Three nuclear localization signals (NLS), including an unusual Mat alpha 2-like NLS from maize (Zea mays) R, were found to compete for binding to plant nuclei. In addition, the authentic yeast Mat alpha 2 NLS, which does not function in mammals, was shown to function in plants in vivo. Our results indicate that plants possess a site at the nuclear pore complex that recognizes the three known classes of NLSs.
