Abstract
Live-cell imaging is a powerful tool that allows investigators to directly observe the dynamics of cellular processes. Live imaging has proven particularly useful in studying mitotic and meiotic chromosome segregation, where the assembly of spindles and movement of chromosomes can be quantified in ways not possible with fixed cells. This protocol describes how to image live meiosis in the agriculturally important plant, maize. The creation of fluorescently tagged tubulin allows visualization of maize spindles, and nucleic acid dyestain chromosomes. This protocol describes all steps required for live imaging, including how to grow plants, screen for relevant genotypes, harvest meiotic cells, and collect live movies of meiosis. While this protocol was developed for imaging fluorescently tagged tubulin, it can be easily modified to observe the meiotic dynamics of any fluorescently labeled protein of interest. © 2016 by John Wiley & Sons, Inc.
