Expression of the Arabidopsis floral homeotic gene AGAMOUS is restricted to specific cell types late in flower development.
Mutations in the AGAMOUS (AG) gene cause transformations in two adjacent whorls of the Arabidopsis flower. Petals develop in the third floral whorl rather than the normal stamens, and the cells that would normally develop into the fourth whorl gynoecium behave as if they constituted an ag flower primordium. Early in flower development, AG RNA is evenly distributed throughout third and fourth wh...

متن کاملArabidopsis floral homeotic gene BELL (BEL1) controls ovule development through negative regulation of AGAMOUS gene (AG).
Ovules are the developmental precursors of seeds. In angiosperms the ovules are enclosed within the central floral organs, the carpels. We have identified a homeotic mutation in Arabidopsis, "bell" (bel1), which causes transformation of ovule integuments into carpels. In situ hybridization analysis shows that this mutation leads to increased expression of the carpel-determining homeotic gene AG...
متن کاملThe homeotic protein AGAMOUS controls late stamen development by regulating a jasmonate biosynthetic gene in Arabidopsis.
The Arabidopsis thaliana floral homeotic gene AGAMOUS (AG) plays a central role in reproductive organ (stamen and carpel) development. AG RNA is expressed in the center of floral primordia from a time prior to the initiation of stamen and carpel primordia until late in flower development. While early AG expression acts in specification of stamens and carpels, the role, if any, of continued AG e...
متن کاملRegulation of Late-Stage Flower Development by Downstream Genes of the Homeotic Protein AGAMOUS
The genes and pathways AG regulates in late-stage flower development are largely unknown. Several putative downstream genes of AG involved in anther dehiscence were identified, including DAD1, MYB26, OPR3, COI1, and RBR1, through a bioinformatics approach. A 35S::AG-GR inducible line was constructed for timed-induction expression analysis of anther dehiscence versus indehiscence, which revealed...
