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

Summary Flower scent is a crucial determiner in pollinator attraction and a significant horticultural trait in ornamental plants. Orchids, which have long been of interest in evolutionary biology and horticulture, exhibit remarkable diversity in floral scent type and intensity. However, the mechanisms underlying floral scent biosynthesis and regulation

ABSTRACT Establishing depositional environments in ancient mudstone successions from epeiric seas is difficult due to the lack of obvious lithological changes, leaving long, largely undifferentiated mudstone intervals that complicate their correlation to near‐shore environments.
