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 mycorrhizal (AM) symbiosis that associates roots of most land plants with soilborne fungi (Glomeromycota), is characterized by reciprocal nutritional benefits. Fungal colonization of plant roots induces massive changes in cortical cells where the fungus differentiates an arbuscule, which drives proliferation of the plasma membrane, and the de novo synthesis of the periarbuscular membrane. Despite the recognized importance of membrane proteins in sustaining AM symbiosis, the root microsomal proteome elicited upon mycorrhiza still remains to be explored. In this study, we first examined the qualitative composition of the root membrane proteome of Medicago truncatula after microsome enrichment and subsequent in depth analysis by GeLC-MS/MS. The results obtained highlighted the identification of 1226 root membrane protein candidates whose cellular and functional classifications predispose plastids and protein synthesis as prevalent organelle and function, respectively. Changes at the protein abundance level between the membrane proteomes of mycorrhizal and nonmycorrhizal roots were further monitored by spectral counting, which retrieved a total of 97 proteins that displayed a differential accumulation upon AM symbiosis. Besides the canonical markers of the periarbuscular membrane, new candidates supporting the importance of membrane trafficking events during mycorrhiza establishment/functioning were identified, including flotillin-like proteins.

Project description:Most vascular flowering plants have the ability to form mutualistic associations with soil fungi from the Glomeromycota. The resulting symbiosis is called an arbuscular mycorrhiza and they are widespread in terrestrial ecosystems throughout the world. Significant alteration occurs at physiological and molecular levels in both symbionts. To gain a better understanding of the AM symbiosis, we use a 16000 feature oligonucleotide based array to examine gene expression in an arbuscular mycorrhizal symbioses, M. truncatula/Gigaspora gigantea. Keywords: Medicago truncatula, Mycorrhizal, Gigaspora gigantea, microarray profiling

Project description:The mutualistic arbuscular mycorrhizal (AM) symbiosis arose in land plants more than 450 million years ago. This symbiosis is still widely found across major land plant lineages, including bryophytes. Despite its broad taxonomic distribution, little is known about the molecular components underpinning symbiosis outside of flowering plants. Here, we demonstrate that a broad AM genetic programme is conserved amongst land plants. In this study, we characterised the dynamic response of the liverwort Marchantia paleacea to Rhizophagus irregularis colonization by time-resolved transcriptomics across three stages of symbiosis. Comparative analysis of transcriptional responses to symbiosis in the liverwort M. paleacea and the legume Medicago truncatula further revealed evolutionarily conserved expression patterns for genes underpinning pre-symbiotic signalling, intracellular colonization and nutrient exchange. This study demonstrates that the genetic machinery regulating key aspects of symbiosis in plant hosts is largely conserved and coregulated across land plants.

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:Plant species posses a special set of genes functional only in arbuscular mycorrhizal symbiosis. So, the model plant Medicago truncatula (Jemalong 5) was used for transcriptome comparative analysis while infected with compatible rhizobia Sinorhizobium meliloti (strain 10) and with or without arbuscular mycorrhizal fungus Rhizophagus irregularis (SYM5). Whole shoot and whole root were used for RNA isolation and processed via one of the European certified Affymetrix core labs (http://core.img.cas.cz).

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:The increased urban pressures are often associated with specialization of microbial communities. Microbial communities being a critical player in the geochemical processes, makes it important to identify key environmental parameters that influence the community structure and its function.In this proect we study the influence of land use type and environmental parameters on the structure and function of microbial communities. The present study was conducted in an urban catchment, where the metal and pollutants levels are under allowable limits. The overall goal of this study is to understand the role of engineered physicochemical environment on the structure and function of microbial communities in urban storm-water canals. Water and sediment samples were collected after a rain event from Sungei Ulu Pandan watershed of >25km2, which has two major land use types: Residential and industrial. Samples were analyzed for physicochemical variables and microbial community structure and composition. Functional gene abundance was determined using GeoChip.
