‘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 ...

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.

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT
