Figure 4:
Cell lineage of an individual
Anabaena
fi lament. (A) The cell lineage analysis representing spatiotemporal profi les
of cell division (branches) and heterocyst differentiation (red) in the bacterial fi lament. The horizontal axis shows time (h)
after nitrogen step-down. (B, C) Magnifi cation of a part of the
Anabaena
cell lineage shown in the blue square in panel A (B)
and the same lineage superimposed with the spatiotemporal dynamics of P
hetR::gfp
signals (C). Arrowheads indicate some
cells showing different
hetR
expression dynamics (D) Micrographs of P
hetR::gfp
expression patterns from the corresponding
part of the bacterial fi lament. (E) Cells that differentiated into heterocysts without cell divisions (numbers 12 and 39). With
