Phylogeny of the Asparagales based on three plastid and two mitochondrial genes [PDF]
American Journal of Botany, 2012 • Premise of the study: The Asparagales, with ca. 40% of all monocotyledons, include a host of commercially important ornamentals in families such as Orchidaceae, Alliaceae, and Iridaceae, and several important crop species in genera such as Allium, Aloe, Asparagus, Crocus, and Vanilla.

Constraints and selection: insights from microsporogenesis in Asparagales
Evolution & Development, 2007SUMMARY Developmental constraints have been proposed to interfere with natural selection in limiting the available set of potential adaptations. Whereas this concept has long been debated on theoretical grounds, it has been investigated empirically only in a few studies.

Biogeography of the monocotyledon astelioid clade (Asparagales)
2021The astelioid families (Asteliaceae, Blandfordiaceae, Boryaceae, Hypoxidaceae, and Lanariaceae) have centers of diversity in Australasia and temperate Africa, with secondary centers of diversity in Afromontane Africa, Asia, and Pacific Islands. The global distribution of these families makes this an excellent lineage to test if current distribution ...

Ledebouria socialis As a Key to Understanding the Evolution of Gynoecium in Asparagales
Doklady Biological Sciences, 2022For Ledebouria socialis, a superior ovary with interlocular septal nectaries that are confined to both ascidiate and plicate zones of the carpel is typical. It is impossible to describe the gynoecium zonation consistently, since the existing terminology does not allow us to display all its peculiarities. A part of the nectaries located in the gynophore

Structural diversity of fructans from members of the order Asparagales in New Zealand
Phytochemistry, 2003The water-soluble carbohydrates (WSCs) extracted from the underground parts of Arthropodium cirratum, Astelia banksii, Bulbinella hookeri, Dianella nigra and Xeronema callistemon, and the flower stem of Phormium tenax have been investigated. Extracts of A. cirratum, B. hookeri, D. nigra and P. tenax contained 108.4, 28.1, 41.9 and 29.7 mg gFW(-1) WSCs,

Embryology, cytology and systematics ofHemiphylacus, Asparagus andAnemarrhena (Asparagales)
Plant Systematics and Evolution, 1998A detailed description of ovule development and embryology ofHemiphylacus alatostylus is given, together with a chromosome count and karyotype. Comparative data are presented forAsparagus andAnemarrhena, since earlier analysis ofrbcL sequence data indicated a relationship between them.Hemiphylacus should be included inAsparagaceae. A close relationship

RNA editing has been lost in the mitochondrial cox3 and rps13 mRNAs in Asparagales
Biochimie, 2007RNA editing in plant mitochondria alters the RNA sequence by converting C-to-U or U-to-C at a specific site. We investigated the requirement for RNA editing in the complete genomic sequences of the gene encoding the cytochrome oxidase subunit III (cox3) and the ribosomal protein S13 (rps13) in 59 closely related species within the Asparagales and ...

Sansevieria pfennigii (Ruscaceae, Asparagales)
2021Sansevieria pfennigii, which to date has been a doubtful species, is confirmed as extant by a recent collection from the Lindi Region in southern Tanzania. The original description of the species, which is based on herbarium material only, is here emended based on additional observations recorded from living plants, including fruits that were ...

Floral structure and development and systematic aspects of some 'lower' Asparagales
Plant Systematics and Evolution, 2001Floral structure and development of representatives of Asteliaceae, Blandfordiaceae, Boryaceae, Doryanthaceae, and Hypoxidaceae, all members of the `lower' Asparagales, were studied comparatively. The results are discussed in the light of new molecular systematic studies, but also with regard to established morphological characters in related groups ...

A karyological review of the orders Asparagales and Liliales (Monocotyledonae)
Feddes Repertorium, 1995AbstractKaryology of the Asparagales and Liliales is reviewed with references to their morphology, embryology, DNA analyses, and other aspects. Asparagaceae, Ruscaceae, Dracenaceae, and Nolinaceae may share a common ancestor withx= 10, and Tecophilaeaceae, Cyanastraceae, and Ixioliriaceae withx= 12.Tricyrtis(Uvulariaceae) is karyologically similar ...
