...Rebecca S. Lamb; Theresa A. Hill; Queenie K.-G. Tan; Vivian F. Irish The Arabidopsis APETALA3 ( AP3 ) floral homeotic gene is required for specifying petal and stamen identities, and is expressed in a spatially limited domain of cells in the floral meristem that will give rise to these organs. Here...

... the requirements of individual genes in intercellular signaling. Using this strategy, we have shown that the floral homeotic APETALA3 (AP3) gene has distinct roles in regulating intercellular signaling in different tissues. In petals, AP3 acts primarily in a cell-autonomous fashion to regulate cell type...

... and L3 contribute, to different degrees, to the mesophyll and other internal tissues. In order to test the roles of the floral homeotic genes in regulating these patterns of cell proliferation, we carried out similar clonal analyses in apetala3-3 and agamous-1 mutant plants. Our results suggest that cell...

...Theresa A. Hill; Christopher D. Day; Susan C. Zondlo; Andrea G. Thackeray; Vivian F. Irish ABSTRACT The APETALA3 floral homeotic gene is required for petal and stamen development in Arabidopsis. APETALA3 transcripts first detected in a meristematic region that will give rise to the petal and stamen...

...Joline J. Tilly; David W. Allen; Thomas Jack ABSTRACT APETALA3 is a MADS box gene required for normal development of the petals and stamens in the Arabidopsis flower. Studies in yeast, mammals and plants demonstrate that MADS domain transcription factors bind with high affinity to a consensus...

...Beth Allyn Krizek; Elliot M. Meyerowitz ABSTRACT The class B organ identity genes, APETALA3 and PISTILLATA , are required to specify petal and stamen identity in the Arabidopsis flower. We show here that the activities of these two genes are sufficient to specify petals and stamens in flowers...
