Functional analysis of FtsZ1-2 in the cytoplasm of Physcomitrella patens (Hedw.) B.S.G

Of the five isoforms of FtsZ in the moss P. patens, FtsZ1-2 is the only one with a transit peptide that targets it to the chloroplast as well as the cytoplasm. To show a function of this protein, various exogenous factors have been tested on knock- out-, over-expression-, and wildtype cell-lines. It could be shown, that the formation of GFP-fluorescent structures is depending on light intensity and Cytokinine concentration. Influences of FtsZ1-2 on branching, cell- length, differentiation and light perception where also tested.
