    Notes: Abstract A method for long-term plant regeneration of Phaseolus coccineus L, is described. Shoot-tips and cotyledonary nodes cultured on a Murashige and Skoog medium supplemented with N6-benzylaminopurine, 10 μM, and α-naphthaleneacetic acid, 1μM, formed multiple bud-shoots. These shoots were transferred to medium containing BAP 1 μM, NAA 0.1 μM, and gibberellic acid 3 μM to promote shoot growth and further shoot multiplication. Rooting was achieved in medium with 11 μM indole-3-acetic acid. Rooted plants grew to maturity and were fertile. Cultures have maintained their ability to regenerate plants for more than two years. A sample of 30 regenerated plants (R0) was tested for chromosome number, all of them being diploid; seven isozymatic systems were electrophpretically analyzed in 82 R0 regenerated plants. No differences were observed in their electrophoretic patterns in comparison with those shown by seedlings. Histological studies revealed the origin of buds from calluses via organogenesis.

    Colchicine effect on the chromosome number of barley embryos culturedin vitro (1982)
    Springer
    Protoplasma 113 (1982), S. 237-240

    Topics: Biology
    Notes: Summary The effect of colchicine upon the embryos of barley (Hordeum vulgare L.) culturedin vitro has been studied. Different concentrations of the drug as well as different times of culture in its presence have been tested, in order to ascertain the optimal conditions for the induction of non diploid cells. Tetraploid cells were always infrequent after the treatments, reaching the higher values during the first days of culture; aneuploid cells being frequent in some cases.

    Superconductivity-induced features in the electronic Raman spectrum of monolayer graphene (2018)
    American Physical Society (APS)
    Details
    Publication Date: 2018-04-06
    Description: Author(s): A. García-Ruiz, M. Mucha-Kruczyński, and V. I. Fal'ko Using the continuum model, we investigate theoretically the contribution of the low-energy electronic excitations to the Raman spectrum of superconducting monolayer graphene. We consider superconducting phases characterised by an isotropic order parameter in a single valley and find a Raman peak at ... [Phys. Rev. B 97, 155405] Published Thu Apr 05, 2018

Heun Weak localization was observed in a black phosphorus field-effect transistor 65 nm thick. The weak localization behavior was found to be in excellent agreement with the Hikami-Larkin-Nagaoka model for fields up to 1 T, from which characteristic scattering lengths could be inferred. The temperature d… [Phys. Rev. B 94, 245404] Published Fri Dec 02, 2016
