Microtubule arrays function in cellular polarity and morphogenesis
Plant cells vary greatly in shape as a result of cell-type specific patterns of cell expansion. In tip-growing cell projections, such as root hairs of vascular plants or rhizoids of bryophytes, the tubular shape is achieved by restricting growth to the apical domain.
Microtubule arrays are known to control the spatial stability of the apical domain of cell expansion but few microtubule associated proteins have been implicated in this function.
In my research project, I identify and characterize the function of microtubule associated proteins with a new function in tip-growth stability through a combination of forward genetic screens in an emerging haploid plant model, Marchantia polymorpha.
