Subcellular localization of OsNPPR3. a-e Transient expression of 35S: OsNPPR3-GFP fusion protein located in the nucleolus of rice protoplasts (a, b) and Nicotiana tabacum protoplasts (c-e). Nucleus marker was used as a nucleus indicator (a-d). Nucleolus marker was used as a nucleolus indicator (e). RPBF (Rice Prolamin Box Binding Factor) and RPL23aB (r-Protein family member) were employed as nucleus-targeted and nucleolus-targeted marker, respectively. Scale bars: 1.6 μm in (a), 5 μm in (b, c), 10 μm in (d, e)
