Summary:

Current Research Interests.

 My group investigates soil microbial ecology in agricultural systems focusing both on rhizosphere interactions and also considering wider soil functions that support plant health and productivity including nitrogen cycling. We use molecular approaches to link population size and diversity with relevant functions, increasingly by using metagenomic approaches. The Rothamsted long-term field experiments provide an invaluable resource for such studies and we have several international collaborations to expand the scope of this research, including metagenomic library construction, high throughput sequencing and the use of microarrays. Areas of interest extend from denitrification and nitrification in soil, to interactions between the root colonizing bacteria and fungi, especially those with potential to control plant parasitic nematodes. We also have an interest in the genetic structure of soil microbial populations, in particular the distribution of genetic elements within different constituent populations.

Recent findings:

  • When soil that was originally permanent grassland is deprived of plant inputs for > 50 years by frequent tilling, with a consequent reduction of soil carbon, soil fauna and microbial abundance, the genetic diversity of microbial communities remains at a similar level to that in the original grassland. We speculate that we are observing the underlying diversity of bacterial communities that survive on recalcitrant C, revealed when the more abundant phyla that rely on simple plant-derived carbohydrates are diminished.
  • Metagenomic seqeuqnce data from these soils indicates differences in community composition.
  • Denitrification rates may depend on soil moisture, carbon and nitrogen content but the genetic diversity of denitrifying bacteria is similar in arable soils under different long-term fertilizer inputs. However there are distinct differences when cultivation ceases and soils revert to grass or woodland.
  • The population structure of ammonia oxidizing bacteria differs in plots receiving different long-term N additions, and that a growth response to NH4 can be seen six weeks after fertilizer addition, although nitrification starts rapidly and is not directly proportional to population size.
  • There is no clear difference in rhizosphere populations of potatoes with an anti-fungal root-expressed transgene compared to parental lines and another potato cultivar, whereas there were distinct differences between plants +/- AM fungi.
  • Microscale sampling of bacteria on roots reveals that communities are less abundant at the apex compared to basal regions of the root, that there is less genetic diversity on the root compared to bulk soil, and that microcolony density is inversely correlated with root pH (joint research with Tony Miller)
  • The nematophagous fungus Pochonia chlamydosporia shows genetic diversity depending on geographic and host nematode origin, and biotypes show host preference associated with polymorphism in a serine protease implicated in infection of nematode eggs. However, saprotrophic competitiveness may not relate to parasitic activity in the rhizosphere of nematode infected plants.
  • Pochonia chlamydosporia genes associated with nematode egg infection, including the serine protease gene vcp1, show differential expression depending on nutrient availability, indicating that the carbon and nitrogen content of soil amendments may influence parasitic activity of the fungus.
