Endophytic Consortium With Diverse Gene-Regulating Capabilities of Benzylisoquinoline Alkaloids Biosynthetic Pathway Can Enhance Endogenous Morphine Biosynthesis in Papaver somniferum

open access: yesFrontiers in Microbiology, 2019
Secondary metabolite biosynthesis in medicinal plants is multi-step cascade known to be modulated by associated endophytes. While a single endophyte is not able to upregulate all biosynthetic steps, limiting maximum yield achievement.

Structural Elucidation and Engineering of the (S)‐scoulerine 2‐O‐Methyltransferase Enabling Regioselective Epiberberine Biosynthesis in Coptis chinensis

open access: yesPlant Biotechnology Journal, Volume 24, Issue 7, Page 4528-4545, July 2026.
ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.

The complete chloroplast genome of Papaver setigerum and comparative analyses in Papaveraceae

open access: yesGenetics and Molecular Biology, 2020
Papaver setigerum is an annual herb that is closely related to the opium poppy, P. somniferum. Genetic resources for P. setigerum are scarce. In the present study, we assembled the complete chloroplast (cp) genome of P. setigerum based on genome skimming

Beautiful and Useful: Species Richness and the Ecosystem Services of Allotment Gardens in Berlin, Germany

open access: yesPlant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Intensive agriculture and urbanization have led to habitat degradation and fragmentation, reducing plant diversity and subsequently reducing pollinator abundance and richness. This paper investigates the conservation potential of green infrastructure in allotment gardens, which are a common form of urban land use.
