Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, Volume 14, Issue 4, July-August 2026.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Airborne Plant eDNA Reflects Local Biodiversity: A Multi‐Method Assessment in a Botanical Garden

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Botanical garden sampling site, three air‐sampling approaches, and three sequencing pipelines (amplicon, short‐, and long‐read shotgun). Results demonstrate strong agreement with known plant sources, high complementarity among methods, and substantial contributions of sub‐pollen particles to airborne plant eDNA.

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.

A Golgi‐localized N‐methyltransferase and reversible aldo–keto reductases coordinate dual terminal routes in galanthamine biosynthesis

open access: yesThe Plant Journal, Volume 126, Issue 6, June 2026.
Significant Statement This study identifies LaTMT2, a Golgi‐localized N‐methyltransferase, and three reversible aldo–keto reductases (LaAKR1 and LaAKR3) as key enzymes coordinating the dual terminal routes of galanthamine biosynthesis in Leucojum aestivum.

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, Volume 68, Issue S2, Page S47-S68, May 2026.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...
