  • Patent number: 6117678
    Abstract: The invention concerns measurement of sucrose series oligosaccharides, particularly sucrose, raffinose, and stachyose, and the dehydrin group proteins, in conifer somatic embryos as a measure of their biochemical maturity and readiness to germinate. The information gained is useful for evaluation of the effectiveness of the culture media, particularly that used for the development of the cotyledonary embryo stage. Somatic embryos having elevated levels of the oligosaccharides have been shown to have improved germination, especially those in the genus Pinus. The invention is also directed to conifer somatic embryos having elevated levels of sucrose series oligosaccharides and dehydrin group proteins.

  • Patent number: 5563061
    Abstract: The invention is a method for reproducing coniferous trees by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage proembryos. These are multiplied in a second culture having reduced growth hormones. Maltose is supplied as the carbon and energy source in the second culture. Alternatively, a sucrose-containing maintenance and multiplication medium may be used followed by at least two subcultures on a maltose based maintenance medium. The early stage embryos grow in size and vigor to advanced early stage embryos. The embryos are then transferred to a cotyledonary embryo development culture. After several weeks somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to soil for further growth.

  • Patent number: 5482857
    Abstract: The invention is a method for reproducing Douglas-fir by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage embryos. These are multiplied in a second culture having reduced growth hormones where the early stage embryos grow in size and vigor to advanced early stage embryos. The embryos may then be transferred directly to a cotyledonary embryo development culture containing an adsorbent such as activated charcoal. Preferably, they are first singulated by shaking in two or more liquid subcultures containing the adsorbent prior to placing them on the development medium. After several weeks somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to soil for further growth.

  • Patent number: 5294549
    Abstract: The invention is a method for reproducing coniferous trees by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage proembryos. These are multiplied in a second culture having reduced growth hormones. The early stage embryos may then be placed in or on a late stage proembryo development culture in order to develop very robust late stage proembryos having at least 100 cells. Culturing from this point continues in a cotyledonary embryo development medium containing an active gibberellin (GA) in an amount up to about 50 mg/L. Preferably exogenous abscisic acid (ABA) is also present in a similar amount. Concentration of GA and ABA may be reduced over time by inclusion of an adsorbent such as activated charcoal or by stepwise subcultures in which the later cultures have reduced hormone concentrations.

  • Patent number: 5236841
    Abstract: The invention is a method for reproducing coniferous trees by somatic embryo-genesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage proembryos. These are multiplied in a second culture having reduced growth hormones. The early stage embryos may then be placed in or on a late stage proembryo development culture with a significantly higher osmotic potential than the previous stage or stages in order to develop very robust late stage proembryos having at least 100 cells. Culturing from this point continues in a cotyledonary embryo development medium having a raised osmotic potential. Exogenous abscisic acid is now required at this stage.

  • Patent number: 5041382
    Abstract: The invention lies in the field of conifer tissue culture. It is especially directed to a method for production of large concentrations of embryonal cells particularly suitable for genetic modification. The cells are enriched in the sense that the ratio of embryonal to nonembryogenic cells is very significantly in crased over that attained by earlier methods. The method comprises first developing an embryonalsuspensor mass containing early stage proembryos from a suitable explant. These are multiplied in a maintenance medium and developed to late stage proembryos in a medium that preferably has an osmotic level raised about 30-50% over the initiation medium. The late stage proembryos are transferred to a new medium that again has the osmotic level raised about 35-55% over the proembryo development medium. After three to six transfers a large number of embryonal cells without suspensors will have formed. These may be used in any of the known methods for genetic alteration.

  • Patent number: 5036007
    Abstract: The invention is a method for developing tissue culture induced coniferous somatic proembryos into well developed cotyledonary embryos. The method comprises a multistage culturing process in which early stage proembryos are cultured on a late stage proembryo medium comprising a significantly higher osmotic potential along with abscisic acid and an absorbent material to gradually reduce the level of available abscisic acid over time. Culturing from this point continues in an embryo development medium having a high osmotic potential in which the osmotic potential is preferably raised during embryo development to a final level of about 450 mM/kg. Through this process the vigor and morphology of the embryos is improved and the tendency to germinate prematurely is significantly reduced. After a period of several weeks in culture somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to the soil for further growth.
