Nuclear localization of BeMADS proteins during co-transformation with BeMADS1. Lemmas were used as material for transient transformation by particle bombardment. The tested YFP-BeMADS (numbers in left columns) were co-transformed with BeMADS1-CFP and VirD2-mCherry (nuclear marker). The micrographs in the left column are from Figure 5 and show the localizations of the BeMADS-YFP proteins in B. edulis leaves without co-expression of BeMADS1. Bar = 20 μm.
