  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

Link (family Fabaceae), known as broom, is having a major impact on native vegetation in naturally treeless sub-alpine frost-hollow areas (c. 32o 01’ 37” S, 151o 26’ 12” E’, 1440 m elevation) at the Barrington Tops, New South Wales, in south-eastern Australia. This vegetation is of limited extent and has significant biogeographical and ecological importance. Nine paired 10 m line transects were compared, with one of the pair in areas of almost 100% Cytisus scoparius and the other in adjacent areas without Cytisus scoparius. Results were compared with species recorded from this area in the 1930s. There are obvious differences in native vegetation in areas with and without Cytisus scoparius. On average there were 5.1 (range 2–10) species per 10 m in areas of almost 100% Cytisus scoparius cover and 17.0 (12–25) species per 10 m in areas adjacent to infested areas but without Cytisus scoparius.

The Xanthorrhoeaceae has the largest representation with 10 genera and 99 species. Most are endemic with a few species of Lomandra and Romnalda extending to neighbouring islands. The family includes the spectacular blackboys and grass-trees. The Iridaceae is largely represented by naturalised species with 52 of the 78 species being introduced. Many of the introductions are ornamentals and several have become serious weeds. Patersonia is the largest genus with all 17 species endemic. Some of these are cultivated as ornamentals. The Dioscoreaccae is a family of economic significance, particularly in the old world tropics where some species are cultivated or collected for their tubers and bulbils. In Australia there are 5 species, one of which is a recent introduction. The endemic and native species, commonly known as yams, are traditionally eaten by the Aborigines.

  • Molecular Systematics of the Lomandra Labill. Complex
    Molecular Systematics of the Lomandra Labill. Complex (Asparagales: Laxmanniaceae) by Matthew J. Donnon, B.Sc.Hons A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Ecology and Evolutionary Biology Faculty of Science The University of Adelaide September 2009 1. General Introduction 1.1 General Introduction Laxmanniaceae (Monocotyledonae: Asparagales) are a tropical to temperate family of 14 genera with approximately 180 species from Australasia, SE Asia, the Mascarenes, New Caledonia, New Guinea, New Zealand, North and South America and the Pacific Islands (Conran 1998). Nevertheless, they are primarily an Australian family with many species spread across the continent, surviving and flourishing in an extraordinary variety of environments ranging from the monsoon tropics and subtropical rainforest to temperate Mediterranean heathlands and coastal sand dunes. Laxmanniaceae have a long historical record, with fossilised leaves of Paracordyline Conran species recognised from Eocene South Australia (Conran and Christophel, 1998), Oligocene Kerguélen Islands (Conran, 1997a) and Cordyline Comm. ex R.Br. pollen identified in Lower Miocene New Zealand sediments (Couper, 1953). Molecular dating work by Janssen and Bremer (2004) based on rbcL sequence data estimated the divergence origin of the Asparagaceae sensu lato (a wider family which includes Laxmanniaceae and thus Lomandra) at approximately 90 million years ago using nonparametric rate smoothing. This age estimation was given additional support by further work incorporating geological area cladogram comparisons and dispersal-vicariance analysis (Bremer and Janssen 2006). This latter study also indicated a South Gondwanan origin for the group. The plants are generally rhizomatous or tufted-caespitose, but the different species and genera are highly variable in size and morphology.

    PHYLOGENOMIC PLACEMENT OF ANCIENT POLYPLOIDY EVENTS WITHIN THE POALES AND AGAVOIDEAE (ASPARAGALES) by MICHAEL RAMON MCKAIN (Under the Direction of James H. Leebens-Mack) ABSTRACT Polyploidy has been an important component to the evolution of angiosperms. Recent studies have shown that an ancient polyploid (paleopolyploid) event can be traced to the lineage leading to the diversification of all angiosperms, and it has long been known that recurring polyploid events can be found throughout the angiosperm tree of life. With the advent of high- throughput sequencing, the prominent place of paleopolyploid events in the evolutionary history of angiosperms has become increasingly clear. Polyploidy is thought to spur both diversification and trait innovation through the duplication and reworking of gene networks. Understanding the evolutionary impact of paleopolyploidy within the angiosperms requires knowing when these events occurred during angiosperm evolution. This study utilizes a high-throughput phylogenomic approach to identify the timing of paleopolyploid events by comparing the origin of paralogous genes within a gene family to a known species tree. Transcriptome data derived from taxa in lineages with previously little to no genomic data, were utilized to assess the timing of duplication events within hundreds of gene families. Previously described paleopolyploid events in the history of grasses, identified through analyses of syntenic blocks within Poaceae genomes, were placed on the Poales phylogeny and the implications of these events were considered. Additionally, a previously unverified paleopolyploidy event was found to have occurred in a common ancestor of all members of the Asparagales and commelinids (including Poales, Zingiberales, Commelinales, Arecales and Dasypogonales). The phylogeny of the Asparagaceae subfamily Agavoideae was resolved using whole chloroplast genomes, and two previously unknown paleopolyploid events were described within the context of that phylogeny.

Here we report on the application of this method to estimat- ing the molecular phylogeny of core Asparagales, investigating plastid gene losses, assembling complete plastid genomes, and determining the type and quality of assembled genomic data attainable from Illumina 80 – 120-bp reads. • Methods: We sequenced total genomic DNA from samples in two lineages of monocotyledonous plants, Poaceae and Aspara- gales, on the Illumina platform in a multiplex arrangement. We compared reference-based assemblies to de novo contigs, evaluated consistency of assemblies resulting from use of various references sequences, and assessed our methods to obtain sequence assemblies in nonmodel taxa.

México 56: 45-56 (1995) Hutchinson (Agavales) vs. Huber y Dahlgren (Asparagales): análisis moleculares sobre la filogenia y evolución de la familia Agavaceae sensu Hutchinson dentro de las monocotiledóneas LUIS E. EGUIARTE Departamento de Ecología Evolutiva, Centro de Ecología, Universidad Nacional Autónoma de México, Apartado Postal 70-275, C.P. 04510, D.F., México. Resumen: Para explorar diferentes ideas sobre la filogenia de las monocotiledóneas, y en particular sobre las Agavaceae se ns u Hutchinson (1934, 1959) y su relación con grupos emparentados dentro de las Asparagales, se analizó la secuencia de ADN del gen del cloroplasto rbcL para 134 especies (118 monocotiledóneas, empleando 16 dicotiledóneas paleohierbas como grupo externo). Se llevaron a cabo análisis de parsimonia utilizando métodos de distancia (neighbor-joining y UPGMA) y de máxima verosimilitud. Las filogenias muestran que Acorus calamus es la representante actual más cercana a las monocotiledóneas ancestrales. Los diferentes análisis identifican tres principales linajes evolutivos en las Agavaceae sensu Hutchinson: 1) El de las Agavaceae sensu stricto (Agave, Man/reda, Beschon ~ eria, Hesperaloe y Yucca), Hasta (Funkiaceae) y Chlorophytum (Anthericaceae). 2) El grupo que incluye a las Nolinaceae (Nolina, Beaucarnea y Dasylirion), a Sansevieria (Dracaenaceae) y a Danae (Rúscaceae). 3) El formado por las Asphodelaceae (Aloe, Haworthia y Kniphofia) y Dianella (Phormiaceae). Estos linajes contienen a la mayoría de las Asparagales tal como fueron definidas por Huber (1969) y Dahlgren et al. (1985). También se estimó un reloj molecular para obtener las fechas de divergencia entre los grupos relacionados con las Agavaceae.
