Comparative chloroplast genomics and insights into the molecular evolution of Tanaecium (Bignonieae, Bignoniaceae).

Species of Tanaecium (Bignonieae, Bignoniaceae) are lianas distributed in the Neotropics and centered in the Amazon. Members of the genus exhibit exceptionally diverse flower morphology and pollination systems. Here, we sequenced, assembled, and annotated 12 complete and four partial chloroplast genomes representing 15 Tanaecium species and more than 70% of the known diversity in the genus.

Phylogeny of Lantana, Lippia, and related genera (Lantaneae: Verbenaceae).

Premise: Lantana and Lippia (Verbenaceae) are two large Linnean genera whose classification has been based on associated fruit traits: fleshy vs. dry fruits and one vs. two seed-bearing units.

Comparative analyses of Mikania (Asteraceae: Eupatorieae) plastomes and impact of data partitioning and inference methods on phylogenetic relationships.

We assembled new plastomes of 19 species of Mikania and of Ageratina fastigiata, Litothamnus nitidus, and Stevia collina, all belonging to tribe Eupatorieae (Asteraceae). We analyzed the structure and content of the assembled plastomes and used the newly generated sequences to infer phylogenetic relationships and study the effects of different data partitions and inference methods on the topologies. Most phylogenetic studies with plastomes ignore that processes like recombination and biparental inheritance can occur in this organelle, using the whole genome as a single locus.

Extremely low nucleotide diversity among thirty-six new chloroplast genome sequences from (Heliantheae, Asteraceae) and comparative chloroplast genomics analyses with closely related genera.

(Heliantheae, Asteraceae) is a diverse genus in the sunflower family. To date, nearly 200 Asteraceae chloroplast genomes have been sequenced, but the plastomes of remain undescribed. Plastomes in Asteraceae usually show little sequence divergence, consequently, our hypothesis is that species of will be overall conserved.

Comparative Chloroplast Genomics at Low Taxonomic Levels: A Case Study Using (Bignonieae, Bignoniaceae).

Chloroplast (cp) genome organization, gene order, and content have long been considered conserved among land plants. Despite that, the generation of thousands of complete plastomes through next-generation sequencing (NGS) has challenged their conserved nature. In this study, we analyze 11 new complete plastomes of (Bignonieae, Bignoniaceae), a diverse genus of Neotropical lianas, and that of .

Contrasting patterns of diversification between Amazonian and Atlantic forest clades of Neotropical lianas (Amphilophium, Bignonieae) inferred from plastid genomic data.

The mechanisms and processes underlying patterns of species distributions have intrigued ecologists and biogeographers for a long time. The Neotropics is the most species-rich region in the World, representing an excellent model for studying the drivers of diversification. In this study, we used a phylogenomic approach to infer relationships and examine the role of major geological and climatic events in shaping biogeographic patterns within Amphilophium (Bignonieae, Bignoniaceae), a genus of Neotropical lianas.

Development of microsatellites for Verbenoxylum reitzii (Verbenaceae), a tree endemic to the Brazilian Atlantic Forest.

Premise Of The Study: Microsatellite markers were developed for Verbenoxylum reitzii (Verbenaceae), a tree endemic to the Brazilian Atlantic Forest, to investigate their usefulness in population genetic studies. The loci were tested for cross-amplification in the related genera Recordia and Duranta. •

Methods And Results: Eleven polymorphic microsatellite markers were isolated from an enriched library of V.
