Ecology Letters (2010) 13: 675–684 Abstract Community assembly history is increasingly recognized as a fundamental determinant of community structure. However, little known to how may affect ecosystem functioning via its effect on Using wood‐decaying fungi model system, we provide experimental evidence that large differences in can be caused by small species immigration during assembly. Direct manipulation early resulted three‐fold fungal richness and composition and, consequence, the same...
Abstract Background There is an increasing demand for rapid biodiversity assessment tools that have a broad taxonomic coverage. Here we evaluate suite of environmental DNA (eDNA) markers coupled with next generation sequencing (NGS) span the tree life, comparing them traditional monitoring within ten 20 × meter plots along 700 elevational gradient. Results From six eDNA datasets (one from each 16S, 18S, ITS, trnL and two COI) identified sequences 109 NCBI taxonomy-defined phyla or...
The New Zealand native legume flora are represented by four genera, Sophora, Carmichaelia, Clianthus, and Montigena. adventive of contains several species introduced in the 19th century now established as serious invasive weeds. Until now, nothing has been reported on identification associated rhizobia or legumes Zealand. success may be due, at least part, to nature their rhizobial symbioses. This study set out address this issue identifying strains isolated from genera weeds: Acacia spp....
Rhytismatales (Leotiomycetes, Pezizomycotina, Ascomycota) are an order of mostly plant-associated ascomycetes with a global distribution. Well known taxa include the Rhytisma tar spots on Acer spp. and several needle-cast pathogens in genera Lophodermium Meloderma. Critical studies lacking at all taxonomic ranks from to species, particular genus taxonomy has been criticized for being unnatural. We used nuclear LSU mitochondrial SSU sequences Bayesian phylogenetic analyses define core clade...
Because chemicals introduced into the environment by humans can affect both long-term survivorship and reproduction of amphibians, discovering specific mechanisms through which these act may facilitate development plans for amphibian conservation. We investigated pheromonal system as a potential target common environmental chemicals. By treating female red-spotted newts, Notophthalmus viridescens, to commonly used insecticide, endosulfan, we found that is highly susceptible low-concentration...
The relationships of the genus Azotobacter , Azomonas macrocytogenes and Pseudomonas were revealed by comparative analysis partial 16S rRNA atpD carA recA gene sequences as concatenated nucleotide peptide sequences. Sequence similarities species indicated that these may be considered to synonyms at molecular level. In addition, show an intimate relationship with especially P . aeruginosa (the type genus). terms current circumscription should for amalgamation comprise nitrogen-fixing strains...
Species‐ and population‐specific differences in fungicide resistance aggressiveness within B otrytis makes basic data on genetic diversity important for understanding disease caused by this fungus. Genetic of was surveyed between 2008 2012 from grapes five N ew Z ealand wine‐growing regions. A total 1226 isolates were gathered symptomless flower buds at the start growing season 1331 diseased fruit harvest. Two species found, . cinerea pseudocinerea common both uckland vineyards sampled,...
High-throughput sequencing technologies using amplicon approaches have changed the way that studies investigating fungal distribution are undertaken. These powerful and time-efficient potential for first time to accurately map distributions across landscapes or changes in diversity ecological biological gradients of interest. There is no requirement a fungus form fruiting body be detected, both culturable nonculturable organisms can detected. Here we use high-throughput from bulk DNA...
Strains of Xanthomonas isolated in New Zealand from diseased endemic and introduced plants, investigated a multi‐locus sequence analysis (MLSA), were distributed primarily two species. Dysoxylum , Hardenbergia Liquidambar Magnolia Mahonia members arboricola . campestris pv. laureliae X eucalypti strains Aralia Diospyros Eriostemon Eucalyptus Metrosideros Olea formed population distinct all known spp. These latter have unique fatty acid methyl ester profile are considered to be new species,...
The behaviour in soil of root-infecting fungi is sometimes considered to be a complex subject, and the inherent principles implications are indeed commonly misunderstood by plant pathologists not specialist this field. There has, course, been no shortage reviews recently on various aspects ecology soil. Yet despite, or perhaps even because extent literature, confusion still common. From large field avail able two works can best recommended. Firstly Garrett's 1956 book (1), which provides...
Abstract Fifteen species of Chlorociboria are reported for New Zealand, including 13 new and one subspecies. All occur on decorticated wood all associated with blue‐green staining that wood. Some consistently soft, rotten wood, while others fallen remains hard appears more or less intact. The range morphological variation accepted in the genus is broader than has previously been described, especially respect to ascospore size shape. Two have filiform ascospores coil release from asci....
A comprehensive collection of different methods for extracting high-quality genomic DNA from gram-positive and -negative bacteria fungal mycelium spores is described in this chapter. Special care has been taken describing the ideal ratio biological material to chemical reagents an efficient extraction DNA, stating appropriate application molecular biology protocols (e.g., PCR or library-cloning quality).
Comparative analysis of 70 16S rDNA sequences representing 20 Rhizobium species (including pathogenic Agrobacterium spp.) was conducted using Maximum Likelihood to establish relationships multiple sequences. There is no significant internal division the clade suggest that it represents more than one genus. Plant (Agrobacterium) are distributed within The supported synonymy some (Rhizobium gallicum and mongolense) need for comparative investigations tumorigenic nodulating properties tropici...
Morphological and phylogenetic data are used to revise the genus Torrendiella. The type species, described from Europe, is retained within Rutstroemiaceae. However, Torrendiella species reported Australasia, southern South America China were found be phylogenetically distinct have been recombined in newly proposed Hymenotorrendiella. Hymenotorrendiella distinguished morphologically Rutstroemia having a Hymenoscyphus-type rather than Sclerotinia-type ascus apex. Zoellneria, linked...
Two new pathogens, Guignardia korthalsellae and Rosenscheldiella korthalsellae, are described from New Zealand's pygmy mistletoes (Korthalsella, Viscaceae). Both form ascomata on living phylloclades with minimal disruption of the tissue. Fungal hyphae within phylloclade primarily intercellular. disrupts a limited number epidermal cells immediately around erumpent ascoma, while Rosenscheldiellakorthalsellae develop externally small patches stromatic tissue that above stomatal cavities. is...
