Flower Evolution: The Origin and Subsequent Diversification of the Angiosperm Flower
Developmental genetic pathways involved in flower formation in model plants such as Arabidopsis and maize enable us to identify genes, gene families, and gene networks that are involved in the regulation of flower initiation, growth and differentiation. These genes can then function as “candidate genes” and their expression, function, and biochemical interactions can be explored in other lineag...
متن کاملMolecular mechanisms underlying origin and diversification of the angiosperm flower.
BACKGROUND Understanding the mode and mechanisms of the evolution of the angiosperm flower is a long-standing and central problem of evolutionary biology and botany. It has essentially remained unsolved, however. In contrast, considerable progress has recently been made in our understanding of the genetic basis of flower development in some extant model species. The knowledge that accumulated t...
متن کاملTowards Improved Reconstruction of Ancestral Gene Order in Angiosperm Phylogeny
Whole genome doubling (WGD), a frequent occurrence during the evolution of the angiosperms, complicates ancestral gene order reconstruction due to the multiplicity of solutions to the genome halving process. Using the genome of a related species (the outgroup) to guide the halving of a WGD descendant attenuates this problem. We investigate a battery of techniques for further improvement, includ...

متن کاملThe ancestral flower of angiosperms and its early diversification
Recent advances in molecular phylogenetics and a series of important palaeobotanical discoveries have revolutionized our understanding of angiosperm diversification. Yet, the origin and early evolution of their most characteristic feature, the flower, remains poorly understood. In particular, the structure of the ancestral flower of all living angiosperms is still uncertain. Here we report mode...
