  • Title: [The spreading of Agrobacterium strains in soft-agar (author's transl)].
    Author: Beiderbeck R, Hohl R.
    Journal: Zentralbl Bakteriol Naturwiss; 1979; 134(5):423-8. PubMed ID: 543348.
    Abstract:
    In a diluted synthetic medium solidified by 0.17% agar populations of Agrobacterium spread with a velocity of 0 to 20 mm/24 hours. This spreading is a consequence of chemotactic movement and cell division. Different bacterial strains spread with a characteristic velocity each. Loss of the TI-plasmid leaves the spreading behaviour unimpaired. It is changed after the introduction of virulence by Kerr transfer or after prolonged culture in D-amino acids.
