    摘要: A culture medium and method for the isolation and culture of plant protoplasts is disclosed which includes in it a quantity of neutral mammalian blood serum. An addition of 1 to 25% serum to protoplast media results in a greater yield of viable protoplast cells, helps to protect the protoplasts in culture, and makes it possiible to obtain and maintain corn protoplasts, a heretofore difficult task.

    摘要: A gas driven apparatus (10) for accelerating particles (16) coated with a genetic material into a target, comprises a reservoir (12) for releasably retaining a gas at a sufficiently high-pressure to detach the particles from the surface of a sample cartridge (14) and to carry the particles through the apparatus (10) toward the target. When leaving the apparatus (10), the particles (16) entrained in the gas stream pass through a substantially conical exit nozzle (24) which causes the pattern of distribution of the particles to greatly expand. Methods for using the apparatus and for preparing the sample cartridges (14) are also described.

    摘要: L'invention concerne une plante productrice de fibres comprenant dans son génome une construction génétique hétérologue. Cette construction génétique comprend un promoteur spécifique aux fibres et une séquence codante sélectionnée à partir du groupe constitué par des séquences codant des gènes producteurs de bioplastiques. De préférence, la séquence codante est sélectionnée à partir du groupe constitué par cétothiolase, réductase de acéto-acétyl-CoA et synthase d'acide poly-bêta-hydroxybutyrique. L'invention concerne également des semences de la plante contenant cette construction génétique, ainsi que des cellules de plantes contenant ladite construction.

    摘要: A method is disclosed for making more efficient the particle-mediated germ line genetic transformation of bean species such as soybean. After a particle-mediated transformation event, in the absence of a selectable marker gene, relatively large numbers of plants must be regenerated to find the relatively low likelihood germ line transformation events which have occurred. It has been discovered that using in the transformation process a marker gene linked to the gene of interest, and by excising a segment of the stem of the shoot during the regeneration process and assaying the sequent for the marker gene, certain patterns or phenotypes can be identified in the stem segment which are associated with an increased frequency of germ line transformation events. As the plants are regenerated, other indices of gene expression, at the first trifoliate leaf stage and at the third or fourth trifoliate leaf stage, also serve as markers of the likelihood of germ line transformation. By using these markers in the relatively early stages of plant regeneration to assay for likelihood of germ line events, it is possible to concentrate regeneration efforts on plants most likely to yield germ line events, and to discard the others, so as to lower the burden and effort in achieving a desired number of transformation events.
