Asparagales are a diverse monophyletic order that has numerous species (ca. 50% of monocots) including important crop plants such as Allium, Asparagus, and Vanilla, and a host of ornamentals such as irises, hyacinths, and orchids. Historically, Asparagales have been of interest partly because of their fascinating chromosomal evolution. We examine the evolutionary dynamics of Asparagales genomes in an updated phylogenetic framework that combines analyses of seven gene regions (atpl, atpB, matK, ndhF, rbcL, trnL intron, and trnL-F intergenic spacer) for 79 taxa of Asparagales and outgroups. Asparagales genomes are evolutionarily labile for many characters, including chromosome number and genome size. The history and causes of variation in chromosome number and genome size remain unclear, primarily because of the lack of data in small clades in the phylogenetic tree and the lack of comparative genetic maps, apart from Allium and Asparagus. Genomic tools such as bacterial artificial chromosome (BAC) libraries should be developed, as both molecular cytogenetic markers and a source of nuclear genes that can be widely used by evolutionary biologists and plant breeders alike to decipher mechanisms of chromosomal evolution.

Früchte, Samen und Keimpflanzen bei den Cyanastraceae ENGLER 1900 und einigen vermuteten Verwandten

Cyanastrum entwickelt aus einem chorikarpen Gynaezeum Teilfrüchte, die einsamigen, saftarmen Beeren entsprechen und sich durch einen Längsriß entlang des Dorsalmedianus öffnen. Die exo‐mesotestale Samenschale besteht aus lebenden Zellen, Endosperm ist nicht vorhanden. Der Embryo besteht aus einem voluminösen Speichercotyledo mit der in der kleinen Cotyledonarscheide eingeschlossenen Plumula. Hypocotyl und Primärwurzel fehlen. Die Keimpflanze entwickelt aus dem Epicotyl und den aufwärts folgenden Internodien die erste Sproßknolle. Die Foliation beginnt mit vier Niederblättern, denen das erste Laubblatt folgt. Das Keimblatt der Tecophilaeaceen hat im Ober‐blattbereich rein haustoriale Funktion, während das Unterblatt auf einer kurzen Scheidenröhre eine niedrige (Walleria) oder verlängerte (Cyanella) Coleoptile trägt. Bei Cyanella folgen auf den Cotyledo direkt linealische Primärblätter, bei Walleria werden zunächst einige Niederblätter entwickelt. Eriospermum besitzt einen langen, unifacialen, as‐similierenden Cotyledo vom Allium‐Typ mit winziger Cotyledonarscheide. Der Bau der Keimpflanzen spricht für die Selbständigkeit der Eriospermaceae und Cyanastraceae, während Walleria in den Rahmen der Tecophilaeaceae paät.

Coding regions of the rbcL and matK genes of cpDNA and internal transcribed spacers (ITS) of nuclear ribosomal DNA were sequenced to study phylogenetic relationships within and among all four genera of Trilliaceae: Trillium, Paris, Daiswa and Kinugasa. The rbcL gene has evolved much slower than matK and in particular ITS; hence the phylogenetic trees based on the rbcL gene show a much lower resolution than trees based on either matK or ITS. The general topology of phylogenetic trees resulting from separate parsimony analyses of the matK and ITS sequences are relatively congruent, with the exception of the placement of T. pusillum. Both matK and ITS phylogenies reveal that T. rivale diverges at the base of the trees. In both trees, Paris, Daiswa and Kinugasa form a relatively weakly supported group. Within this group, the allo‐octaploid Kinugasa japonica is the sister group of Daiswa species. The Paris–Daiswa–Kinugasa group, the major Trillium group, and T. undulatum and T. govanianum showed a loosely related topology, but their affinities are not evident according to these two molecular markers. However, phylogenetic analysis of amino acid sequences derived from matK shows that T. rivale together with clades T. undulatum–T. govanianum, Daiswa–Kinugasa and Paris is basally diverged as a sister group to the remainder of Trillium.
