Negative regulation of the Arabidopsis homeotic gene AGAMOUS by the APETALA2 product.

Cell - 14 Jun 1991

Drews G N, Bowman J L, Meyerowitz E M

Abstract excerpt

We characterized the distribution of AGAMOUS (AG) RNA during early flower development in Arabidopsis. Mutations in this homeotic gene cause the transformation of stamens to petals in floral whorl 3 and of carpels to another ag flower in floral whorl 4. We found that AG RNA is present in the stamen and carpel primordia but is undetectable in sepal and petal primordia throughout early wild-type flower development,...
