However, if the ancestor of clades
I, II, V, VI, and VIII had a dual role in regulating vegetative and
reproductive transitioning, this function has subsequently been
partitioned through differential sub-functionalization following
both gene duplication and speciation (Figures 2A,B). Furthermore,there is evidence of both neo-functionalization (e.g.,in fruit
ripening and glume architecture) and parallel recruitment (e.g., in
branching) in several different lineages
