We've tried to express some ER markers fused to DsRED (transiently) in 
onion cells. We got cells that expressed the DsRED fusions but all we 
could see were aggregates (inclusion bodies). I haven't tried any other 
markers so far. Actually I have given up on the DsRED. EYFP expresses 
fine both in transient systems as well as in the plant. However, some 
people in the lab complain that the YFP is also more likely to form 
aggregates in lines where the protein is expressed at high levels. I 
haven't had much problems sofar but if you are making stable transgenics 
it shouldn't be a problem since you will get a range of expression 
levels anyway.
Good luck
