Project description:We used the Illumina RNAseq approach to study the effects of acute exposure to elevated CO2 on gene expression in primary polyps of Acropora millepora Examination of transcriptome in Acropora millepora primary polyps at 380, 750 and 1000 ppm CO2 after 3 days exposure
Project description:We compared the effect of acute (Moya et al 2012) and chronic exposure to elevated pCO2 on gene expression in primary polyps of Acropora millepora Examination of transcriptome in Acropora millepora primary polyps at 380 and 750 ppm CO2 (air) after 9 days exposure

Project description:Casuarina glauca belongs to a family of angiosperms called actinorhizal plants because they can develop nitrogen-fixing nodules in association with the soil bacteria Frankia. The aim of this transcriptomic study was to get a global view of the plant symbiotic genetic program and to identify new key plant genes that control nodulation during symbiosis in C. glauca. Symbiosis between C. glauca and Frankia was obtained after inoculation of young plant with a concentrated culture of the bacteria. Inoculation was performed in a medium depleted in nitrogen which favors the induction of nitrogen fixing symbiosis. For this study we considered two stages of symbiosis: - an early stage where inoculated roots were harvested 7 days after inoculation with the bacteria and compared to two controls (non-inoculated roots grown with or without nitrogen and harvested at the same time) - a late stage where nodules (nitrogen-fixing specific organs) were harvested 21 days after inoculation and compared to non-inoculated roots harvested on the day of inoculation (which is our reference time 0d). Three biological replicates were used for each condition. Microarrays were designed by Imaxio (Clermont Ferrand, France ; http://www.imaxio.com/index.php) which has been accredited by Agilent Technologies (Palo Alto, CA, USA; http://www.home.agilent.com/agilent/home.jspx) as a certified service provider for microarray technologies. Based on 14327 annotated unigenes for C. glauca, 60mers probes were designed using eArray software (1 probe per unigene) and custom 8 x 15K Oligo Microarrays were manufactured by Agilent.
Project description:The goal is to look at changes in the pattern of expression of the xylem transcriptome through the growth season in two spruces (Picea glauca and Picea abies).
