Affy_med_2011_14-Transcriptomic analysis of roots of WT (A17) Medicago truncatula plants and of a hypermycorrhizal mutant (B9) grown on limiting (P/10) or non-limiting phosphate (P2).

ABSTRACT: affy_med_2011_14 - affy_med_2011_14 - -In natural ecosystems most terrestrial plants form arbuscular mycorrhiza (AM), mutualistic symbioses with soil fungi belonging to the order Glomeromycota. This symbiosis takes place when phosphate is limiting and enables the plant to acquire nutrients (in particular phosphate) in exchange of carbon provided to the fungus A hypermycorrhizal mutant B9 was identified (Morandi et al. Mycorrhiza (2009) 19: 435) which displayed higher root colonization by Glomus intraradices. This phenotype could be linked to a defect in phosphate sensing or transport. We have undertaken the analysis of the root transcriptome of both WT and mutant plants grown on limiting or non-limiting phosphate to determine which processes are affected in the hypermycorrhizal mutant.-- R
