Project description:We have used deep sequencing of small RNAs from nodules and root apexes of the model legume Medicago truncatula, to identify 113 novel candidate miRNAs. These miRNAs (legume or Mt-specific) are encoded by 278 putative hairpin precursors in the M. truncatula genome. Several miRNAs are differentially expressed in nodules and root tips and large variety of targets could be predicted for these genes. Specific miRNA isoforms showed contrasting expression patterns in these tissues Keywords: Transcriptome analysis 3 samples examined: nodules, root tips, and root tips + NaCl

Project description:The purpose of the present study is to determine the effect of Phosphorus deficiency on gene expression level using microarray analysis to identify genes responsible for root hair development. Phosphorus deficiency induced the formation of root hairs to explore a greater soil volume but molecular mechanisms were unknown. Therefore, microarray experiments were performed using root tips of Brassica carinata cultivars Bale and Bacho, respectively differing in root hair length during Phosphorus deficiency. Experimental design was carried out in nutrient solution in a climate chamber with controlled environmental conditions (20°C, 16h day/8h night cycle, 70% relative humidity) in a randomized design. 25 root tips from 10 day old seedlings grown without Phosphorus of 1cm length were harvested and immediately frozen in liquid nitrogen. Gene expression analyses were performed

Gene expression analyses were performed Results from xy microarrays are summarized in this study. The samples originate from roots of cultivars Bale and Bacho grown in Phosphorus deficient conditions. Microarrays were hybridized with Cy3 and Cy5 labeled cDNA from Bale and Bacho both during Phosphorus deficiency using a dye swap approach

Project description:The aim of this study was to determine the changes in gene expression of rice root tips when they came in to contact with a hard layer (60% wax layer). Three categories of root tips were sampled; tips before the hard layer, tips that had come into contact with the hard layer and root tips which had buckled after coming into contact with the hard layer. Two genotypes (Azucena and Bala) that vary in there ability to penetrate a hard layer were selected for a genotype comparison of gene expression at the hard layer. Keywords: Genotype comparison, root impedance response

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Hebeloma cylindrosporum ectomycorrhizal root tips compared to free-living mycelium . Ectomycorrhizal root tips were harvested after 6 months and used for RNA extraction. Reads of 100 bp were generated and aligned to Hebeloma cylindrosporum transcripts (http://genome.jgi-psf.org/Hebcy2) using CLC Genomics Workbench 6. mRNA profiles from Hebeloma cylindrosporum ectomycorrhizal root tips and free-living mycelium were generated by Illumina HiSeq2000 sequencing (100bp). Ttwo biological replicates were sequenced for mycorrhizal and mycelium samples.

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Amanita muscaria ectomycorrhizal root tips compared to free-living mycelium . Ectomycorrhizal root tips and control mycelium were harvested after 6 weeks and used for RNA extraction. Reads of 150 bp were generated and aligned to Amanita muscaria transcripts (http://genome.jgi-psf.org/Amamu1) using CLC Genomics Workbench 7. mRNA profiles from Amanita muscaria ectomycorrhizal root tips and free-living mycelium were generated by Illumina HiSeq2000 sequencing (150bp). Two biological replicates were sequenced for mycorrhizal and mycelium samples.
