (SEQ ID NO:1) is provided which codes for the expression of (E)-null-farnesene synthase (SEQ ID NO:2), from peppermint (Mentha piperisa). In other aspects, replicable recombinant cloning vehicles are provided which code for (E)-null-farnesene synthase, or for a base sequence sufficiently complementary to at least a portion of (E)-null-farnesene synthase DNA or RNA to enable hybridization therewith. In yet other aspects, modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding (E)-null-farnesene synthase. Thus, systems and methods are provided for the recombinant expression of the aforementioned recombinant (E)-null-famesene synthase that may be used to facilitate its production, isolation and purification in significant amounts. Recombinant (E)-null-farnesene synthase may be used to obtain expression or enhanced expression of (E)-null-famesene synthase in plants in order to enhance the production of (E)-null-farnesene, or may be otherwise employed for the regulation or expression of (E)-null-farnesene synthase, or the production of its product.

Abstract:
A virtual assembly design environment that simulates axial and planar constrained motion for multiple parts in any combination and application order. Dynamic simulation methods are used to simulate object behavior in the design environment using physical laws and collision detection algorithms. The physical properties, e.g., mass properties, of parts in an assembly are created in a separate CAD system. In one embodiment, physical property information is transferred from the CAD system to the virtual reality environment where it is used in dynamic simulations. The parts behave realistically in a user's hand, constrained on the base part, or moving freely in space. A swept volume can be generated directly in the CAD system. Real-time bi-directional data transfer between a VR environment and the CAD system is also provided. As a result, the user can perform parametric design modifications in the virtual environment by the use of a CAD system.
