DESCRIPTION:Speakers: Akiko Nakamasu (Kumamoto University)\nAn endoplasmic
reticulum (ER) is a tubular organelle observed in cells of eukaryote incl
uding the plants and animals. Interacting with flow of actin cytoskeleton\
, the net-like pattern organized by ER in plant cells is continuously movi
ng.\n\n For the understanding of this system\, we constructed a mathematic
al model based on a partial differential equation (PDE). By combining two
spatially distributed structures\, an arbitral periodic pattern by PDE and
an actin mesh dependent perturbation\, we successfully obtained the dynam
ics of the system. \n\nIn this model\, it was found that the filamentous a
ctin distribution was not necessarily needed and static perturbations were
sufficient to move the pattern. Then the pattern periodicities were distu
rbed when the dynamics of system could be observed. Therefore\, we inferre
d that\, though it might seem paradoxical\, the capacity to maintain the o
rder and the symmetry of pattern generate the dynamics.\n\nThis theory is
considered to explain one of the basic elements to generate a dynamic patt
ern\, therefore\, further discussions are needed to define the minimal con
ditions for giving the motility. We will comparative investigate the follo
wing points (1) pattern property effected by the perturbations and (2) dis
tribution manners and types of perturbation. Then the periodicity and the
motilities of pattern will be analyzed quantitatively.\n\nhttps://conferen
