Opium poppy and Madagascar periwinkle: model non‐model systems to investigate alkaloid biosynthesis in plants [PDF]

The Plant Journal, 2008
SummaryAlkaloids represent a large and diverse group of compounds that are related by the occurrence of a nitrogen atom within a heterocyclic backbone. Unlike other types of secondary metabolites, the various structural categories of alkaloids are unrelated in terms of biosynthesis and evolution.

‘Candidatus Phytoplasma malaysianum’, a novel taxon associated with virescence and phyllody of Madagascar periwinkle (Catharanthus roseus) [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2013
This study addressed the taxonomic position and group classification of a phytoplasma responsible for virescence and phyllody symptoms in naturally diseased Madagascar periwinkle plants in western Malaysia. Unique regions in the 16S rRNA gene from the Malaysian periwinkle virescence (MaPV) phytoplasma distinguished the phytoplasma from all previously ...

Subfunctionalization of Paralog Transcription Factors Contributes to Regulation of Alkaloid Pathway Branch Choice in Catharanthus roseus

Frontiers in Plant Science, 2021
Catharanthus roseus produces a diverse range of specialized metabolites of the monoterpenoid indole alkaloid (MIA) class in a heavily branched pathway. Recent great progress in identification of MIA biosynthesis genes revealed that the different pathway ...

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Anti‐Inflammatory Potential of Key Phytochemicals From Humboldtia sanjappae: In Vivo Studies and Molecular Docking With MM‐GBSA Analysis

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Humboldtia sanjappae bark extract evaluated for its anti‐inflammatory potential using in vivo paw edema models and in silico molecular docking. Bioactive flavonoids, particularly neoeriocitrin, showed strong interactions with TNF‐α, COX‐2, IL‐6, and IL‐1β, highlighting the extract's multi‐target anti‐inflammatory activity and therapeutic promise ...

Virus‐Induced Gene Silencing in Calendula officinalis (Pot Marigold)

Plant Direct, Volume 10, Issue 5, May 2026.
ABSTRACT Virus‐induced gene silencing (VIGS) is a method that exploits plant antiviral defense mechanisms to downregulate endogenous genes. The technique is versatile, rapid, and widely used for functional genomics studies. Here, we report a method for VIGS in the medicinal plant, Calendula officinalis (pot marigold).

Modulatory Effects of Cirsimarin on Lung Cancer A549 Cells Migration in 2D and 3D Cultures Involves Transcriptional Regulation of Metalloproteinases

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 3, March 2026.
In 2D culture, the cirsimarin (i) decreased cell viability in both assays, (ii) induced apoptosis, (iii) reduced clonogenicity, (iv) prevented cell migration, (v) induced DNA damage, and (vi) negatively modulated gene expression. In the 3D model, reductions in spheroid viability, area, and cell migration were also observed.
