Deregulated Gene Expression in mgo1

(A) to (D) An early arising mgo1-4 flower is shown in (B), a later arising flower with stigmatic tissue and ectopic ovules on outer whorl organs in (C), and a terminal mgo1-4 flower in (D).

(E) and (F) Ectopic carpelloid tissue formation (cf. to [C] and [D]) is repressed in ag-1 mgo1-4 (F) plants.

(G) to (M) Expression of pAG:I-GUS (blue) is ectopically activated in random sectors (arrowheads) in mgo1-4 in contrast to the wild type in rosette leaves ([G] and [H]), inflorescences ([I] and [J]), and flowers ([K] and [L]). A revertant sector (arrowhead) is shown in (M).

(N) and (O) Expression of pBP:GUS (blue) is detected in cotyledonary vasculature and at the tips of the rosette leaves of mgo1-4 (N) but not in the wild type (O).

Bars = 2 mm in (A) and (B), 1 mm in (C) and (D), 2 mm in (E) to (J), and 1 mm in (K) to (O).
