Ancient origin of placental expression in the growth hormone genes of anthropoid primates
(Proceedings of the National Academy of Sciences, 2009)In anthropoid primates, growth hormone (GH) genes have undergone at least 2 independent locus expansions, one in platyrrhines (New World monkeys) and another in catarrhines (Old World monkeys and apes). In catarrhines, the ... -
Combinatorial DNA Rearrangement Facilitates the Origin of New Genes in Ciliates
(Oxford University Press, 2015)Programmed genome rearrangements in the unicellular eukaryote Oxytricha trifallax produce a transcriptionally active somatic nucleus from a copy of its germline nucleus during development. This process eliminates noncoding ... -
Evolution of the Petal and Stamen Developmental Programs: Evidence from Comparative Studies of the Basal Angiosperms
(University of Chicago Press, 2000)Our recently acquired understanding of the ABC program, which controls floral organ identity in model plant species such as <i>Arabidopsis thaliana</i> and <i>Antirrhinum majus</i>, has provided a new set of characters ... -
Floral Symmetry Genes and the Origin and Maintenance of Zygomorphy in a Plant-pollinator Mutualism
(National Academy of Sciences, 2010)The evolution of floral zygomorphy is an important innovation in flowering plants and is thought to arise principally from specialization on various insect pollinators. Floral morphology of neotropical Malpighiaceae is ... -
The MADS-Box Gene Family of the Basal Eudicot and Hybrid Aquilegia coerulea ‘Origami' (Ranunculaceae) 1
(Missouri Botanical Garden Press, 2014)The MADS-box genes form a large family of pan-eukaryotic transcription factors that are involved in various aspects of plant growth and development, particularly reproduction. To understand the extent of their conservation ... -
Similar Genetic Mechanisms Underlie the Parallel Evolution of Floral Phenotypes
(Public Library of Science, 2012)The repeated origin of similar phenotypes is invaluable for studying the underlying genetics of adaptive traits; molecular evidence, however, is lacking for most examples of such similarity. The floral morphology of ... -
Understanding the Genetic Basis of Floral Diversity
(American Institute of Biological Sciences, 2007)The major radiations that punctuate angiosperm evolution are often associated with innovations in floral architecture. The field of plant developmental evolution seeks to understand the generation of this diversity using ...
