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

open access: hybridAmerican 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.

The Role of Plant Evolutionary History in Shaping the Variation in Specific Leaf Area Across China. [PDF]

open access: yesEcol Evol
In this study, we analyzed the influences of climatic conditions and soil properties on the specific leaf area (SLA), calculated the phylogenetic signals of SLA, and quantified the relative contributions of evolutionary history to the spatial variation in SLA. We underscored the importance of evolutionary history in shaping the spatial variation of SLA

Floral and reproductive biology of Sarpagandha Rauvolfia serpentina (Gentianales: Apocynaceae) in semi-arid environment of India

open access: goldJournal of Threatened Taxa, 2011
Sarpagandha plant Rauvolfia serpentina (Linn.) Benth., ex Kurz bears small, tubular white to pinkish flowers with gamopetalous corolla, containing nectar deep at the base of the corolla tube. Psychophilous mode of pollination appears to be prevalent. Flowering occurs during two summer months.

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

open access: goldJournal 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

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid-independent manner. [PDF]

open access: yesPlant J
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

Discrimination of the Genus Leontopodium Species (Gentianales: Asteraceae) Based on RAPD [PDF]

open access: bronzeJournal of Forest and Environmental Science, 2015
Abstract Korean L. leiolepis of the genus Leontopodium could be discriminate from the foreign L. alpinum using random amplified polymorphic DNA (RAPD). Among the 12 URP markers used for the detection, the URP-5 marker and the URP-7 marker detected polymorphic DNA bands, ranging from 400-1000 bp in the size of amplified DNA fragments.Key Words ...

A revised time tree of the asterids: establishing a temporal framework for evolutionary studies of the coffee family (rubiaceae). [PDF]

open access: yesPLoS 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
