Project description:Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel gene expression during early stages of Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on mycorrhizal root fragments enriched for early fungal infection stages. We used Medicago GeneChips to detail the global programme of gene expression in response to early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these early stages.
Project description:Illumina HiSeq technology was used to generate mRNA profiles from Helianthemum almeriense in three different conditions: non-mycorrhizal plant, well-watered mycorrhizal plant and drought-stressed mycorrhizal plant. Paired-end reads of 75 bp were generated and aligned to a de novo transcriptome assembly from H. almeriense, which was performed using Megahit version 1.1.3 and transcripts from each condition were mapped onto the de novo transcriptome with Bowtie2 version 2.3.0.
Project description:Illumina HiSeq technology was used to generate mRNA profiles from Terfezia claveryi in three different conditions: free living mycellium, well-watered mycorrhizal plant and drought-stressed mycorrhizal plant. Paired-end reads of 75 bp were generated and aligned to Terfezia claveryi reference transcripts using CLC Genomics Workbench 11.

We used Medicago GeneChips to detail the global programme of gene expression in response to early stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these early stages. Medicago truncatula GFP-HDEL hairy roots (genotypes A17 and DMI3) were grown in vertically-oriented petri dishes, incubated at 26M-BM-0C and inoculated with 8 Gigaspora margarita spores, which were positioned between the lateral roots. G.margarita spores germinated in 2 to 4 days. Hyphopodia were observed after 5-6 days. Root fragments which reacted to the fungal contact were collected and frozen. Non-inoculated control root fragments were harvested at a comparable age.
