Experimentally manipulating fungi with optical tweezers**

A short review of the use of optical tweezers in fungal cell biological research is provided. First, we describe how optical tweezers work. Second, we review how they have been used in various experimental live-cell studies to manipulate intracellular organelles, hyphal growth and branching, and whole cells. Third, we indicate how optically trapped microbeads can be used for the localized delivery of chemicals or mechanical stimulation to cells, as well as permitting measurements of the growth forces generated by germ tubes. Finally, the effects of optical trapping on fungal cell viability and growth are assessed.
