Fig 4. Colocalisation analysis of FD and AREB3 in the SAM.

pAREB3:VENUS:AREB3 areb3-1 and pFD:mCHERRY:FD fd-3 plants were crossed and the F1 progeny was analysed by confocal microscopy. Dissected apices were sampled at 11, 13, 15 and 18 long days (LD) and simultaneously imaged for VENUS, mCHERRY and Renaissance 2200 fluorescence. FM, floral meristem. Scale bars, 100 μm.
