  • Recovering cryopreserved conifer embryogenic cultures
    Patent number: 6682931
    Abstract: This invention relates to a method for improving the growth and regeneration potential of embryogenic cell and tissue cultures of coniferous plants retrieved from cryopreservation. In particular, this invention relates to the use of abscisic acid in the post-cryopreservation recovery medium to improve both the growth and somatic embryo production of embryogenic cell and tissue cultures of conifers, thereby enabling more rapid proliferation of the embryogenic cultures and a subsequent increase in the yield of somatic embryos. This method is well-suited for employment with a number of biotechnological uses of embryogenic cultures of coniferous plants retrieved from cryopreservation, including use with embryogenic cultures of coniferous plants and with genetically transformed embryogenic cultures of coniferous plants for producing clonal planting stock useful for reforestation.
    Type: Grant
    Filed: May 19, 2000
    Date of Patent: January 27, 2004
    Assignee: MeadWestvaco Corporation
    Inventors: Michael Ryan Becwar, Sharon Anne Krueger
  • Particle-mediated conifer transformation
    Patent number: 6518485
    Abstract: This invention relates to a method for genetically engineering coniferous plants. In particular, this invention relates to a particle-mediated gene transfer method for producing and developing transgenic somatic embryos for plants of the genus Pinus and Pinus interspecies hybrids. This method is well suited for producing transgenic clonal planting stock useful for reforestation.
