Abstract

The field of Arabidopsis flower development began in the early 1980s with the initial description of several mutants including apetala1, apetala2, and agamous that altered floral organ identity (Koornneef and van der Veen, Theor Appl Genet 58:257–263, 1980; Koornneef et al., J Hered 74:265–272, 1983). By the end of the 1980s, these mutants were receiving more focused attention to determine precisely how they affected flower development (Komaki et al., Development 104:195–203, 1988; Bowman et al., Plant Cell 1:37–52, 1989). In the last quarter century, impressive progress has been made in characterizing the gene products and molecular mechanisms that control the key events in flower development. In this review, we briefly summarize the highlights of work from the past 25 years but focus on advances in the field in the last several years.
