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/G. intraradices. Keywords: Medicago truncatula, Mycorrhizal, Glomus intraradices, microarray profiling
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. Although the physical interaction between the symbionts occurs in the root cortex, the symbiosis impacts the physiology of the whole plant. To gain a better understanding of the AM symbiosis, we have used the 16000 feature array to examine gene expression in the leaves of mycorrhizal plants to explore the transcriptional changes that are triggered systemically as a result of the AM symbiosis. Keywords: Medicago truncatula, Mycorrhizal, systemic regulation, microarray profiling

Project description:12plex_medicago_2014_02 - nar nodule vs root transcriptome - which are the genes differentially expressed in alfalfa spontaneous (non rhizobium-infected) nodules vs. control roots? - biological material: aeroponically grown cuttings of a Medicago sativa (alfalfa) accession that produces empty nodules when nitrogen-starved. Samples for transcriptome comparison: isolated NAR nodules (10 days post N-starvation) vs. roots of the same plants (pools of 3 roots).
