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 and control mycelium were harvested after 3 weeks and used for RNA extraction. Reads of 150 bp were generated and aligned to Hebeloma cylindrosporum transcripts (http://genome.jgi-psf.org/Hebcy2) using CLC Genomics Workbench 7. mRNA profiles from Hebeloma cylindrosporum ectomycorrhizal root tips and free-living mycelium were generated by Illumina HiSeq2000 sequencing (150bp). Three biological replicates were sequenced for mycorrhizal and mycelium samples.

Gibberellin (GA) Treatment of Arabidopsis Root Tips

Project description:The plant hormone gibberellin (GA) represents an important regulator of growth and development. Early transcriptional events controlled by GA are not well characterised. Previous microarray studies have identified genes responsive to GA treatment in the whole seedling. The whole seedling represents many tissues where subtle effects of GA treatment in specific tissues may be masked. When treated with GA, an effect on the growth rate of roots was observed. More specifically, the shorter root of a GA-deficient plant can be rescued to wild-type length by the application of GA. This experiment was designed to identify GA-regulated genes in the root tips of Arabidopsis. The use of a GA-deficient mutant provides a greater potential to identify genes responding to GA treatment. Root tips are ideally suited for the quick uptake of the hormone treatment. There will be two biological replicates which will each consist of a control treatment at 0 minutes and 2 hours, as well as the experimental GA-treated 2 hour time point. This system provides an opportunity to compare gene expression between treated and non-treated root tips and allow the identification of early GA-responsive genes.

Laccaria bicolor gene expression in different tissues and with different host trees

Project description:Laccaria bicolor transcript profiles of different tissues and mycorrhizal root tips from different host trees were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Laccaria bicolor genome sequence version 1. One goal was to compare gene expression profiles from ectomycorrhizal root tips with different host plants.

Gene expression of rice root tips before, at and buckled by a hard layer in two rice varieties

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
