Abstract
One of the key questions in developmental biology is how cell fates are decided. In animal systems, complex signaling systems are often involved in establishing the cellular pattern of tissues. Much less is known about how cellular pattern and cell fates are established in plant systems. Studies have shown that, in general, cell fate is determined by position rather than by lineage (Dawe and Freeling 1991, Irish 1991). This implies that plant cells also signal one another during development to organize the differentiation of various cell types in the appropriate pattern for a given tissue. Recent evidence for the importance of receptor protein kinases in plant development support this (Becraft 1998). The maize aleurone provides an excellent system for studying plant cell fate acquisition; it is a simple system, with only a single cell fate decision between aleurone and starchy endosperm. Also, the genetically controlled anthocyanin pigmentation in the aleurone provides a visible marker that allows convenient screening for mutants disrupted in aleurone formation.
