A new protocol for rotaxane synthesis

Stuart J Cantrill, David A Fulton, Matthew C.T Fyfe, J.Fraser Stoddart, Andrew J.P White, David J Williams
1999 Tetrahedron Letters  
A novel [2]rotaxane was synthesized when an aniline-bearing [2]pseudorotaxane--generated by the hydrogen bond-driven threading of a dibenzylammonium filament through the cavity of the macrocyclic polyether dibenzo[24]crown-8--was stoppered via reaction with a bulky isocyanate. Complete characterization of the [2]rotaxane was accomplished by NMR spectroscopy, mass spectrometry and X-ray crystallography.

New constraints on atmospheric CO2concentration for the Phanerozoic

Peter J. Franks, Dana L. Royer, David J. Beerling, Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, Joseph A. Berry
2014 Geophysical Research Letters  
Earth's atmospheric CO 2 concentration (c a ) for the Phanerozoic Eon is estimated from proxies and geochemical carbon cycle models. Most estimates come with large, sometimes unbounded uncertainty. Here, we calculate tightly constrained estimates of c a using a universal equation for leaf gas exchange, with key variables obtained directly from the carbon isotope composition and stomatal anatomy of fossil leaves. Our new estimates, validated against ice cores and direct measurements of c a , are

Uncertainties, obtained from Monte Carlo simulations, are typically less than for c a estimates from other approaches. These results provide critical new empirical support for the emerging view that large (~2000-3000 ppm), long-term swings in c a do not characterize the post-Devonian and that Earth's long-term climate sensitivity to c a is greater than originally thought.

Long-read assemblies reveal structural diversity in genomes of organelles - an example with Acacia pycnantha [article]

Anna E Syme, Todd G.B. McLay, Frank Udovicic, David J Cantrill, Daniel J Murphy
2020 bioRxiv   pre-print
Although organelle genomes are typically represented as single, static, circular molecules, there is evidence that the chloroplast genome exists in two structural haplotypes and that the mitochondrial genome can display multiple circular, linear or branching forms. We sequenced and assembled chloroplast and mitochondrial genomes of the Golden Wattle, Acacia pycnantha, using long reads, iterative baiting to extract organelle-only reads, and several assembly algorithms to explore genomic
more » ... . Using a de novo assembly approach agnostic to previous hypotheses about structure, we found different assemblies revealed contrasting arrangements of genomic segments; a hypothesis supported by mapped reads spanning alternate paths.

The Global Genome Biodiversity Network (GGBN) Data Portal

Gabriele Droege, Katharine Barker, Jonas J. Astrin, Paul Bartels, Carol Butler, David Cantrill, Jonathan Coddington, Félix Forest, Birgit Gemeinholzer, Donald Hobern, Jacqueline Mackenzie-Dodds, Éamonn Ó Tuama (+4 others)
2013 Nucleic Acids Research  
The Global Genome Biodiversity Network (GGBN) was formed in 2011 with the principal aim of making high-quality well-documented and vouchered collections that store DNA or tissue samples of biodiversity, discoverable for research through a networked community of biodiversity repositories. This is achieved through the GGBN Data Portal (http://data.ggbn.org), which links globally distributed databases and bridges the gap between biodiversity repositories, sequence databases and research results.
more » ... vances in DNA extraction techniques combined with next-generation sequencing technologies provide new tools for genome sequencing. Many ambitious genome sequencing projects with the potential to revolutionize biodiversity research consider access to adequate samples to be a major bottleneck in their workflow. This is linked not only to accelerating biodiversity loss and demands to improve conservation efforts but also to a lack of standardized methods for providing access to genomic samples. Biodiversity biobank-holding institutions urgently need to set a standard of collaboration towards excellence in collections stewardship, information access and sharing and responsible and ethical use of such collections. GGBN meets these needs by enabling and supporting accessibility and the efficient coordinated expansion of biodiversity biobanks worldwide.
