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

Plant 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.

Transcription factors interact with Arabidopsis UVR8 photoreceptor at distinct sites to COP1 and RUP proteins

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Many responses of plants to UV‐B radiation are mediated by the UVR8 photoreceptor. UVR8 functions by interacting directly with various proteins. In particular, binding of transcription factors to UVR8 modifies their ability to regulate sets of genes involved in specific responses to UV‐B.

Triple florigenic signaling in rice promotes stem elongation via transcriptional de‐repression

The Plant Journal, Volume 127, Issue 2, 2026.
Significance Statement Rice florigenic proteins Hd3a, RFT1, and FT‐L1 coordinate reproductive transition with stem elongation through repression of PINE1 expression, independently of floral MADS box proteins, relieving repression of internode growth. PINE1 represses growth by transcriptionally repressing target genes by interacting with TOPLESS‐related

Cloning and Functional Characterization of Two 4-Coumarate: CoA Ligase Genes from Selaginella moellendorffii

Molecules, 2018
Selaginella is an extant lycopodiophyte genus, which is representative of an ancient lineage of tracheophytes. The important evolutionary status makes it a valuable resource for the study of metabolic evolution in vascular plants. 4-coumarate: CoA ligase

The Biosynthesis and Functions of Flavonoids: Recent Advances From Studies Across Land Plant Diversity

Journal of the Royal Society of New Zealand, Volume 56, Issue 3, June 2026.
Over the last decade there have been significant advances in genome sequencing and model species development for ferns, lycophytes, and the bryophyte lineages—mosses, liverworts, and hornworts. This has facilitated research on the biosynthesis and function of flavonoids in these non‐seed land‐plant lineages.

Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?

TAXON, Volume 75, Issue 3, June 2026.
Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.
