Codon usage bias and selective constraints in Gentianales mitogenomes [PDF]
BMC GenomicsMitochondrial genome evolution(MGE) in flowering plants is quasi-intertwined-dynamic. MGE is driven via mutational pressures, translational selection, and functional constraints.

Beyond phylogeny: phytochemical diversity as a unique metric for biodiversity in the Gentianales [PDF]
New PhytologistSummary In contrast to phylogenetic diversity (PD), phytochemical diversity is not often utilised to measure biodiversity, although it forms an important aspect of biotic variation. The aim of this study was to explore phytochemical diversity across the flowering plant order Gentianales and the extent to which PD reliably represents phytochemical ...

Caelospermum versus Coelospermum in Rubiaceae (Gentianales): their etymologies explained [PDF]
PhytoKeysCaelospermum is the original spelling of the generic name, as it appeared in the protologue, but in literature and online databases, the variant spelling Coelospermum is often used.

Discovery of a Plant Pictet-Spenglerase With R-Stereoselectivity. [PDF]
Angew Chem Int Ed EnglStrictosidine synthases (STRs) are plant Pictet–Spenglerases catalyzing the coupling of a secoiridoid with tryptamine. All previously characterized strictosidine synthases are strictly S‐selective. Here, we report the discovery of Epi‐STR, an R‐selective STR ortholog from the medicinal plant Pogonopus speciosus.

Ancient gene clusters govern the initiation of monoterpenoid indole alkaloid biosynthesis and C3 stereochemistry inversion [PDF]
Nature CommunicationsThe inversion of C3 stereochemistry in monoterpenoid indole alkaloids (MIAs), derived from the central precursor strictosidine (3S), is essential for producing pharmacologically important 3 R MIAs and spirooxindoles such as reserpine.

Settling a family feud: a high‐level phylogenomic framework for the Gentianales based on 353 nuclear genes and partial plastomes [PDF]
American Journal of Botany, 2021 PREMISE: Comprising five families that vastly differ in species richness—ranging From Gelsemiaceae with 13 species to the Rubiaceae with 13,775 species—members of the Gentianales are often among the most species-rich and abundant plants in tropical ...

A supermatrix approach provides a comprehensive genus‐level phylogeny for Gentianales
Journal of Systematics and Evolution, 2016 Gentianales consist of Apocynaceae, Gelsemiaceae, Gentianaceae, Loganiaceae, and Rubiaceae, of which the majority are woody plants in tropical and subtropical areas.

Cell-Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis. [PDF]
Plant Biotechnol JABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...
