Ixoroideae– Rubiaceae
IAWA Journal, Vol. 21 (4), 2000: 443–455 WOOD ANATOMY OF THE VANGUERIEAE (IXOROIDEAE– RUBIACEAE), WITH SPECIAL EMPHASIS ON SOME GEOFRUTICES by Frederic Lens1, Steven Jansen1, Elmar Robbrecht2 & Erik Smets1 SUMMARY The Vanguerieae is a tribe consisting of about 500 species ordered in 27 genera. Although this tribe is mainly represented in Africa and Mada- gascar, Vanguerieae also occur in tropical Asia, Australia, and the isles of the Pacific Ocean. This study gives a detailed wood anatomical de- scription of 34 species of 15 genera based on LM and SEM observa- tions. The secondary xylem is homogeneous throughout the tribe and fits well into the Ixoroideae s.l. on the basis of fibre-tracheids and dif- fuse to diffuse-in-aggregates axial parenchyma. The Vanguerieae in- clude numerous geofrutices that are characterised by massive woody branched or unbranched underground parts and slightly ramified un- branched aboveground twigs. The underground structures of geofrutices are not homologous; a central pith is found in three species (Fadogia schmitzii, Pygmaeothamnus zeyheri and Tapiphyllum cinerascens var. laetum), while Fadogiella stigmatoloba shows central primary xylem which is characteristic of roots. Comparison of underground versus aboveground wood shows anatomical differences in vessel diameter and in the quantity of parenchyma and fibres. Key words: Vanguerieae, Rubiaceae, systematic wood anatomy, geo- frutex. INTRODUCTION The Vanguerieae (Ixoroideae–Rubiaceae) is a large tribe consisting of about 500 spe- cies and 27 genera. Tropical Africa is the centre of diversity (about 80% of the species are found in Africa and Madagascar), although the tribe is also present in tropical Asia, Australia, and the isles of the Pacific Ocean (Bridson 1987). -

Continuing a survey of the chemistry of species of the largely continental African genus Vepris, we investigate a species previously referred to as Vepris sp. 1 of Congo. From the leaves of Vepris sp. 1 we report six compounds. The compounds were three furoquinoline alkaloids, kokusaginine (1), maculine (2), and flindersiamine (3), two acridone alkaloids, arborinine (4) and 1-hydroxy-3-methoxy-10-methylacridone (5), and the triterpenoid, ß-amyrin (6). Compounds 1-4 are commonly isolated from other Vepris species, compound 5 has been reported before once, from Malagasy Vepris pilosa, while this is the first report of ß-amyrin from Vepris. This combination of compounds has never before been reported from any species of Vepris. We test the hypothesis that Vepris sp.1 is new to science and formally describe it as Vepris teva, unique in the genus in that the trifoliolate leaves are subsessile, with the median petiolule far exceeding the petiole in length. -
Burkholderia in Rubiaceae
Symbiotic ß-Proteobacteria beyond Legumes: Burkholderia in Rubiaceae Brecht Verstraete1*, Steven Janssens1, Erik Smets1,2, Steven Dessein3 1 Plant Conservation and Population Biology, KU Leuven, Leuven, Belgium, 2 Naturalis Biodiversity Center, Leiden University, Leiden, The Netherlands, 3 National Botanic Garden of Belgium, Meise, Belgium Abstract Symbiotic ß-proteobacteria not only occur in root nodules of legumes but are also found in leaves of certain Rubiaceae. The discovery of bacteria in plants formerly not implicated in endosymbiosis suggests a wider occurrence of plant-microbe interactions. Several ß-proteobacteria of the genus Burkholderia are detected in close association with tropical plants. This interaction has occurred three times independently, which suggest a recent and open plant-bacteria association. The presence or absence of Burkholderia endophytes is consistent on genus level and therefore implies a predictive value for the discovery of bacteria. Only a single Burkholderia species is found in association with a given plant species. However, the endophyte species are promiscuous and can be found in association with several plant species. Most of the endophytes are part of the plant-associated beneficial and environmental group, but others are closely related to B. glathei. This soil bacteria, together with related nodulating and non-nodulating endophytes, is therefore transferred to a newly defined and larger PBE group within the genus Burkholderia.

The structures of compounds were determined by spectroscopic methods (NMR, MS, UV,and IR) and by comparison with previously reported data. Crude extracts of leaves and stem displayed high antimicrobial activity,with Minimum Inhibitory Concentration (MIC) (values of 10.1–16.5 and 10.2–20.5 µg/mL, respectively), against Escherichia coli, Bacillus subtilis, Pseudomonas agarici, Micrococcus luteus, and Staphylococcus warneri, while compounds 1–6 showed values ranging from 11.1 to 18.7 µg/mL or were inactive, suggesting synergistic effect. -

Salam, Tharanga Samarakoon, Sarah Shabih, Darya Raschid Farrokhi, and Cassandra L. Quave* Cite This: https://dx.doi.org/10.1021/acs.chemrev.0c00922 Read Online ACCESS Metrics & More Article Recommendations *sı Supporting Information ABSTRACT: The crisis of antibiotic resistance necessitates creative and innovative approaches, from chemical identification and analysis to the assessment of bioactivity. Plant natural products (NPs) represent a promising source of antibacterial lead compounds that could help fill the drug discovery pipeline in response to the growing antibiotic resistance crisis. The major strength of plant NPs lies in their rich and unique chemodiversity, their worldwide distribution and ease of access, their various antibacterial modes of action, and the proven clinical effectiveness of plant extracts from which they are isolated. While many studies have tried to summarize NPs with antibacterial activities, a comprehensive review with rigorous selection criteria has never been performed. In this work, the literature from 2012 to 2019 was systematically reviewed to highlight plant-derived compounds with antibacterial activity by focusing on their growth inhibitory activity. A total of 459 compounds are included in this Review, of which 50.8% are phenolic derivatives, 26.6% are terpenoids, 5.7% are alkaloids, and 17% are classified as other metabolites. A selection of 183 compounds is further discussed regarding their antibacterial activity, biosynthesis, structure−activity relationship, mechanism of action, and potential as antibiotics. Emerging trends in the field of antibacterial drug discovery from plants are also discussed. -
