Photobody localization of Arabidopsis phytochrome B (phyB) fused to GFP (PBG) correlates closely with the photoinhibition of hypocotyl elongation. However, the N-terminal half of phyB fused to GFP (NGB) is hypersensitive to light despite its inability to localize to photobodies. Therefore, the significance of photobodies in regulating hypocotyl growth remains ...
