Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis

open access: yesAmerican Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Species complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species‐based scientific questions,

CRABS CLAW‐independent floral nectary development in Penstemon barbatus

open access: yesAmerican Journal of Botany, Volume 112, Issue 6, June 2025.
Abstract Premise Plants secrete carbohydrate‐rich nectar from specialized floral nectary glands to attract pollinators. Arabidopsis and Petunia (rosid and asterid core eudicots, respectively) share genetic control of nectary development requiring activation of CRABS CLAW by euAGAMOUS and PLENA.

Unique bibenzyl cannabinoids in the liverwort Radula marginata: parallels with Cannabis chemistry

open access: yesNew Phytologist, Volume 246, Issue 6, Page 2666-2682, June 2025.
Summary The potential of cannabinoids to address public health challenges has stimulated exploration into alternative sources and production technologies. Radula marginata, an endemic Aotearoa/New Zealand liverwort, produces the bibenzyl cannabinoid perrottetinene (PET), analogous to Cannabis psychoactive tetrahydrocannabinol (THC).
