  • 2006, A SINE family widely distributed in the plant kingdom and its evolutionary history, Plant Mol
    2014
    Co-Authors: Jeffrey A. Fawcett, Taihachi Kawahara, Hitoshi Watanabe, Yasuo Yasui
    Abstract:

    The distribution and evolution of Au SINE in plants were examined. Au SINE is a short interspersed element first identified in Aegilops umbellulata, a close relative of wheat. The Au SINE was previously found in species such as wheat, maize, tobacco, and tomato, but not in rice. In this study, we first searched public databases, and next examined the presence of Au in a broad range of plant species by PCR using internal primers of Au. Although Au is likely to be absent from many species including rice, it was identified in many Gramineae, Solanaceae, and Fabaceae species, and also in a basal angiosperm species, Asimina triloba. Phylogenetic studies suggest that Au SINE originated before the divergence of monocots and eudicots. Au SINE sequences of Asimina, Triticum, Zea, Nicotiana, Lotus, Medicago, and Glycine were aligned and compared. Although sequences of Au were highly conserved among distantly related species, every Au element in Glycine had a 16 bp deletion and its 3 ¢ end differed from sequences of other species. This type of Au could only be found in G. max, and not in other species including other Fabaceae species such as M. truncatula and L. japonicus. This is the first report of a plant SINE family present in multiple lineages, and the evolution of Au SINE in the plant kingdom, especially in Gramineae and Fabaceae is discussed

  • New sequestrate fungi from Guyana: Jimtrappea guyanensis gen. sp. nov., Castellanea pakaraimophila gen. sp. nov., and Costatisporus cyanescens gen. sp. nov. (Boletaceae, Boletales)
    IMA Fungus, 2015
    Co-Authors: Matthew E. Smith, Todd F. Elliott, Kevin R. Amses, Keisuke Obase, M. Catherine Aime, Terry W. Henkel
    Abstract:

    Jimtrappea guyanensis gen. sp. nov., Castellanea pakaraimophila gen. sp. nov., and Costatisporus cyanescens gen. sp. nov. are described as new to science. These sequestrate, hypogeous fungi were collected in Guyana under closed canopy tropical forests in association with ectomycorrhizal (ECM) host tree genera Dicymbe (Fabaceae subfam. Caesalpinioideae), Aldina (Fabaceae subfam. Papilionoideae) , and Pakaraimaea (Dipterocarpaceae). Molecular data place these fungi in Boletaceae (Boletales, Agaricomycetes, Basidiomycota) and inform their relationships to other known epigeous and sequestrate taxa within that family. Macro- and micromorphological characters, habitat, and multi-locus DNA sequence data are provided for each new taxon. Unique morphological features and a molecular phylogenetic analysis of 185 taxa across the order Boletales justify the recognition of the three new genera.

  • new species and reports of inocybe agaricales from guyana
    Kurtziana, 2012
    Co-Authors: Brandon P Matheny, Catherine M Aime, Matthew E. Smith, Terry W. Henkel
    Abstract:

    Since our last report in 2003, we document the discovery of an additional seven species of Inocybe from Dicymbe (Fabaceae) forests of Guyana in northeastern South America. Of these, five are described as new: I. enigmatica, I. lepidotella, I. magnifolia, I. marginata, and I. rhodella. Two additional species described originally from Brazil and Venezuela, I. amazoniensis and I. lasseri, respectively, are reported as new records for Guyana. This raises the number of Inocybe species reported from Guyana to eleven. Molecular identifications of ectomycorrhizal root tips of species of Dicymbe and Aldina (Fabaceae) match five of the known Inocybe species from Guyana. An additional eight Inocybe ITS sequences distinct at the species level were detected from ectomycorrhizal root tips of Fabaceae in Guyana but at present match no known morphological species represented in regional or global sequence databases. A revised key to species of Inocybe from Guyana is presented together with illustrations of new taxa. Data from examination of types of I. amazoniensis and I. matrisdei are presented, as well as supplementary reports of I. epidendron and I. pulchella, both originally described from Guyana.

  • ectomycorrhizal fungal diversity and community structure on three co occurring leguminous canopy tree species in a neotropical rainforest
    New Phytologist, 2011
    Co-Authors: Matthew E. Smith, Catherine M Aime, Terry W. Henkel, Alexander K Fremier, Rytas Vilgalys
    Abstract:

    Summary • The ectomycorrhizal (ECM) symbiosis was historically considered restricted to the temperate zones, but recent studies have shown the importance of this symbiosis across the tropics. We examined ECM fungal diversity, host plant phylogeny and ECM host preferences in a rainforest dominated by the leguminous host plants Dicymbe corymbosa, Dicymbe altsonii and Aldina insignis. • Ectomycorrhizal fungi were identified by internal transcribed spacer rDNA sequencing and host species were verified with chloroplast trnL sequencing. To test whether Dicymbe and Aldina represent independent gains of the ECM symbiosis, we constructed a Fabaceae phylogeny using MatK and trnL. We identified four independent ECM lineages within the Fabaceae. • We detected a diverse community of 118 ECM species dominated by the ⁄ clavulina, ⁄ russula-lactarius, ⁄ boletus, and ⁄ tomentella-thelephora lineages. Ectomycorrhizal species in Agaricales, Atheliales and Polyporales may represent previously unrecognized tropical-endemic ECM lineages. Previous studies suggested that ECM fungi did not diversify in the tropics, but the ⁄ clavulina lineage appears to have a center of diversity in tropical South America. • Dicymbe and Aldina represent independent gains of the ECM symbiosis in Fabaceae but their fungal symbionts showed no host preferences. Spatial factors are more important than hosts in structuring the ECM fungal community in this ecosystem.

  • Hierarchical traits distances explain grassland Fabaceae species' ecological niches distances
    Frontiers in Plant Science, 2015
    Co-Authors: Florian Fort, Claire Jouany, Pablo Cruz
    Abstract:

    Fabaceae species play a key role in ecosystem functioning through their capacity to fix atmospheric nitrogen via their symbiosis with Rhizobium bacteria. To increase benefits of using Fabaceae in agricultural systems, it is necessary to find ways to evaluate species or genotypes having potential adaptations to sub-optimal growth conditions. We evaluated the relevance of phylogenetic distance, absolute trait distance and hierarchical trait distance for comparing the adaptation of 13 grassland Fabaceae species to different habitats, i.e., ecological niches. We measured a wide range of functional traits (root traits, leaf traits, and whole plant traits) in these species. Species phylogenetic and ecological distances were assessed from a species-level phylogenetic tree and species’ ecological indicator values, respectively. We demonstrated that differences in ecological niches between grassland Fabaceae species were related more to their hierarchical trait distances than to their phylogenetic distances. We showed that grassland Fabaceae functional traits tend to converge among species with the same ecological requirements. Species with acquisitive root strategies (thin roots, shallow root systems) are competitive species adapted to non-stressful meadows, while conservative ones (coarse roots, deep root systems) are able to tolerate stressful continental climates. In contrast, acquisitive species appeared to be able to tolerate low soil-P availability, while conservative ones need high P availability. Finally we highlight that traits converge along the ecological gradient, providing the assumption that species with similar root-trait values are better able to coexist, regardless of their phylogenetic distance.

  • Grassland Fabaceae grown under contrasted phosphorus supply induced changes in rhizospheric soil phosphatase activity
    2014
    Co-Authors: Florian Fort, Pablo Cruz, Stroia Ciprian, Claire Jouany
    Abstract:

    Fabaceae performances in low fertility agro systems rely on their capacity to acquire phosphorus (P) since their growth is highly limited by P shortage. Recent work conducted on grassland’s legumes demonstrated, that different roots strategies exist within Fabaceae family resulting in a large range of responses to P stress. Our objective is to evaluate to what extend rhizospheric soil phosphatase activity is related to Fabaceae response to P limitation. In that purpose, we grew in a green house, 13 grassland Fabaceae species under two levels of P availability for more than 100 days. At harvest, rhizospheric soil were sampled then analysed for alkaline phospho-monoesterase activity together with bulk soil (control). Results show a significant effect of plant on species identity on rhizospheric phosphatase activity, Anthylis vulneraria and Vicia cracca induce high phosphatase activity in their rhizsospheric soil while Securigera varia and Trifolium pratense induce low phosphatase activity. There is also a significant and negative effect of P supply on phosphatase activity of rhizospheric soil. The activity measured for the bulk soil is always significantly lower than the one measured for the rhizospheric soil. It was interesting to notice that phosphatase activities measured for Fabaceae are not different from those obtained for Poaceae grown under similar conditions. We showed that Fabaceae species induce austrong increase of the phosphatase activity in their rhizospheric soil in comparison to bulk soil. However, further work is needed to understand the link between rhizospheric soil activity and P stress tolerance.
