Abstract
This unit presents a highly reliable protocol to produce and screen metaphase chromosome spreads from root tip cell suspensions of soybean (Glycine max), or other legumes. The procedures represent soybean-optimized versions of protocols developed for maize. The use of pressurized nitrous oxide to reliably generate metaphase-arrested chromosomes is crucial to overcoming one of the challenges of working with tiny and numerous soybean chromosomes. © 2017 by John Wiley & Sons, Inc.
