    • Organisms are provided containing genes encoding one or more enzymes, Coenzyme-A-dependent aldehyde dehydrogenase, acyl-CoA transferase, acyl-CoA synthetase, ß-ketothiolase, acetoacetyl-CoA reductase and/or PHA synthase. In some cases one or more of these genes are native to the host organism and the remainder are heterologous genes provided by genetic engineering. These organisms produce poly (3-hydroxyalkanoate) homopolymers or co-polymers comprising 3-hydroxalkanoate monomers other than 3-hydroxybutryrate wherein these 3-hydroxyalkanoate units are derived from the enzyme-catalyzed conversion of alcohols to 3-hydroxyacyl-CoA monomers, where at least one step in the conversion pathway involves a Co-enzyme A-dependent aldehyde dehydrogenase activity. The PHA polymers are readily recovered and industrially useful as polymers for articles such as films, latexes, coatings, adhesives, fibers, binders, resins, and medical devices.

    • Methods for producing polyhydroxyalkanoates (PHAs) from fatty acid biosynthetic pathways using a 3-hydroxy acyl ACP thioesterase, a PHA synthase, and an acyl CoA synthetase, have been developed. Methodology for enabling PHA production from fatty acid biosynthetic pathways in non-native bacterial PHA producers and plants using an enzyme having the catalytic activity of 3-hydroxy acyl ACP thioesterase, an acyl CoA synthetase with substrate specificity for medium chain length 3-hydroxy fatty acids, and a medium chain length PHA synthase, has been developed. Acyl CoA synthetase activity can be supplied either by the endogenous acyl CoA synthetase of the host organism, when sufficiently expressed, or the host organism's activity can be supplemented by the expression of a recombinant acyl CoA synthetase gene. New strategies are described for plant based PHA production in the chloroplasts, cytosol, and peroxisomes of biomass crops as well as the plastids, cytosol, and peroxisomes of oil seed crops.

    • Methods and constructs for the introduction of multiple genes into plants using a single transformation event are described. Constructs contain a single 5' promoter operably linked to DNA encoding a modified intein splicing unit. The splicing unit is expressed as a polyprotein and consists of a first protein fused to an intein fused to a second protein. The splicing unit has been engineered to promote excision of all non-essential components in the polyprotein but prevent the ligation reactions normally associated with protein splicing. Additional genetic elements encoding inteins and additional proteins can be fused in frame to the 5'-terminus of the coding regions for the second protein to form a construct for expression of more than two proteins. A single 3' termination sequence, such as a polyadenylation sequence when the construct is to be expressed in eucaryotic cells, follows the last coding sequence. These methods and constructs are particularly useful for creating plants with stacked input traits, illustrated by glyphosate tolerant plants producing BT toxin, and/or value added products, illustrated by the production of polyhydroxyalkanoates in plants.
    • 描述了使用单一转化事件将多个基因引入植物的方法和构建体。 构建体包含与编码修饰的内含肽剪接单元的DNA可操作地连接的单个5'启动子。 剪接单元表示为多聚蛋白,由融合至第二蛋白质的内含肽融合的第一个蛋白质组成。 剪接单元已被设计用于促进多蛋白中所有非必需组分的切除,但是防止通常与蛋白质剪接相关的连接反应。 编码内含肽和其他蛋白质的其他遗传元件可以与第二个蛋白质的编码区的5'端融合,形成表达两种以上蛋白质的构建体。 当构建体在真核细胞中表达时,单个3'终止序列,例如聚腺苷酸化序列,遵循最后的编码序列。 这些方法和结构对于产生具有堆叠输入性状的植物特别有用,由产生BT毒素的草甘膦耐受植物和/或增值产物说明,其通过在植物中生产聚羟基链烷酸酯来说明。
