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.

Hoya spectatissima (Gentianales, Apocynaceae), a new species from Yunnan, China [PDF]
PhytoKeys, 2023 Hoya spectatissima, a new species from Yunnan Province, China, is described and illustrated. Hoya spectatissima is morphologically similar to H. lyi, but can be easily distinguished from the latter by its succulent leaves that are 2‒4.5 cm long (vs ...

Floristic Account of Apocynaceae (Gentianales) in Tunisia: New Additions to National and North African Flora with Nomenclatural Updates and Taxonomic Notes [PDF]
PlantsA taxonomic revision of the family Apocynaceae (Gentianales) from Tunisia is presented. Field surveys carried out during the last two decades allowed us to identify new records at the national level, i.e., Asclepias curassavica, Carissa macrocarpa ...

Comparative analysis of mitochondrial genomes of two alpine medicinal plants of Gentiana (Gentianaceae) [PDF]
PLoS ONE, 2023 Gentiana crassicaulis and G. straminea are alpine plants of Gentiana with important medicinal value and complex genetic backgrounds. In this study, the mitochondrial genomes (mtDNAs) of these two species were sequenced. The mtDNAs of G.

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 ...

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.

A revised time tree of the asterids: establishing a temporal framework for evolutionary studies of the coffee family (rubiaceae). [PDF]
PLoS ONE, 2015 Divergence time analyses in the coffee family (Rubiaceae) have all relied on the same Gentianales crown group age estimate, reported by an earlier analysis of the asterids, for defining the upper age bound of the root node in their analyses. However, not

The genome sequence of field madder, Sherardia arvensis L., 1753 (Rubiaceae) [version 1; peer review: 2 approved] [PDF]
Wellcome Open ResearchWe present a genome assembly from an individual Sherardia arvensis (field madder; Tracheophyta; Magnoliopsida; Gentianales; Rubiaceae). The genome sequence is 440.9 megabases in span. Most of the assembly is scaffolded into 11 chromosomal pseudomolecules.
