Evolutionary analyses of TCP genes in Ranunculales
<p><span>TCP transcription factors play a role in a large number of developmental processes and are at the crossroads of numerous hormonal biosynthetic and signaling pathways. The complete repertoire of TCP genes has already been characterized in several plant species, but not in any species of early diverging eudicots. We focused on the order Ranunculales because of its phylogenetic position as sister group to all other eudicots and its important morphological diversity. We characterized the full set of TCP transcripts in <em>Nigella damascena</em> (Ranunculaceae) and found that they are the orthologs of the TCP genes previously identified from the fully sequenced genome of <em>Aquilegia coerulea</em>. Phylogenetic analyses combined with the identification of conserved amino acid motifs </span><span>suggest that six paralogous genes of class I TCP transcription factors were present in the common ancestor of angiosperms</span><span>. We highlight independent duplications in core eudicots and Ranunculales within the class I and class II subfamilies, resulting in different numbers of paralogs within the main subclasses of TCP genes. </span></p>

Genomic insights into adaptation to heterogeneous environments for the ancient relictual Circaeaster agrestis (Circaeasteraceae, Ranunculales)
<p>Investigating the interaction between environmental heterogeneity and local adaptation is critical to understand the evoutionary history of a species, providing the premise for studying the response of organisms to rapid cimate change. However, for most species how exacty the spatial heterogeneity promotes popuation divergence and how genomic variations contribute to adaptive evolution remain poorly understood.</p> <p>We examine the contributions of geographica and environmental variables to population divergence of the relictual, alpine herb <i>Circaeaster agrestis</i>, as wel as genetic basis of local adaptation using RAD-seq and plastome data.</p> <p><span>We detected</span> significant genetic structure with <span>an extraordinary disequilibrium of genetic diversity</span><span> among regions</span>, and signals of isolation-by-distance along with isolation-by-resistance.
