Hot node limitations and impact of taxonomic resolution on phylogenetic divergence patterns: A case study on Ecuadorian ethnomedicinal flora

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 644-653, May 2025.
Novel phylogenetic approaches have emerged in recent years to study traditional medicinal plants, aiming to identify potential sources of new drugs. This line of research holds considerable promise yet remains in its early stages. Here, we examine the prevalent methods employed in the field, revealing the impact of methodological choices that have ...

Exploring the genomic diversity and breeding applications of the Solanum sessiliflorum transcriptome via phylogenetic analysis

open access: yesCrop Science, Volume 65, Issue 2, March/April 2025.
Abstract Compelling evidence supports the potential application of wild crop relatives in Solanum breeding. Efforts have been made to generate genomic data from wild Solanum plants to assess the insertion of advantageous traits into crop species. South America hosts a broad range of plants that have not been widely evaluated at the molecular level ...
