- Abstract:
Arabidopsis flowers develop from groups of undifferentiated cells on the
flank of an inflorescence meristem. The cells in these flower primordia
must somehow assess their position within the primordium and differentiate
accordingly to produce a flower with a precisely defined pattern of organ
types and positions. The molecular mechanisms by which this is
accomplished are largely unknown. We are studying a set of genes whose
mutations give homeotic phenotypes in Arabidopsis flowers. A genetic model
to explain the specification of organ identity by combinatorial action of
the products of these homeotic genes is presented, along with several
aspects that are not readily addressed by the model. The recent cloning of
one of the Arabidopsis homeotic genes, and an additional homeotic gene
from Antirrhinum, has provided an opportunity for molecular tests of our
genetic model. So far, the molecular data are in accord with the genetic
model. [References: 58]
