Conservation and diversification of gene function in plant development.
The Arabidopsis genome sequence has given us an inventory of the genes needed to specify a flowering plant. Plants are highly diverse in appearance and the mechanisms whereby this diversity has arisen need explanation. A fundamental question is to what extent diversity arises from remodelling of gene function or relocation of gene pathways, rather than from the gain or loss of genes. Similar types of genetic rewiring may be responsible for both intra- and inter-specific differences in developmental processes. Recent advances in the understanding of shoot, flower and leaf development provide insights to this question.
