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.

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.

Project description:Dispersal of arbuscular mycorrhizal fungi
| PRJNA783165 | ENA
Project description:Many of the microorganisms that are normally present in the soil, actually inhabit the rhizosphere and interact with plants. Those plant–microorganisms interactions may be beneficial or harmful. Among the first are the arbuscular mycorrhizal fungi (AMF). These soil fungi have been reported to improve plant resistance/tolerance to pests and diseases. On the other hand, soilborne pathogens represent a threat to agriculture generating important yield losses, depending upon the pathogen and the crop. One example is the “Sudden Death Syndrome” (SDS), a severe disease in soybean (Glycine max (L.) Merr) caused by a complex of at least four species of Fusarium sp., among which Fusarium virguliforme and F. tuccumaniae are the most prevalent in Argentina. This study provides, under strict in vitro culture conditions, a global analysis of transcript modifications in mycorrhizal and non-mycorrhizal soybean root associated with F. virguliforme inoculation. Microarray results showed qualitative and quantitative changes in the expression of defense-related genes in mycorrhizal soybean, suggesting that AMF are good candidates for sustainable plant protection against F. virguliforme.

Project description:Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel gene expression in Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on whole mycorrhizal roots. We used GeneChips to detail the global programme of gene expression in response to colonization by arbuscular mycorrhizal fungi and in response to a treatment with phosphate and identified genes differentially expressed during this process.

To unravel gene expression in Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on whole mycorrhizal roots. We used GeneChips to detail the global programme of gene expression in response to colonization by arbuscular mycorrhizal fungi and in response to a treatment with phosphate and identified genes differentially expressed during this process. Medicago truncatula roots were harvested at 28 days post inoculation with the two different arbuscular mycorrhizal fungi Glomus intraradices (Gi-Myc) and Glomus mosseae (Gm-Myc) under low phosphate conditions (20 µM phosphate) or after a 28 days treatment with 2 mM phosphate in the absence of arbuscular mycorrhizal fungi (2mM-P). As a control, uninfected roots grown under low phosphate conditions (20 µM phosphate) were used (20miM-P). Three biological replicates consisting of pools of five roots were used for RNA extraction and hybridization on Affymetrix GeneChips.

Project description:The crop species Solanum lycopersicum establishes a beneficial root- symbiosis with the widespread group of arbuscular mycorrhizal (AM) fungi. The mycorrhiza establishment leads to a modulation of the plant gene expression which is not restricted to the root compartment but spreads at the organism-wide level. To understand the systemic effect of the fungal presence on the tomato fruit, we performed global transcriptome profiling through RNA-Seq analysis on Moneymaker tomato fruits sampled at the turning ripening stage. Gene expression data were obtained from fruits sampled at 55 days after flowering. Fruits were collected from Funneliformis mosseae colonized plants and from control plants which were fertilized in order to avoid responses related to nutrient deficiency.

Project description:affy_ams_maize - aafy_ams_maize - Main objectives of this study: - role of plant cell wall during AM symbiosis - regulation pattern during AM symbiosis - understanding of the original mycorrhizal phenotype of bm4 - search of candidate-genes to study AM symbiosis-After 7 days in phytochambers, plantlets were transplanted in 2L of humidified bedrock with 3000 spores for inoculation conditions or without spore for mock conditions then plants have grown in greenhouse. Maize roots have been sampled 7 weeks post-inoculation and freezed in liquid nitrogen then stocked at -80°C. Total RNA was isolated from frozen root tissue by using the RNeasy Plant Mini Kit (Qiagen) following the manufacturer’s instructions. Keywords: treated vs untreated comparison
