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:The recent release of a large number of genomes from ectomycorrhizal, orchid mycorrhizal and root endophytic fungi have provided deep insight into fungal lifestyle-associated genomic adaptation. Comparative analyses of symbiotic fungal taxa showed that similar outcomes of interactions in distant related root symbioses are examples of convergent evolution. The order Sebacinales represents a sister group to the Agaricomycetes (Basidiomycota) that is comprised of ectomycorrhizal, ericoid-, orchid- mycorrhizal, root endophytic fungi and saprotrophs (Oberwinkler et al., 2013). Sebacinoid taxa are widely distributed from arctic to temperate to tropical ecosystems and are among the most common and species-rich groups of ECM, OM and endophytic fungi (Tedersoo et al., 2012, Tedersoo et al., 2010, Oberwinkler et al., 2013). The root endophyte Piriformospora indica and the orchid mycorrhizal fungus S. vermifera (MAFF 305830) are non-obligate root symbionts which were shown to be able to interact with many different experimental hosts, including the non-mycorrhizal plant Arabidopsis thaliana. These two fungi display similar colonization strategies in barley and in Arabidopsis and the ability to establish beneficial interactions with different hosts (Deshmukh et al., 2006). Colonization of the roots by P. indica and S. vermifera results in enhanced seed germination and biomass production as well as increased resistance against biotic and abiotic stresses in its experimental hosts, including various members of the Brassicaceae family, barley, Nicotiana attenuata and switchgrass (Ghimire, 2011, Ghimire et al., 2009, Ghimire et al., 2011, Waller et al., 2008, Barazani et al., 2007, Deshmukh et al., 2006). Microarray experiments were performed to identify and characterize conserved sebacinoid genes as key determinants in the Sebacinales symbioses.

Project 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. Medicago truncatula Gaertn M-bM-^@M-^XJemalongM-bM-^@M-^Y 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.

Project 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 late 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 late stages of colonization by arbuscular mycorrhizal fungi and identified genes differentially expressed during these stages. Medicago truncatula Gaertn M-bM-^@M-^XJemalongM-bM-^@M-^Y genotype A17 plantlets were grown in the climate chamber. Plants grown for the collection of root cortical cells containing arbuscules (ARB), root cortical cells from mycorrhizal roots (CMR), and root epidermal cells from mycorrhizal roots (EPI) were mycorrhized after 2 weeks with Glomus intraradices and mycorrhizal roots were harvested at around 21 days post inoculation (dpi).

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. 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:Endophytic fungi are root-inhabiting fungi that can promote plant growth in a variety of ways. They can directly stimulate plant growth by producing phytohormones, such as auxin and gibberellins. They can also indirectly promote plant growth by helping plants to acquire nutrients, such as nitrogen and phosphorus, and by protecting plants from pests and pathogens.In this study, we used a proteomic approach to identify the proteins that are expressed in rice plants after they are treated with endophytic fungi. We found that the treatment with endophytic fungi resulted in the expression of a number of proteins involved in plant growth, nutrient acquisition, and defense. These results suggest that endophytic fungi can promote plant growth and improve plant resilience to stress.

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.
