maize mutant phenotypes

virescent mutable First two leaves of three v*-N1809 virescent mutant seedlings from a segregating F2 progeny showing variations in greening. From left to right, greening at tip, greening at first leaf and on margin of second leaf, and greening of first leaf and along veins of second leaf. These seedlings have no revertant sectors because the transposon (Ac) is missing.

virescent mutable Leaf chimera, vm*-N1886, showing single large green normal sector revertant due to Ac.

virescent mutable two vm*-N1886 mutant seedlings from a segregating F2 progeny showing greening beginning at first leaf and normal green revertant sector beginning on second leaf; Transposon Ac present.

virescent mutable First two leaves (right) of greenish white vm*-N1807 mutant seedling from an F2 progeny showing many longitudinal revertant green sectors; produced by insertion of a transposon of the bz2/Ac Ds system into an as yet unidentified v locus.

virescent mutable Two vm*-N1806 mutant seedlings from F2 progeny showing, on left, greenish white seedling with longitudinal green sectors, and on right, stable greenish white seedling that is greening up on tip of first leaf. Ac Ds transposon system.

virescent mutable Pale green vm*-N1809 seedling showing greening in pale green crossbands with tiny spots of darker green tissue and diurnal whitish crossbands; indicating that the transposon activator (Ac) is present.
