By quantifying over 100 Cannabis samples for terpene and cannabinoid content and genotyping them for over 100,000 single nucleotide polymorphisms, this study finds that Cannabis labelling is associated with genetic variants in terpene synthase genes.
Field photographs are essential for research and conservation, but are difficult to access since there is no central database or connection between archives. The 25 leading databases hold only 53% of the plant species of the Americas, illustrating the need for increased work on collecting and standardizing this valuable data.
A prime-editing-library-mediated saturation mutagenesis method is developed and used to substantially expand the herbicide-resistant OsACC1 mutations, showing an advantage over base-editing-mediated mutagenesis in the in planta screening of functional mutations.
Not only is climate change having an impact on invasive plants through changes in ecosystem, atmospheric carbon may be changing the plants themselves. This analysis finds higher concentrations of parthenin at higher levels of CO2, making an invasive weed more toxic.
Despite the perception that plant science focuses on strictly scientific criteria, this analysis finds that there is an aesthetic bias in regards to which plants, based on certain traits, receive more research attention.
Species once considered extinct have now, through improved taxonomic knowledge and collection activities, been restored, with lessons for conservation policies both in Europe and globally.
