Experimental models in the Raymond lab include (from left to right): diamondback moth, our work horse of in vivo microbial experimental evolution; cabbage looper larva – which supply model gut communities for evolution of antibiotic resistance; tomato seedlings - model systems for community ecology of root symbionts, and finally the Titan Arum in whic we are also studying plant-microbe symbioses.

I am an experimental evolutionary ecologist who works with insects, plants, bacterial pathogens and symbionts. Much of my research focuses on virulence and resistance, particularly the evolution of virulence in parasites and symbionts, the evolution of resistance to the biological control agent Bacillus thruringiensis and, increasingly, the evolution of resistance to antibiotics. I have also worked on the basic ecology of biocontrol agents and beneficial bacteria, such as B. thuringiensis, rhizobacteria and insect baculoviruses. As well as testing and advancing fundamental ideas, I am particularly interested in applying theory to real world problems such as improving the efficacy and sustainability of biocontrol tools or managing the evolution of resistance. My work ranges from the laboratory to the field and includes a number of in vivo and in vitro experimental evolution systems that have been developed by my group.

Diverse root bacteria extracted from crop plants for use in competition and community structure experiments.

Evolutionary ecology of virulence in Bacillus thruringiensis - including cooperation & conflict in the field (Raymond et al. 2012, Science) as well as explorations of evolutionary genomics in collaboration with the Sheppard lab (Meric et al Mol. Ecology in press) and Prof Ming Sun at Huazhong Agricultural University (Zheng et al. 2017, mBio)

White antibiotic susceptible ‘satellite’ colonies surrounding blue antibiotic resistant Escherichia coli. The resistant colonies produce beta-lactamase that removes antibiotic (ampicillin) from the growth medium. Susceptible cells that go through a period of dormancy can escape the effects of antibiotic and begin growing after resistant bacteria have produced antibioitic free space (from Medaney et al 2015, ISME).

Research

Research interests

Cooperation and the evolution of virulence. The idea that kin selection might maintain group beneficial traits in microbes has revolutionized how we see virulence in bacteria, particularly virulence that is dependent on the extracellular export of proteins. My group has been one of the first to explore the implications of this theory in naturalistic host pathogen interactions, rather than in highly controlled artificial media.  While social interactions seem to be more important for some virulence factors than others, these ideas have been invaluable for understanding investment in virulence in B. thuringiensis and in other biocontrol agents such as entomopathogenic nematodes. Ongoing research projects are investigating whether how can apply our understanding of social interactions to shape the evolution of biocontrol agents in the laboratory and have resulted in a recent patent application.

Evolution and ecology of symbionts. Many bacteria switch between pathogenic, commensal and mutualistic lifestyles very readily over evolutionary timescales.  I am interested in the evolutionary ecology of selection for virulence in symbionts. We are also investigating plant-symbiont ecology and evolutionary ecology in a number of systems, including model crop species as well as the Titan Arum, Amorphophallus titanum, we have been exploring how environmental factors shaping the make-up of symbiont communities and whether this understanding can better shape our use of beneficial bacteria.

Evolution of resistance to biopesticides and GM crops. Applied as organic microbial pesticide, or as Cry toxins in GM crops, B. thuringiensis provides an exceptionally environmentally safe form of pest management, with no harmful effects on non-target organisms. It is therefore a technology worth preserving. This chiefly requires managing the evolution of resistance in target pests. Previously, I have explored how the fitness costs associated with resistance to B. thuringiensis could be manipulated to reduce the rate of evolution of resistance, as well as the value of biopesticide combinations in combating resistance. Current collaborations have investigated the genetic mechanisms of resistance in various Lepidopteran pests, and how insect behavior in the field might explain the very rapid evolution of resistance seen in some species. Recent research (with Oxitec and the University of Oxford) is investigating how the release of self-limiting genetically modified insects might be used as a tool to slow the evolution of resistance in diamondback moth, Plutella xylostella

Evolution of resistance to antibiotics. Resistance management is widely practiced in insect pest control but has had only a few successes in important human pathogens (mostly for the treatment of TB and HIV). Solutions to the current crisis in antibiotic resistance require imaginative solutions and better data. I am interested in applying many of lessons learnt in pesticide resistance management to the context of antibiotic resistance and have been developing a novel model experimental system (using Enterobacter cloacae in Lepidoptera) to test various ideas, including how best to use bacteriophage to combat the evolution of resistance.  

Biology and ecology of Bacillus thuringiensis. This bacterium is the world’s biggest selling microbial pesticide and supplies the key active proteins (Cry toxins) that are expressed in genetically modified insect resistant crops.   Despite its applied importance, the fundamental biology and ecology of this bacterium has been largely neglected, although this has broad implications for the biosafety of this organism and understanding how it kills its hosts. I am interested in how selection has led to the specialized production of large quantities of virulence factors and how this pathogen reproduces in the field in the absence of substantial epidemics. Ongoing interests include exploring the evolutionary relationship between B. thuringiensis and its complement of plasmids as well as evolutionary genomics and the importance of good science for understanding the biological safety of microbes in plant husbandry.
