white mutable First two leaves (right)of a mutable wm*-N1802A mutant seedling from a segregating F2 progeny, showing frequent small clonal green revertant sectors; bz2/Ac Ds transposon system.

white mutable wm*-N1834 mutant seedlings grown from pr1 kernels, from a segregating F2 progeny, showing many small clonal green revertant sectors and linkage to pr1 or actual phenotype of pr1* mutant kernel; bz2/Ac Ds transposon system

white mutable A tillered immature wm*-1890 mutant plant, showing distribution of green revertant sectors

white mutable Leaf of wm*-N1890 mutant seedling showing tiny and broad clonal layered green revertant sectors. This mutant displays a bi-modal distribution of revertant events in terms of both size (developemental stage) and intensity of allelic expression.
