This study identifies a cytochrome P450 enzyme in Angelica keiskei that determines the skeletal structure of tricyclic coumarins by preferentially forming dihydrofuranocoumarins over unsaturated furanocoumarins.

This study identifies two prenyltransferase genes in Macaranga tanarius that catalyze the biosynthesis of diverse prenylated flavonoids in glandular trichomes.

This study identifies CpPT4, a membrane-bound aromatic O-prenyltransferase involved in auraptene biosynthesis in citrus, and shows its functional and evolutionary significance.

This study identifies recurring daytime and nighttime VOC emission patterns in a cool-temperate oak forest using PTR-ToF-MS and PMF, linking them to physiological and environmental factors.

The paper investigates the molecular evolution of terpene synthase genes in Fagaceae, revealing convergent evolution of isoprene synthase activity in two lineages within subgenus Quercus.

The paper uses CRISPR/Cas9 to edit the LePPO1 gene in Lithospermum erythrorhizon, showing it is involved in shikonin biosynthesis and explains the role of copper in the process.

The paper identifies a new prenyltransferase in Glycyrrhiza glabra that catalyzes diverse flavonoid prenylations, expanding known enzymatic pathways for isoflavonoid biosynthesis.

This study shows that horizontal gene transfer of nicotine catabolism genes in Arthrobacter enables its colonization of tobacco roots, shaping the root microbiota community.

This study uses electron microscopy to show that multivesicular bodies mediate both synthesis and secretion of shikonin derivatives in hairy roots of Lithospermum erythrorhizon.

The paper identifies the IspS gene responsible for isoprene emission in Quercus serrata and shows functional differences in related genes from non-emitting species.

The paper identifies two aromatic O-prenyltransferase genes from distant plant species, showing parallel evolution of UbiA superfamily proteins into O-PTs.
