Use of Protoplasts and Cell Cultures for Physiological and Genetic Studies of Conifers gene transfer, cell fusion, and cloning of selected phenotypes from single cells. The status of research involving conifer protoplasts is reviewed, including analysis of the starting materials, preconditioning procedures, isolation techniques, culture media, and culture systems. Protoplasts and cel

Plantlet Regeneration in vitro via Adventitious Buds and Somatic Embryos in Norway Spruce (,)uds are formed on embryos pulse-treated with cytokinin. A few epidermal and subepidermal cells adjacent to the stomata are stimulated to give rise to meristemoids which subsequently develop further into adventitious buds. Embryogenic callus is formed when the embryos are cultured on medium containin

Analysis of Host Range in Transformation of Higher Plants by ,o plant cells. A wide variety of dicotyledonous plants and some gymnosperms are susceptible to infection. However, the ease of infectability and the efficiency of transformation vary widely within these groups. As a general rule, most of the gymnosperms are infected only with difficulty if at all. T

Inheritance and Evolution of Conifer Organelle Genomestrate the paternal inheritance of chloroplast DNA in Douglas fir and coast redwood and the maternal inheritance of mitochondrial DNA in loblolly pine. Conifers have evolved mechanisms to exclude the maternal transmission of plastids and the paternal transmission of mitochondria. The genetic data fro

Grundbegriffe des Rechnungswesens,s economic importance to the southeastern United States, and has been the subject of intensive tree improvement efforts. The species is amenable to standard cotyledonary micropropagation techniques and to protoplast isolation and culture (as yet only to first-division stage) . Suspension cultures ha
