CSU1 Colocalizes with COP1 in NBs in the Dark.
Onion peels were cobombarded with equal amounts of the DNA constructs, as indicated, and incubated in darkness for 24 h. Epidermal cells were imaged using the CFP and YFP channels of a confocal microscope. CFP-channel, CFP channel image; YFP-channel, YFP channel image; Merged, merged images of CFP and YFP; Dic, differential interference contrast in light microscope mode. Bars = 20 μm.
