- Abstract:
In many ways, plants offer unique systems through which to study sex
determination. Because the production of unisexual flowers has evolved
independently in many plant species, different and novel mechanisms may be
operational. Hence, there is probably not one unifying mechanism that
explains sex determination in plants. Advances in our understanding of sex
determination will come from the analysis of the genetics, molecular
biology, and biochemistry of genes controlling sexual determination in
plants. Several excellent model systems for bisexual floral development
(Arabidopsis and Antirrhinum), monoecy (maize), and dioecy (Silene,
asparagus, and mercury) are available for such analyses. The important
questions that remain concern the mechanism of action of sex determination
genes and their interrelationship, if any, with homeotic genes that
determine the sexual identity of floral organ primordia. At the
physiological level, the connection between hormone signaling and
sexuality is not well understood, although significant correlations have
been discovered. Finally, once the genes that regulate these processes are
identified, cloned, and studied, new strategies for the manipulation of
sexuality in plants should be forthcoming. [References: 59]
