The mustard family (Brassicaceae) is a scientifically and economically important family, containing the model plant Arabidopsis thaliana numerous crop species that feed billions worldwide. Despite its relevance, most phylogenetic trees of are incompletely sampled often contain poorly supported branches. Here, we present complete Brassicaceae genus-level phylogenies to date (Brassicaceae Tree Life or BrassiToL) based on nuclear (1,081 genes, 319 349 genera; 57 58 tribes) plastome (60 265 all...
Aim To evaluate competing views on the origin and distribution of New Zealand flora by testing hypothesis that geographical species is unrelated to ecological traits such as habitat requirements dispersal capabilities. Location The archipelago. Methods An analysis factors correlated with endemism for alpine plants within Zealand, biota a whole. Results Woody are highly endemic; nonendemic tend be herbaceous concentrated among dispersible ferns fern allies, orchids wetland plants. These...
The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis morphological characters and map these onto recently published tree obtained from DNA sequence data. Results previous analyses strongly support monophyly four clades that are currently treated as subgenera Nothofagus. robust well-supported, with deep stem divergences, have evolutionary equivalence other genera Fagales, can be circumscribed characters. argue molecular differences sufficient for to...
In total, 31 strains of Gram-stain-negative, rod-shaped bacteria were isolated from Sophora root nodules and authenticated as rhizobia on this host. Based 16S rRNA gene phylogeny, they shown to belong the genus Mesorhizobium, with representative ICMP 19560T, 19523T, 19535T, 19545T 19512T being related most closely Mesorhizobium sangaii SCAU7T (99.9–99.6 % similarity), cantuariense 19515T (99.7–99.6 %) ciceri UMP-CA7T (99.7–99.5 %). Additionally, novel formed distinct groups based...
Summary Plant radiations are widespread but their influence on community assembly has rarely been investigated. Theory and some evidence suggest that can allow lineages to monopolize niche space when founding species arrive early into new bioclimatic regions exploit ecological opportunities. These may subsequently reduce availability dampen diversification of later arrivals. We tested this hypothesis time‐dependent lineage dominance using the alpine flora New Zealand. estimated ages 16...
Summary Aim The aim is to use DNA sequence data test between vicariance and long range dispersal (by floating seed‐pods) explanations for the origin of Edwardsia species Sophora (Sophoreae: Papilionoideae: Leguminosae). Location This group widely distributed around South Pacific into Atlantic on both continental fragments oceanic islands. Methods sequences from an intergene region ( atp B ‐rbc L) chloroplast were determined twelve taxa (including outgroups) used these hypotheses. fossils...
Abstract A reappraisal of the conservation status New Zealand's threatened and uncommon vascular plants is presented. The list comprises 511 taxa (22% indigenous flora) in following categories: Presumed Extinct 5 taxa, Threatened 107 (comprising 24 Critically Endangered, 33 50 Vulnerable), Declining 60 Recovering 17 14 Conservation Dependent 3 undergoing Natural Population Recovery), Naturally Uncommon 204 62 rated as Sparse, Vagrant, 125 Range Restricted). Lack information on threat a...
Abstract Background Pachycladon (Brassicaceae, tribe Camelineae) is a monophyletic genus of ten morphologically and ecogeographically differentiated, presumably allopolyploid species occurring in the South Island New Zealand Tasmania. All possess chromosome pairs (2n = 20). The feasibility comparative painting (CCP) crucifer allows origin genome evolution this to be elucidated. We focus on as well its genomic relationship other species, particularly Australian Camelineae taxa. As radiation...
In total 14 strains of Gram-stain-negative, rod-shaped bacteria were isolated from Sophora longicarinata and microphylla root nodules authenticated as rhizobia on these hosts. Based the 16S rRNA gene phylogeny, they shown to belong genus Mesorhizobium, S. most closely related Mesorhizobium amorphae ACCC 19665T (99.8–99.9 %), huakuii IAM 14158T loti USDA 3471T (99.5–99.9 %) septentrionale SDW 014T (99.6–99.8 whilst ciceri UPM-Ca7T qingshengii CCBAU 33460T (99.7 shangrilense 65327T (99.6 %)....
Analysis of ITS sequences provides support for a clade that includes Carmichaelia, Clianthus, Montigena, and Swainsona. We provide node‐based definition recommend this be called Carmichaelinae. Results suggest Carmichaelinae are derived from northern hemisphere Astragalinae. The has extensively radiated in Australia, two independent lineages have diversified New Zealand. Zealand differ species richness. One lineage consists 24 placed Carmichaelia while the other corresponds to monotypic...
Abstract Nine species are reported as additional or newly substantiated fully naturalised records for the flora of New Zealand during 2‐year period 1997–1998. Notable additions invasive Eupatorium cannabinum and Acacia sophorae, which well established in Wanganui area, Myricaria germanica is relatively common along parts Waimakariri River, Canterbury. Thirty‐seven species, including two ferns, considered to be new casual plants. Thirty‐eight that were previously known from few collections...
Abstract A taxonomic treatment is provided for the Sophora microphylla complex in New Zealand. microphyllu sens. str. endemic to Zealand, and includes those plants with a distinct divaricating and/or strongly flexuose juvenile Phase, orange‐brown Yellow‐brown Juvenile stems, distant leaflets. S. chathamica reinstated at species rank, S.fulvida new combination taxon previously known as Var. fulvida, godleyi molloyi are described species. chathamica, lack phase each distinguished by number of...
Abstract Aim To date, there have been few studies investigating the phylogeography of forest trees that are widely distributed in New Zealand. Our main objective was to examine phylogeographic distribution chloroplast DNA from Zealand Sophora with respect known biogeographical regions, proposed refugia and species boundaries. A second investigate origins southern Chatham Island populations chathamica , which derive Māori translocation. Location The archipelago coastal lowland forests....
Categorical analysis of neo- and palaeo-endemism (CANAPE), phylogenetic diversity (PD) weighted endemism (PWE) were used to explore patterns diversity, biogeography in the indigenous vascular flora New Zealand archipelago. Distributional data comprising 213142 records for 436 genera 2187 species a phylogeny based mainly on rbcL sequences calculate biodiversity metrics 0.12° grid cells. Genus- species-level analyses PD revealed few significantly high-value cells mostly scattered northern...
We examined the phylogenetic relationships within Sophora sect. Edwardsia using DNA sequences from chloroplast trnQ-5′rps16 and trnHGUG-psbA intergenic spacers nuclear-encoded chloroplast-expressed glutamine synthetase gene. Sequences were analysed with median-joining networks approaches. Low sequence diversity was detected, which is consistent past genetic studies of section. Chloroplast nuclear are shared across large geographic distances. The New Zealand species did not form a...
A colonisation history for 411 extant genera and 477 lineages of the vascular flora New Zealand was constructed using plastid rbcL gene. Molecular clock crown ages suggest that Eocene-Oligocene transition extinction at 33.9 Ma critical to development as few lineages, mostly ferns conifers, predate this event. Based on dates, almost all angiosperm have established after extinction. The Oligocene marine transgression had little discernible impact formation flora, culmination inundation...

The new combination Microsorum katuae (Brownlie) Sykes ex Heenan is provided for a species endemic to Cook Islands. An earlier designation, 'Microsorum katuii Sykes', listed in the Flora of Islands 2016, not validly published as intended basionym incorrectly cited lacking information on place publication, date and page number. epithet commemorates Mrs Teremoana Katu, reflect feminine gender spelling corrected M. from incorrect masculine katuii.
Phylogenetic relationships of New Zealand species Brassicaceae belonging to the South Island endemic Ischnocarpus, Iti, Notothlaspi, and Pachycladon, indigenous Cardamine, Cheesemania, Lep- idium, Rorippa were studied using nuclear ribosomal internal transcribed spacer sequences. Results sup- port a monophyletic Notothlaspi suggest that this genus are not closely related Thlaspi, which Hooker provisionally assigned N. australe. The cosmopolitan Cardamine is paraphyletic by inclusion...
