A taxonomic backbone for the global synthesis of species diversity in the angiosperm order Caryophyllales
- 2015

Ingår i: Willdenowia. - : Botanic Garden and Botanical Museum Berlin, Freie Universitaet Berlin. - 0511-9618 .- 1868-6397. ; 45:3, s. 281-383

- The Caryophyllales constitute a major lineage of flowering plants with approximately 12500 species in 39 families. A taxonomic backbone at the genus level is provided that reflects the current state of knowledge and accepts 749 genera for the order. A detailed review of the literature of the past two decades shows that enormous progress has been made in understanding overall phylogenetic relationships in Caryophyllales. The process of re-circumscribing families in order to be monophyletic appears to be largely complete and has led to the recognition of eight new families (Anacampserotaceae, Kewaceae, Limeaceae, Lophiocarpaceae, Macarthuriaceae, Microteaceae, Montiaceae and Talinaceae), while the phylogenetic evaluation of generic concepts is still well underway. As a result of this, the number of genera has increased by more than ten percent in comparison to the last complete treatments in the Families and genera of vascular plants” series. A checklist with all currently accepted genus names in Caryophyllales, as well as nomenclatural references, type names and synonymy is presented. Notes indicate how extensively the respective genera have been studied in a phylogenetic context. The most diverse families at the generic level are Cactaceae and Aizoaceae, but 28 families comprise only one to six genera. This synopsis represents a first step towards the aim of creating a global synthesis of the species diversity in the angiosperm order Caryophyllales integrating the work of numerous specialists around the world.

Relationships of the genus Azorella (Apiaceae) and other hydrocotyloids inferred from sequence variation in three plastid markers
- 2006
-
Ingår i: Taxon. - 0040-0262. ; 55:2, s. 270-280
-
Tidskriftsartikel (refereegranskat)abstract
- Relationships of genera traditionally referred to the subfamily Hydrocotyloideae (Apiaceae), with emphasis on Azorella, were estimated using sequence variation in the markers matK, rbcL, and rps 16. The analyses were based on a combined dataset comprising 66 taxa represented by 134 sequences (29 matK, 40 rbcL, and 65 rps 16) as well as partial datasets constructed from individual markers and combinations of them. The results confirm previous observations that the hydrocotyloids are an unnatural assemblage of taxa from at least four different groups, of which one belongs to Araliaceae and the remaining ones to Apiaceae. The recently recognized subfamilies Mackinlayoideae and Azorelloideae are supported, with the possible exclusion of Platysace from the former and the addition of Asteriscium, Diposis, Domeykoa, Drusa, Homalocarpus, Laretia, Oschatzia, and Pozoa to the latter. Within Azorelloideae, the Azorella, Bowlesia, and Asteriscium clades are identified, although relationships among them are obscure. The genus Azorella occurs in two subclades that also include other genera, and is obviously paraphyletic as presently conceived. The Azorella sections Cirrhosae and Ciliatae are probably also paraphyletic.

- Volatiles are efficient mediators of chemical communication acting universally as attractant, repellent or warning signal in all kingdoms of life. Beside this broad impact volatiles have in nature, scents are also widely used in pharmaceutical, food and cosmetic industries, so the identification of new scents is of great industrial interest. Despite this importance as well as the vast number and diversity of volatile compounds, there is currently no comprehensive public database providing information on structure and chemical classification of volatiles. Therefore, the database SuperScent was established to supply users with detailed information on the variety of odor components. The version of the database presented here comprises the 2D/3D structures of approximately 2100 volatiles and around 9200 synonyms as well as physicochemical properties, commercial availability and references. The volatiles are classified according to their origin, functionality and odorant groups. The information was extracted from the literature and web resources. SuperScent offers several search options, e.g. name, Pubchem ID number, species, functional groups, or molecular weight. SuperScent is available online at: http://bioinformatics.charite.de/superscent.

-
Ingår i: Kew Bulletin. - 0075-5974. ; 62, s. 297-320
-
Tidskriftsartikel (refereegranskat)abstract
- A synopsis of the family Basellaceae is presented, covering several aspects including, e.g. history, morphology, reproduction, phylogeny, distribution, and taxonomy. The family is native to tropical and subtropical areas of the Americas, southeastern Africa, and Madagascar, and most species are succulent vines that occur in dry habitats. Four genera (Anredera Juss., Basella L., Tournonia Moq., and Ullucus Caldas) with a total of 19 species are recognised, of which two are further subdivided into subspecies. A key to all taxa is included and full nomenclature is given. Each taxon is described and discussed and representative ones are illustrated.

New names in Monotagma (Marantaceae)
- 2011
-
Ingår i: Phytotaxa. - 1179-3155. ; 20, s. 1-25
-
Tidskriftsartikel (refereegranskat)abstract
- A taxonomic revision of Monotagma (Marantaceae) concludes that this genus comprises 37 species, of which the following 18 species are here described as new: M. aurantispathum, M. breviscapum, M. congestum, M. exile, M. flavicomum, M. floribundum, M. grallatum, M. humile, M. lilacinum, M. nutans, M. papillosum, M. paradoxum, M. remotum, M. roseum, M. septentrionale, M. spathulatum, M. tuberosum, and M. uliginosum. Furthermore, the new subspecies M. grallatum subsp. subcentricifolium is described. It is also proposed that these species are best treated in two monophyletic sections, viz. Monotagma sect. Monotagma with 20 species and the new Monotagma sect. Tubulariawith 17 species. All new taxa are illustrated and described with notes on distribution and relationships, and a key to all recognized Monotagma species is given.

Diversity and distribution of floral scent
- 2006
-
Ingår i: The Botanical review. - New York : The New York Botanical Garden Press. - 0006-8101 .- 1874-9372. ; 72:1, s. 1-120
-
Tidskriftsartikel (refereegranskat)abstract
- A list of 1719 chemical compounds identified from headspace samples of floral scent is presented. The list has been compiled from some 270 published papers, including analyses of 991 species of flowering plants and a few gymnosperms, a sample including seed plants from 90 families and 38 orders. The compounds belong to seven major compound classes, of which the aliphatics, the benzenoids and phenylpropanoids, and, among the terpenes, the mono- and sesquiterpenes, occur in most orders of seeds plants. C5-branched compounds, irregular terpenes, nitrogen-containing compounds, and a class of miscellaneous cyclic compounds have been recorded in about two-thirds of the orders. Sulfur-containing compounds occur in a third of the orders, whereas diterpenes have been reported from three orders only. The most common single compounds in floral scent are the monoterpenes limonene, (E)-β-ocimene, myrcene, linalool, α- and β-pinene, and the benzenoids benzaldehyde, methyl 2-hydroxybenzoate (methyl salicylate), benzyl alcohol, and 2-phenyl ethanol, which occur in 54–71% of the families investigated so far. The sesquiterpene caryophyllene and the irregular terpene 6-methyl-5-hepten-2-one are also common and occur in more than 50% of the families. Orchidaceae are by far the best investigated family, followed by several families known to have many species with strongly scented flowers, such as Araceae, Arecaceae, Magnoliaceae, and Rosaceae. However, the majority of angiosperm families are still poorly investigated. Relationships between floral scent and pollination, chemistry, evolution, and phylogeny are briefly discussed. It is concluded that floral scent chemistry is of little use for phylogenetic estimates above the genus level, whereas the distribution and combinations of floral scent compounds at species and subspecific levels is a promising field of investigation for the understanding of adaptations and evolutionary processes in angiosperms.
