Research Aims
RETURN TO TOP

The Big Question

To understand the mechanisms controlling colonisation of roots by beneficial arbuscular mycorrhizal fungi (AMF) and the cellular/molecular bases underlying the fungal contribution to plant nutrition and growth. Ultimately we aim to determine the significance of diversity in function among different host plant/arbuscular mycorrhizal fungus (AMF) combinations with respect to plant nutrition, performance and competitive interactions

The Short-term goals

  • To clone and characterise the gene (Rmc) which when mutated results in reduced mycorrhizal colonisation in tomato (with Dr Susan Barker, UWA)
  • To determine if the major variations in the AM fungal contributions to plant P uptake we have recently found are related to differential expression of mycorrhiza-specific P transporters in plant roots
  • To extend investigation of the contribution of AMF to nutrition of plants that do not respond to colonisation in terms of whole plant nutrient uptake or growth. We have recently shown that one non-responsive species can received 100% of its P via AMF. The questions are now how widespread this is and whether uptake of nutrients other than P may be similarly influenced by the AMF.
Research Interests

  • Mycorrhizal symbioses
  • Plant nutrition, particularly with respect to the transport of nutrients between fungal and plant partners in mycorrhizas.
  • Diversity of structure and function of mycorrhizas in different plant/fungus combinations with respect to physiology and molecular biology of nutrient transfer and effects on agricultural and ecological performance of both plants and fungi.

A statement on the most significant contributions to this research field
RETURN TO TOP

I have a high international reputation in the field of mycorrhizal symbiosis and I contribute in-depth knowledge and expertise on structure, development and function of arbuscular mycorrhizas to the team making this application. I am co-author (with Professor D.J. Read, FRS) of the pre-eminent and extensively cited research text on mycorrhizas (Mycorrhizal Symbiosis Ed 2. S.E. Smith and D.J. Read, 1997. Academic Press); a third edition is sought by the publishers. I have contributed about 45 invited reviews and book chapters (including Biological Reviews; Annual Reviews of Plant Physiology and Plant Molecular Biology; Tansley Reviews in New Phytologist [2]) and ~135 refereed articles in international journals. I have taken an integrated approach to research. This has involved strong collaborations and the ability to establish and foster these is one of my significant abilities and contributions. On arbuscular mycorrhizas I have: 1) introduced novel methods to study processes involved fungal colonisation, including the 3D structure, longevity and characteristics of the intraradical phases involved in nutrient transfer; 2) contributed to understanding physiological bases for the growth responses of plants to colonisation; 3) been among the first to utilise molecular biological techniques to probe the plant/fungus interactions, helping to overcome difficulties posed by close spatial interdigitation of the symbionts and the unculturable nature of the fungi; 4) with Dr Susan Barker isolated the first non-legume mycorrhiza-defective mutant, appreciating the potential of mutants to advance our knowledge of the genetic and physiological interactions between the symbionts; 5) recognised the importance of functional and structural diversity in the symbioses between different species of fungi and host plants (including Arum - and Paris -AM), investigating these at cellular, whole plant and ecological levels, including the development and use of molecular detection methods in the ecology of mycorrhizal fungi.
