Figure 2. NRIP1 localization is p50-dependent.

(A) In NRIP1-Cerulean transgenic plants, NRIP1-Cerulean colocalized with the red autofluorescence of chloroplasts. NRIP1-Cerulean was found in stromules (arrows). Scale bar is 20 μm.
(B) NRIP1-Cerulean localized to the chloroplasts in wild-type NRIP1-Cerulean (column 1) and N-containing NRIP1-Cerulean (Column 2) transgenic plants expressing TAP alone. NRIP1-Cerulean redistributed to chloroplasts, cytoplasm, and nucleus in the presence of p50-TAP in NRIP1-Cerulean transgenic plants without N (column 3) and with N (column 4). Red structures are chloroplasts. Yellow arrows mark stromules. Scale bars equal 20 μm.
