Using Spinning Disk Microscopy to Observe the Mitotic and Cytokinetic Apparatus in Physcomitrium patens.

Protonemata of the moss Physcomitrium patens are ideal structures in which to observe cytoskeletal organization and dynamics. Special care is needed to prepare P. patens cultures for high-resolution microscopy. Here, we describe methods for spinning disk microscopy of dividing P. patens cells expressing sGFP-tubulin and H2B-mCherry, including detailed methods for culturing P. patens.
