Arabidopsis homeotic gene APETALA3 ectopic expression: transcriptional and posttranscriptional regulation determine floral organ identity.

Cell - 25 Feb 1994

Jack T, Fox G L, Meyerowitz E M

Abstract excerpt

APETALA3 (AP3) specifies the development of petals and stamens in the Arabidopsis flower. We constructed a transgenic line, 35S-AP3, that ectopically expresses AP3 under the control of a constitutive promoter. The resulting flowers exhibit a replacement of carpels by stamens and resemble flowers...
