    Notes: Abstract  We describe a protocol for Agrobacterium tumefaciens-mediated transformation of hybrid cottonwoods (Populus sections Tacamahaca Spach. and Aigeiros Duby). The protocol has allowed routine transformation of several economically important cottonwood hybrids (Populus trichocarpa Torr. & Gray×P. deltoides Bartr. ex. Marsh. and P. deltoides×P. nigra L.) that were previously difficult to transform. The procedure was applied to 11 different hybrid cottonwood genotypes and one P. deltoides genotype using kanamycin as the selection agent. Additional experiments showed a very strong interaction between auxin preculture and the effectiveness of various cytokinins for induction of shoot organogenesis. The data also demonstrated the superiority of Agrobacterium strain EHA105 over C58 and LBA4404 for T-DNA transfer based on transient assays with a reporter gene.

    Measurements of electron density and plasma current distributions in Tokamak plasma (1982)
    Springer
    International journal of infrared and millimeter waves 3 (1982), S. 263-277 
    Details
    ISSN: 1572-9559
    Keywords: far-infrared polarimeter/interferometer ; electron density and plasma current distributions ; tokamak plasma ; Faraday rotation ; diagnostics for fusion experiments ; hollow dielectric waveguide

    Topics: Physics
    Notes: Abstract A submillimeter-wave, phase-modulated polarimeter/interferometer is used for simultaneous time-dependent measurement of line-averaged electron density and poloidal field-induced Faraday rotation along chords of the plasma column in ISX-B tokamak. Heterodyne detection and hollow dielectric waveguide are utilized to achieve the high sensitivity required for the multichord experiment. A data analysis code has been developed to reconstruct the asymmetric distributions of plasma density. The validity of the code is examined, and the result shows good agreement with density profiles measured by Thomson scattering.
