identifying and describing putative gene sequences within the genome sequence. Symbioses with soil microorganisms Researcher Toby Kiers of VU University Amsterdam and associates used M. truncatula to study symbioses between plants and fungi – and to see whether the partners in the relationship could distinguish between good and bad traders/suppliers. By using labeled carbon to track the source of nutrient flowing through the arbuscular mycorrhizal system, the researchers have proven that the plants had indeed given more carbon to the more generous fungus species. By restricting the amount of carbon the plants gave to the fungus, the researchers also demonstrated that the fungi did pass along more of their phosphorus to the more generous plants. Proteome Proteomic investigation by mass spectrometry has been performed by Wienkoop et al 2004 and Larrainzar et al 2007.
