John,
        One or two years ago, we got a group of syto dyes for this very purpose, imaging in arabidopsis roots. We were hoping to image DNA along with a GFP reporter and therefore we tested sytos that have long wavelength emission (we were working on confocal, without ability to do uv excitation). None of them worked for us. They tended to be either toxic or dim. The other thing we noticed was that because the cells are crammed with mitochondria that move all over the place, it was difficult to follow nuclear DNA against this hive of mitochondrial motion. But we never tested blue ones.

        Good luck,
                Tobias

Do any of the plant biologists out there have experience using the Syto dyes from Molecular Probes to stain nuclei of living cells.  In particular, they list 5 different dyes in the blue emission range (Syto 40-45).  Syto 42 looks good to me on paper.  What do you think.  Thanks, John.
