Project description:Illumina HiSeq technology was used to generate mRNA profiles from Tuber magnatum truffles, free-living mycelium and oak mycorrhizal root tips. Paired-end reads of 100 bp were generated and aligned to Tuber magnatum reference transcripts using CLC Genomics Workbench 9.

Project description:An in vivo and in vitro potato tuber development gene expression study. For in vitro tuber development expression analysis, RNA was isolated from in vitro microtubers at 2, 5, 10, 20 and 30 days following observed tuber induction. Two microtuber populations were used as biological replicates for the developmental stages. The RNA from all developmental stages was pooled to generate the reference samples. Ten microarray hybridizations were performed. For in vivo tuber development expression analysis, RNA was isolated from tubers growing in growth chamber conditions. Tissues were divided into six group, according to developmental size: stolon (no tuber formation), 1-5 mm tubers, 6-10 mm tubers, 11-15 mm tubers, 16-25 mm tubers, and 26-35 mm tubers. Two biological replicates of ten plants each were grown sequentially in the same growth chamber. The RNA from all developmental stages was pooled to generate the reference samples. Twelve microarray hybridizations were performed. For all experiments, the RNA was labeled using the indirect labeling method with random hexamer primers. Amplified cRNA was used as labeling template for stolons. Total RNA was used as labeling template in all other labeling reactions.

Project description:We report the application of RNA- sequencing technology for high-throughput profiling of histone modifications in mammalian cellsor identification of expressed genes upon infection by Spongospora subterranea. Using RNA-sequencing (RNA-seq), 2058 differentially expressed genes (DEGs) were identified from two potato cultivars (tolerant and susceptible) in response to Sss infection. Analysis of the expression patterns of ten selected defense-response genes was carried out at two different stages of tuber growth using RT-qPCR to validate the RNA-seq data. Several defense related genes showed contrasting expression patterns between the tolerant and susceptible cultivars, including marker genes involved in the salicylic acid hormonal response pathway (StMRNA, StUDP and StWRKY6). Induction of six defense related genes (StWRKY6, StTOSB, StSN2, StLOX, StUDP and StSN1) persisted until harvest of the tubers, while three other genes (StNBS, StMRNA and StPRF) were highly up-regulated during the initial stages of disease development. The results of this study suggested that the tolerant potato cultivar employs quantitative resistance and salicylic acid pathway hormonal responses against tuber infection by Sss. The identified genes have the potential to be used in the development of molecular markers for selection of powdery scab resistant potato lines in marker assisted breeding programs.
