title: High-Throughput  Sequencing on mRNA from Rojo Pasion Apricot
organism: Prunus armeniaca var. armeniaca
description: First results apricot RNA-seq performed in the Plum pox virus (PPV)resistant genotype Rojo Pasion in collaboration with the Ultrasequencing Unit of the Centre for Genomic Regulation of Barcelona (Spain) (http://www.crg.es) showed the high number of reads (more than 20 million)and their good quality (only 2% of the reads have been discarded). In addition, 72.3% of these reads have been aligned to a single location to the reference peach genome (v1.0) (http://www.rosaceae.org/peach/genome) with 0, 1 or 2 mismatches. These alignement results confirmed the high levels of synteny between Prunus transcriptomes, also evidenced for Prunus genomes, and the utility of the peach genome as reference in first RNA-Seq studies in other Prunus species. Differential analysis of this RNA-Seq data is being performed with a great potential application in the identification of differentially expressed genes that may be correlated with the differential response of apricot against PPV.
