    Call number: ZSP-164-78
    In: The Geology of the South Shetland Islands
    Description / Table of Contents: The renewed volcanic activity at Deception Island appears to be closely associated with the caldera ring fault. In 1967, a submarine eruption created a new island in Telefon Bay and there was a simultaeous eruption at the land centre, 2 km. to the east. In 1969, a 5 km. fissure opened up in the glacier on the western face of Mount Pond. There were numerous vents but the most damaging aspect of the eruption was the liberation of a large volume of glacial melt water. In the 1970 eruption a series of craters built a new ship of land across Telefon Bay, partley destroying the 1967 island. The new ejecta are remarkably variable in composition. They tend to become more basic further away from the site of the 1967 island. At any particular locality later products tend to be slightly more basic than earlier ones. The distinctive Na-rich, K-poor characteristic apparently persists right through the history of Deception Island. Two basalt types are recognized, one rich in alumina and the other rich in iron. However, the high Na : K ratio is especially accentuated in the more differentiated post-caldera rocks, to which the recent eruptives belong. The Deception Island suite differs in several essential aspects from the typical calc-alkali series. These differences may be explained by persistenf loss of volatiles inhibiting the formation of amphibole.

    Massively parallel determination and modeling of endonuclease substrate specificity (2014)
    Oxford University Press
    Details
    Publication Date: 2014-12-17
    Description: We describe the identification and characterization of novel homing endonucleases using genome database mining to identify putative target sites, followed by high throughput activity screening in a bacterial selection system. We characterized the substrate specificity and kinetics of these endonucleases by monitoring DNA cleavage events with deep sequencing. The endonuclease specificities revealed by these experiments can be partially recapitulated using 3D structure-based computational models. Analysis of these models together with genome sequence data provide insights into how alternative endonuclease specificities were generated during natural evolution.

    Forests, Vol. 10, Pages 980: A Natural Capital Approach to Agroforestry Decision-Making at the Farm Scale (2019)
    MDPI
    In: Forests
    Details
    Publication Date: 2019
    Description: Background: Agroforestry systems can improve the provision of ecosystem services at the farm scale whilst improving agricultural productivity, thereby playing an important role in the sustainable intensification of agriculture. Natural capital accounting offers a framework for demonstrating the capacity of agroforestry systems to deliver sustained private benefits to farming enterprises, but traditionally is applied at larger scales than those at which farmers make decisions. Methods: Here we review the current state of knowledge on natural capital accounting and analyse how such an approach may be effectively applied to demonstrate the farm-scale value of agroforestry assets. We also discuss the merits of applying a natural capital approach to agroforestry decision-making and present an example of a conceptual model for valuation of agroforestry assets at the farm scale. Results: Our findings suggest that with further development of conceptual models to support existing tools and frameworks, a natural capital approach could be usefully applied to improve decision-making in agroforestry at the farm scale. Using this approach to demonstrate the private benefits of agroforestry systems could also encourage adoption of agroforestry, increasing public benefits such as biodiversity conservation and climate change mitigation. However, to apply this approach, improvements must be made in our ability to predict the types and amounts of services that agroforestry assets of varying condition provide at the farm or paddock scale.

    Binding of transcription factor GabR to DNA requires recognition of DNA shape at a location distinct from its cognate binding site (2016)
    Oxford University Press
    Details
    Publication Date: 2016-02-20
    Description: Mechanisms for transcription factor recognition of specific DNA base sequences are well characterized and recent studies demonstrate that the shape of these cognate binding sites is also important. Here, we uncover a new mechanism where the transcription factor GabR simultaneously recognizes two cognate binding sites and the shape of a 29 bp DNA sequence that bridges these sites. Small-angle X-ray scattering and multi-angle laser light scattering are consistent with a model where the DNA undergoes a conformational change to bend around GabR during binding. In silico predictions suggest that the bridging DNA sequence is likely to be bendable in one direction and kinetic analysis of mutant DNA sequences with biolayer interferometry, allowed the independent quantification of the relative contribution of DNA base and shape recognition in the GabR–DNA interaction. These indicate that the two cognate binding sites as well as the bendability of the DNA sequence in between these sites are required to form a stable complex. The mechanism of GabR–DNA interaction provides an example where the correct shape of DNA, at a clearly distinct location from the cognate binding site, is required for transcription factor binding and has implications for bioinformatics searches for novel binding sites.

    MicroRNA regulation of plant innate immune receptors [Plant Biology] (2012)
    National Academy of Sciences
    Details
    Publication Date: 2012-02-01
    Description: Plant genomes contain large numbers of cell surface leucine-rich repeat (LRR) and intracellular nucleotide binding (NB)-LRR immune receptors encoded by resistance (R) genes that recognize specific pathogen effectors and trigger resistance responses. The unregulated expression of NB-LRR genes can trigger autoimmunity in the absence of pathogen infection and inhibit plant growth. Despite the potential serious consequence on agricultural production, the mechanisms regulating R-gene expression are not well understood. We identified microRNA (miRNA) progenitor genes precursor transcripts, and two miRNAs [nta-miR6019 (22-nt) and nta-miR6020 (21-nt)] that guide cleavage of transcripts of the Toll and Interleukin-1 receptor-NB-LRR immune receptor N from tobacco that confers resistance to tobacco mosaic virus (TMV). We further showed that cleavage by nta-miR6019 triggers RNA-dependent RNA polymerase 6- and ribonuclease Dicer-like 4-dependent biogenesis of 21-nt secondary siRNAs “in phase” with the 22-nt miR6019 cleavage site. Furthermore, we found that processing of the 22-nt nta-miR6019 depended on an asymmetric bulge caused by mismatch in the nta-miR6019 precursor. Interestingly, coexpression of N with nta-miR6019 and nta-miR6020 resulted in attenuation of N-mediated resistance to TMV, indicating that these miRNAs have functional roles in NB-LRR regulation. Using a bioinformatics approach, we identified six additional 22-nt miRNA and two 21-nt miRNA families from three Solanaceae species—tobacco, tomato, and potato. We show that members of these miRNA families cleave transcripts of predicted functional R genes and trigger production of phased secondary 21-nt siRNAs. Our results demonstrate a conserved role for miRNAs and secondary siRNAs in NB-LRR/LRR immune receptor gene regulation and pathogen resistance in Solanaceae.

    Spatial patterns in the distribution of tropical tree species (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-29
    Description: Fully mapped tree census plots of large area, 25 to 52 hectares, have now been completed at six different sites in tropical forests, including dry deciduous to wet evergreen forest on two continents. One of the main goals of these plots has been to evaluate spatial patterns in tropical tree populations. Here the degree of aggregation in the distribution of 1768 tree species is examined based on the average density of conspecific trees in circular neighborhoods around each tree. When all individuals larger than 1 centimeter in stem diameter were included, nearly every species was more aggregated than a random distribution. Considering only larger trees (〉/= 10 centimeters in diameter), the pattern persisted, with most species being more aggregated than random. Rare species were more aggregated than common species. All six forests were very similar in all the particulars of these results.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condit, R -- Ashton, P S -- Baker, P -- Bunyavejchewin, S -- Gunatilleke, S -- Gunatilleke, N -- Hubbell, S P -- Foster, R B -- Itoh, A -- LaFrankie, J V -- Lee, H S -- Losos, E -- Manokaran, N -- Sukumar, R -- Yamakura, T -- New York, N.Y. -- Science. 2000 May 26;288(5470):1414-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Tropical Forest Science, Smithsonian Tropical Research Institute, Unit 0948, APO AA 34002-0948, USA. ctfs@tivoli.si.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10827950" target="_blank"〉PubMed〈/a〉
