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.

Ancient gene clusters govern the initiation of monoterpenoid indole alkaloid biosynthesis and C3 stereochemistry inversion [PDF]

Nature Communications
The 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.

Leaf defoliation and Tabernaemontana rotensis (Asterids: Gentianales: Apocynaceae) flower induction and fruit development

Journal of Threatened Taxa, 2023
Tabernaemontana rotensis (Kaneh.) P.T. Li is an attractive small tree that is endemic to the islands of Guam and Rota. Conservation efforts of the threatened population are constrained by lack of research. Understanding the ecology of flower and fruit development is fundamental to successful conservation of threatened angiosperms. This study determined

CLADISTICS AND FAMILY LEVEL CLASSIFICATION OF THE GENTIANALES [PDF]

Cladistics, 1994
Abstract— The most recent classification of the angiosperm order Gentianales (Thorne, 1992) includes four principal families: Apocynaceae, Gentianaceae, Loganiaceae, and Rubiaceae. Ever since Bentham (1857) the status of Loganiaceae has been questioned, and several segregates of that family have been proposed both before and after his treatment.

A consensus classification for the order gentianales with additional details on the suborder apocynineae [PDF]

The Botanical Review, 1995
The Gentianales as circumscribed by Benson, Cronquist, Dahlgren, Goldberg, Hey wood et al., Melchior, Stebbins, Takhtajan, and Thorne is investigated. From these a consensus classification (not in the cladistic sense) or classificatory model for the order is proposed.

Comparative anatomy and genetic bases of fruit development in selected Rubiaceae (Gentianales) [PDF]

American Journal of Botany, 2021
AbstractPremiseThe Rubiaceae are ideal for studying the diversity of fruits that develop from flowers with inferior ovary. We aimed to identify morpho‐anatomical changes during fruit development that distinguish those derived from the carpel versus the extra‐carpellary tissues.

Habitat Type Influences Danaus plexippus (Lepidoptera: Nymphalidae) Oviposition and Egg Survival on Asclepias syriaca (Gentianales: Apocynaceae) [PDF]

Environmental Entomology, 2019
AbstractAs agricultural practices intensify, species once common in agricultural landscapes are declining in abundance. One such species is the monarch butterfly (Danaus plexippus L.), whose eastern North American population has decreased approximately 80% during the past 20 yr.

The genome sequence of field madder, Sherardia arvensis L., 1753 (Rubiaceae) [version 1; peer review: 2 approved] [PDF]

Wellcome Open Research
We 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.
