FMV is Fig Mosaic Virus. There is a ton of information to be gathered either here or via Google. Here is a good thread (click) to read, especially posts #18 and #19 - there are at least a half dozen viruses that infect figs, most aren't talked about here, viruses like AFCV-1, AFCV-2 and FBV-1.
So, to answer your question, FMV is unique, I've only heard of one strain of it, but there are others... who knows how AFCV-1, AFCV-2 or FBV-1 present in a fig cutting? Who knows if some of UCD's plant material is so slow to grow because it's infected by multiple viruses? What we are calling FMV could actually be some AFCV-* variant.
Your pictured fig has the signs I associate with FMV: deformed young leaves with light green "mosaic" patterns. Supposedly, FMV can only be distributed by a certain type of mite and not by pruning shears or proximity, but ... who knows? Research in Turkey supposedly confirms this as facts, but there are so few documents out there on it. Who knows if it will infect your other trees. If you're worried about it and the variety isn't important to you, then feel free to burn it or double-bag and trash it. It's your call. However, if you ever find that some of your other trees are infected, you might feel like an idiot for tossing this one, especially if it's rare.
Quick reality check, and part of the reason why Cathy, Jon and myself are probably more in the "it's impossible to have an FMV-free collection" camp: Some trees are heavily affected by FMV. Others may only show a tiny trace on a tiny corner of every 50th leaf, a spot so miniscule you'd never see it...however, the second you add some stress like too much heat or cold, too much or too little water or light and *BAM* all of a sudden all the leaves show symptoms. You just never know. You never know what you've got.
Anyway, despite my beliefs that it's probably not possible to be FMV-free in this hobby, I still want to respect others and forewarn them about fig infections.
My main gripe is with RKN much more so than FMV. I'll never buy a fig tree from another nursery again because of my experience. This is why I say, "if i knew then what i know now", because if I had the knowledge back then that i have now, I would have never, ever, ever in a million years bought a plant from any nursery, regardless of how reputable it may be. I would have been patient, stuck with cuttings and grown all of my trees that way. At least then, if I ended up with RKN, I could know it was something else, other than where I know the vast majority of RKN around my home came from. Hell, I got one tree a couple years ago that came with live mealybugs on it!! And they were huge!! Two days after finding out what it was, I saw the person I bought the tree from post a picture of a tree from their collection that was covered in them. The picture disappeared after I pointed it out. It just goes to show you ...
