      abstract     = {Both non-equilibrium (in electric-field and shear flow)
                      [1-3] and equilibrium phase behaviour [4-7] are presented
                      for the concentrated suspensions of charged DNA-viruses at
                      the low ionic strength of Tris/HCl buffer. The system is
                      revealed as a good model system of charged colloidal rods
                      (DNA-rods) to predict the phase transitions, from the
                      nematic-to-chiral nematic and other hierarchical
                      chiral-mesophases (X-pattern and helical domains) to the
                      (structural) glass states, in an increase of the
                      rod-concentration [4-6]. In last 2 decades, several
                      instrumentations and methods are developed with
                      characterizations in both signal-and image-processing (under
                      external fields) to access wide ranges of multiple phases
                      and various transitions, dynamics, and kinetics of the
                      interacting charged DNA-rods.Recently, as one of interesting
                      findings for chiral-mesophases, the long-time existing
                      X-pattern is turned out to be the subclass of
                      “chiral-glass”, shown by the replica symmetry breaking
                      (RSB), determined by both real- and Fourier-space [6]. This
                      X-pattern occurs interestingly between the two
                      “replicas” of larger chiral-nematic domain (at a lower
                      concentration) and the “helical-domains” (at a higher
                      concentration) of charged DNA-rods [7]. Further interest is
                      then the order parameter in phase transitions, by
                      dissociation/association of condensed ions in the mean-field
                      approach (via ionic-strength dependent effective Debye
                      screening length and the concentration), as well as the
                      competition between the averaged orientation of concentrated
                      rods and the strength of local ordering of helical domains.
                      The concentration (or the number density) and orientation
                      are coupled via effective diameter in the chiral-mesophase
                      behavior.References[1] K. Kang and J.K.G. Dhont, “An
