Abstract:
Transgenic plants, plant material, plant cells, and genetic constructs for synthesis of biopolymers, for example polyhydroxyalkanoates (“PHA”) are provided. In one embodiment, the transgenic plants synthesize polyhydroxybutyrate (“PHB”). In one embodiment the transgenic plant encodes siRNA for one or more of the genes encoding enzymes for producing PHA. In a more preferred embodiment, the siRNA expression is under the control of an inducible regulatory element. In another embodiment, the transgenic plant contains transgenes that encode expression enzymes that will degrade the polymer. In a preferred embodiment, the expression of these enzymes is under the control of a germination specific, inducible, or minimal promoter. In another embodiment, the transgenic plant contains transgenes encoding enzymes that increase carbon flow for polymer synthesis. In a preferred embodiment, these transgenes encode enzymes that increase carbon flow in the Calvin Cycle.

Abstract:
The invention relates to chimerical genes that have (i) a DNA sequence coding for a desired product, and (ii) an elongase promoter. The DNA sequence is functionally linked with the promoter to allow expression of the product under the control of the promoter. The invention further relates to vectors, plant cells, plants and plant parts and microorganisms that contain the chimerical gene and to methods for producing such vectors, plant cells, plants and plant parts and microorganisms. The invention also relates to elongase-encoding sequences from and to transgenic plants and microorganisms expressing said sequences.

Filed:

International Classification:
C12P 5/00
C12Q 1/527
C12N 9/88
C12Q 1/527
C12N 9/88
Abstract:
The subject technology generally relates to biosynthesis of styrene. Certain embodiments of the subject technology is based, in part, on the recognition that phenylalanine can be converted to styrene by a two-step pathway of deamination and de-carboxylation, with trans-cinnamic acid (tCA) as the intermediate. Two types of enzymes are directly involved in this process, phenylalanine ammonia lyase (PAL), which converts phenylalanine to tCA, and cinnamic acid decarboxylase, which coverts tCA to styrene. Host cells expressing these two types of enzymes can be cultured in bioreactor to produce styrene from renewable substrates such as glucose.
