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. 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:Arbuscular mycorrhizal symbiosis is a predominant relationship between plant and arbuscular mycorrhizal fungi. To idendify arbuscular mycorrhiza responsive miRNAs, small RNA libraries were constructed in tomato roots colonized with Rhizophagus irregularis and without Rhizophagus irregularis. We identify miRNAs in tomato roots and provide a new profile of tomato miRNAs. And we found that some miRNAs were responsive to arbuscular mycorrhiza by comparing miRNAs in treatment with that in control.

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: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).

Project description:To investigate the involvement of arbuscular mycorrhizal symbiosis in the moleular regulation in foxtail millet roots and the effects of genetic variation on AMS-mediated molecular regulation, we isolated total RNA from the roots of 3 different landraces for comprehensive transcriptomic analysis. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different landraces (Hanevalval, TT8, ICE36) after 6-week mock or arbuscular mycorrhizal fungi treatments.

Project description:Abstract: A large part of the nitrogen in forest soils is found in recalcitrant organic matter-protein complexes. Ectomycorrhizal fungi are thought to have a key role in the decomposition and mobilization of nitrogen from such complexes. The knowledge on the functional mechanisms of these processes, and how they are regulated by carbon from the host plant and the availability of more easily available forms of nitrogen sources are limited. We used spectroscopic analyses and transcriptome profiling to examine how the presence/absence of glucose and ammonium regulates the decomposition and mobilization of nitrogen from litter material by the ectomycorrhizal fungus Paxillus involutus. Amendments of glucose triggered the assimilation of nitrogen and the decomposition of the litter material. Concomitantly, the expression of genes encoding enzymes involved in oxidative (i.e. Fenton chemistry) degradation of polysaccharides and polyphenols, peptidases, nitrogen transporters and enzymes in pathways of the nitrogen and carbon metabolism were upregulated in concert. Addition of ammonium had minute effects on both the expression of transcripts and decomposition of litter material, and only when glucose was present. Based on the spectroscopic analyses, three major types of chemical modifications of the litter material were observed. Each of them was correlated with the expression of specific sets of genes encoding extracellular enzymes. Our data suggests that the expression of the decomposition and nitrogen assimilation machinery of ectomycorrhizal fungi can be firmly regulated by the host carbon supply, i.e. priming, and that the availability of inorganic nitrogen as such has limited effects on the saprotrophic activities.
