Biological Network analysis
We have pioneered network analysis of foraging basidiomycete fungi growing in unconstrained microcosms (Bebber et al. 2007a; Bebber et al. 2007b; Boddy et al. 2009; Boddy et al. 2010; Fricker et al. 2008a; Fricker et al. 2007; Fricker et al. 2008b; Heaton et al. 2010; Rotheray et al. 2008). We have shown using graph-theoretic analysis of digitised networks, that these indeterminate, de-centralized systems can yield adaptive networks with both high transport capacity and robustness to damage, but at a relatively low cost, through a 'Darwinian' process of selective reinforcement of key transport pathways and recycling of redundant routes (Bebber et al. 2007a). Furthermore, fungal networks are able to dynamically modify link strengths and local connectivity when subject to experimental attack to readjust the balance between transport capacity, robustness to damage and resource allocation, resulting in increased resilience as the environment becomes more challenging (Boddy et al. 2010; Rotheray et al. 2008).
Currently network extraction is a laborious manual exercise. We have recently developed high-throughput, automated imaging, visualisation and network analysis protocols to extract biological network organisation using Phase Congruency Tensors (PCTs) to specifically enhance curvi-linear features in the image (Obara, 2012a-c). This approach can rapidly extract networks with 106 links in a few minutes with high fidelity.
The underlying mechanisms leading to the emergence of adaptive behaviour in macroscopic mycelial networks are unknown. However, models based on growth-induced mass flow through the experimentally determined macroscopic networks provide a high level of explanatory power for the transport of added radiolabel (Heaton et al. 2010; Heaton et al. 2012). We infer that bio-physical hydraulic coupling and internal flows observed in macroscopic networks may act as the central mechanism enabling coordinated growth across the complete range of scales in networked organisms.
The work on fungal networks has also led to collaboration with Toshiyuki Nakagaki and his team in Hakodate to understand network formation in the acellular slime mold Physarum polycephalum. We have recently shown that it can form networks with comparable efficiency, fault tolerance, and cost to those of real-world infrastructure networks such as the Tokyo rail system (Tero et al. 2010), which was awarded an IgNobel prize in 2010. The core mechanisms needed for adaptive network formation can be captured in a biologically inspired mathematical model that may be useful to guide network construction in other domains.
We have a long track record in the development and application of imaging techniques to map redox homeostasis and signalling plant and fungal systems (Moore et al., 2006; Brandizzi et al,. 2002). We developed a system for quantitative imaging of total cytoplasmic glutathione (GSH) in vivo following GST-catalysed conjugation to monochlorobimane (MCB) to give a fluorescent glutathione-bimane (GSB) adduct. This has allowed measurement of concentrations of GSH in defined cell types in intact tissues, to dissect the control of GSH synthesis and to analyse activities of GSH-based xenobiotic detoxification pathways in intact tissues with sub-cellular resolution. The imaging assay is technically complex (Fricker et al., 2000; Meyer and Fricker, 2000; Meyer et al., 2001), but now successfully applied to GSH measurements in several different types of tissues including roots (Sanchez-Fernandez et al., 1997; Fricker et al., 2001), trichomes (Gutiérrez-Alcalá et al 2000), suspension culture cells (Meyer and Fricker, 2002), and mesophyll, epidermal and guard cells of wild type and transgenic poplar over-expressing g-ECS (Hartmann et al 2003), mutants in ER morphology (Au et al., 2012), and most recently pathogenic fungi (Samalova et al., unpub.). This work has now been combined with in vivo redox imaging with using ratiometric roGFP1 and roGFP2 (Schwarzlander et al., 2008; Marty et al., 2009) and application of these probes to measure mitochondrial redox state under a range of stress conditions (Lehmann et al., 2008; Schwarzlander et al., 2009) and in mutants deficient in MnSOD (Morgan et al 2008). We have also shown that cpYFP does not act as a reporter for superoxide, but behaves as an effective pH indicator in vivo, and reveals the presence of transient alkalinisation events associated with flickering in mitochondrial membrane potential (Schwarzlander et al. 2011; 2012). Most recently, we have started to move these approaches across to the pathogenic rice last fungus, Magnaporthe oryzae, coupling the redox and ROS probes with nitric oxide measurements.
- So far in 2012, I have been over to Harvard again for a Radcliffe workshop on networks that acted as a precursor to a successful HFSP grant over three years with Anne Pringle and Michael Brenner to examine network formation and function across the diverse taxa. I also contributed to the Exeter Imaging Network, building on the links in place with John Love and George Littlejohn on ratio imaging techniques.
- In 2011, there was a good mix of meetings across all the areas the lab works on including Botanical Microscopy in Wageningen, Fungal Biology at Exeter and Network Theory and Applications in Warwick.
- In 2010, I visited Harvard to give talks to the Systems Biology group at the Medical School, Nicholas Christakis's group in Sociology, and Anne Pringle's group in OEB. The ash cloud conveniently added another week to a very pleasant stay. I also gave talks at the ISC-PIF Workshop on Transportation Networks in Nature and Technology in Paris, and at the University of Edinburgh with a visit to Toulouse planned in the autumn. However, the highlight of the year was the IgNobel prize ceremony in Harvard for the work with Toshiyuki Nakagaki and his team on solving network problems with slime molds.
- 2009 was busy with conference presentations at the German Physical Society Annual Meeting in Dresden, a workshop on the Functioning and Failure of Adaptive Biological Networks at ZiF, Bielefeld, the BMS conference in Dundee, the Bioimaging symposium in Oxford and a seminar at Exeter. I also participated in the Technos International week in Japan, which was excellent.
- In 2008, studies on the fungal networks progressed well and we are developing strong links with physicists and mathematicians to analyse the network structure and function, with talks at the Bioinspired Complex Networks in Science and Technology conference in Dresden, Bioinspired Logistics in Ladenberg, and the inaugural session of the UK Fungal Network in Oxford. The year was finished off with a session at the Silicon Valley Networks Masterclass, an imaging workshop in Uppsala and the New Phytologist conference on the ecology of ectomycorrhizal fungi in Montpellier.
- In 2007, I gave a plenary talk at the RMS 8th International Botanical Microscopy in Salzburg on imaging nutrient transport acroos scales in fungal mycelia and we have started to distribute the software tools following the BMS meeting in Manchester. We hope to set up a web-site soon to present all the videos and download the software.
- In 2006 we completed several software tools to help analyse the fungal systems. It was fairly quiet on the conference front as ECCS ’06 was held in Oxford. I did manage a quick trip to Santa Barbara in December for the 5th International Conference on Ecological Informatics.
- In 2005 the link to complex systems and networks progressed well with presentations at the European Conference on Theoretical and Mathematical Biology in Dresden and at the Complex Adaptive Systems Seminar Series in Oxford. I also had a very useful trip to the Creative Research Institute at the University of Hokkaido, Japan to work with Toshiyuki Nakagaki on the infamous slime molds, and a three day session at Princeton discussing decision making and risk in foraging systems. 2005 also saw the 1st European Network meetings on Measuring and Modelling Complex Networks across Domains (MMCOMNET) and the Complex Systems meeting in Paris in November.
- In Feb 2004 I had a short trip to Scotland, giving talks at Aberdeen, Dundee and Edinburgh, as well as a Departmental seminar in Oxford. The Scottish theme continued with a paper at the Society for Experimental Biology annual meeting in Edinburgh, but then moved south to the British Mycological Society annual meeting in Nottingham in Sept.
- In 2003, I was invited to speak at several meetings including the Joint British and American Mycological Societies Congress in Asilomar and the 7th International Botanical Microscopy Conference in Lisbon. I also gave presentations at the 1st Complex Agent Based Dynamic Network meeting in Oxford and at Basidio 2003 in Wellesbourne.
- December 2002: I visited Nice as part of a British Council Alliance award studying the role of glutathione in root nodule initiation and development with Dr Piere Frendo and Dr Judith Harrison.
- In July 2002 we presented some of the fungal imaging work as The Underground Pulse at the Royal Society Summer Exhibition. Dr Tlalka also presented this work at the 7th International Mycological Congress, Oslo.
- April 2002: Conference paper at the Society for Experimental Biology Meeting in Swansea.
- Feb 2002: Invited speaker at the Australian Conference on Electron Microscopy (ACEM) in Adelaide combined with a visit to discuss fungal vacuole dynamics with Prof. Anne Ashford and Bill Allaway at the University of New South Wales (Sydney).
