Adaptive evolution in the Arabidopsis MADS-box gene family inferred from its complete resolved phylogeny.

Proceedings of the National Academy of Sciences of the United States of America - 11 Nov 2003

Martinez-Castilla León Patricio, Alvarez-Buylla Elena R

Abstract excerpt

Gene duplication is a substrate of evolution. However, the relative importance of positive selection versus relaxation of constraints in the functional divergence of gene copies is still under debate. Plant MADS-box genes encode transcriptional regulators key in various aspects of development and have undergone extensive duplications to form a large family. We recovered 104 MADS sequences from the Arabidopsis...
