  • Patent number: 5850022
    Abstract: By this invention, methods to produce C14 fatty acids in plant seed oils are provided. In a first embodiment, this invention relates to particular C14 preferring acyl-ACP thioesterase sequences from Cuphea palustris, camphor and nutmeg, and to DNA constructs for the expression of these thioesterases in host cells for production of C14 fatty acids. Other aspects of this invention relate to methods for using other plant medium-chain thioesterases or medium-chain thioesterases from non-plant sources to provide C14 fatty acids in plant cells. In this regard, the production of C14 fatty acids in plant cells as the result of expression from an elm medium chain acyl-ACP thioesterase and a bacterial luxD gene is provided.

  • Patent number: 5723761
    Abstract: This invention relates to plant thioesterases, specifically plant acyl-ACP thioesterases having substantial activity on palmitoyl-ACP substrates. DNA constructs useful for the expression of a plant palmitoyl-ACP thioesterase in a plant seed cell are described. Such constructs will contain a DNA sequence encoding the plant palmitoyl-ACP thioesterase of interest under the control of regulatory elements capable of preferentially directing the expression of the plant palmitoyl-ACP thioesterase in seed tissue, as compared with other plant tissues, when such a construct is expressed in a transgenic plant. This invention also relates to methods of using a DNA sequence encoding a plant palmitoyl-ACP thioesterase for the modification of the proportion of free fatty acids produced in a plant seed cell. Plant palmitoyl-ACP thioesterase sequences exemplified herein include Cuphea, leek, mango and elm.
