   Sammanfattning : MADS-box genes are important regulators of reproductive development in seed plants, including both flowering plants and conifers. In this thesis the evolution of the AGAMOUS subfamily of MADS-box genes, and what the ancestral function of this group of genes might have been in the early seed plants about 300 million years ago, was addressed by the discovery of two novel conifer genes, both basal to all previously known AGAMOUS subfamily genes.

3. 2. Understanding evolutionary novelty through female-limited polymorphisms

   Författare :Kalle Tunström; Christopher W. Wheat; Rhonda R. Snook; Patrícia Beldade; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; populationsgenetik; Population Genetics;

   Sammanfattning : Understanding how novel traits evolve is a central question in evolutionary biology. However, unraveling the complex genetic and developmental mechanisms underlying trait innovation can be challenging, especially when the trait evolved a long time ago. LÄS MER
