Abstract: | The arbuscular mycorrhizal (AM) symbiosis formed between plant roots and fungi is one of the most widespread symbiotic associations found in plants, yet our understanding of events underlying its development are limited. The recent integration of biochemical, molecular and genetic approaches into analyses of the symbiosis is providing new insights into various aspects of its development. In the past year there have been advances in our understanding of the signals required for the formation of appressoria, the molecular changes in the root in response to colonisation, and components of the signal transduction pathways common to both the AM and Rhizobium symbioses. |
