Missing links: the genetic architecture of flowers [correction of flower] and floral diversification

Trends Plant Sci. 2002 Jan;7(1):22-31; dicussion 31-4. doi: 10.1016/s1360-1385(01)02098-2.


To understand the genetic architecture of floral development, including the origin and subsequent diversification of the flower, data are needed not only for a few model organisms but also for gymnosperms, basal angiosperm lineages and early-diverging eudicots. We must link what is known about derived model plants such as Arabidopsis, snapdragon and maize with other angiosperms. To this end, we suggest a massive evolutionary genomics effort focused on the identification and expression patterns of floral genes and elucidation of their expression patterns in 'missing-link' taxa differing in the arrangement, number and organization of floral parts.
