Clonal breakdown

This information is from my memory so subject to error. I believe I read
the teliospores shorten everytime a cell divides. After a number of
years they are, in effect, down to the bare bones. It is at this stage
that decreases in vigor and other characteristics are noticeable.

I have read articles on human aging that state that cells can  
duplicate themselves only a certain number of times.  I'm not sure  
what happens when this point is reached:  do they stop?  do they  
accumulate mutations?

Could this limit on cell duplication also be present in plants?
