Project name: Medicago truncatula

Description: Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel cell-type specific gene expression during early stages of Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on laser-microdissected cells. We used Medicago GeneChips to detail the cell-type specific programme of gene expression in early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these stages.Overall design: Medicago truncatula Gaertn ‘Jemalong’ genotype A17 plantlets were grown in the climate chamber. Plants grown for the collection appressorial root areas (APP) and the corresponding non-appressorial root areas (NAP) were mycorrhized after 3 weeks and roots were harvested at 5-6 dpi.
