Alternative final steps in berberine biosynthesis in Coptis japonica cell cultures [PDF]

, 1988
In Coptis japonica cell cultures an alternative pathway has been discovered which leads from (S)-tetrahydrocolumbamine via (S)-canadine to berberine. The two enzymes involved have been partially purified.

Acetylcholinesterase and Butyrylcholinesterase Inhibitory Compounds from (Papaveraceae)

Natural Product Communications, 2010
The roots and aerial parts of Chelidonium majus L. were extracted with EtOH and fractionated using CHCl 3 and EtOH. Repeated column chromatography, preparative TLC and crystallization led to the isolation of five isoquinoline alkaloids, stylopine ( 3 ...

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Multiple Glacial Refugia and Complex Postglacial Dynamics of Primula sikkimensis (Primuaceae) in the Heterogeneous Qinghai‐Tibet Plateau

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

GeneMiner2: Accurate and Automated Recovery of Genes From Genome Skimming Data

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT With the growing accessibility of low cost genome skimming, large‐scale recovery of target genes in non‐model species has become feasible, providing strong data for phylogenomic and evolutionary studies. However, existing tools for data assembly including Read2Tree, HybPiper, and GeneMiner still suffer from computational difficulty and ...

Pol‐NIC: An open database on pollen nutrients, imaging, and contaminants

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Pollen is a key component of pollinators' nutrition, yet information on its nutrient composition is largely missing from floral trait datasets. These data paper compiles existing data for 283 plant species and adds new multidimensional analyses of cultivated and wild plants to address major knowledge gaps, along with photos of pollen grain morphology ...
