Comparative anatomy and genetic bases of fruit development in selected Rubiaceae (Gentianales)
American Journal of Botany, Volume 108, Issue 10, Page 1838-1860, October 2021., 2021 Abstract Premise The Rubiaceae are ideal for studying the diversity of fruits that develop from flowers with inferior ovary. We aimed to identify morpho‐anatomical changes during fruit development that distinguish those derived from the carpel versus the extra‐carpellary tissues.

American Journal of Botany, Volume 108, Issue 7, Page 1217-1233, July 2021., 2021 Premise Speciation not associated with morphological shifts is challenging to detect unless molecular data are employed. Using Sanger‐sequencing approaches, the Lomatium packardiae/L. anomalum subcomplex within the larger Lomatium triternatum complex could not be resolved. Therefore, we attempt to resolve these boundaries here.

Reconstructing Dipsacales phylogeny using Angiosperms353: issues and insights
American Journal of Botany, Volume 108, Issue 7, Page 1122-1142, July 2021., 2021 Premise Phylogenetic relationships within major angiosperm clades are increasingly well resolved, but largely informed by plastid data. Areas of poor resolution persist within the Dipsacales, including placement of Heptacodium and Zabelia, and relationships within the Caprifolieae and Linnaeeae, hindering our interpretation of morphological evolution ...

New Phytologist, Volume 230, Issue 6, Page 2154-2163, June 2021., 2021 Summary The encapsulation of seeds in hard coats and fruit walls (pericarp layers) fulfils protective and dispersal functions in many plant families. In angiosperms, packaging structures possess a remarkable range of different morphologies and functionalities, as illustrated by thermo and hygro‐responsive seed pods and appendages, as well as ...
