Project description:The transcriptome of the planarian Schmidtea mediterranea is not well characterized. We have used RNA-Seq to characterize the transcriptome in both sexual and asexual strains of S. mediterranea from both untreated and irradiated animals. Moreover, we have performed RNA-Seq on RNA purified from FACS sorted neoblasts and differentiated cells. Together these studies expand our understanding of the planarian transcriptome and have identified strain-specific, neoblast-specific, and conserved transcripts.

Together these studies expand our understanding of the planarian transcriptome and have identified strain-specific, neoblast-specific, and conserved transcripts. RNA-Seq was performed on RNA isolated from untreated and irradiated S. mediterranea animals from both the sexual and asexual strains, on FACS purified X1 neoblasts, X2 neoblasts, and Xins differentiated cells. One of the raw data files for GSM847465 is missing. The fasta file is provided at http://genome.vcell.uchc.edu/GenomeData02/Graveley_Lab_Public_Data/Planarian/S.mediterranea_SexNIRmRNA3.fa.gz
Project description:The use of Biological Control Agents (BCAs) to cope diseases has received considerable attention owing to its high efficiency and environmental safety. The aim of our study was to investigate the potential role of the Pseudomonas mediterranea pre-treatments in the response of lemon [Citrus limon (L.) Burm. f.] against mal secco, this being a devastating citrus disease caused by the fungus Plenodomus tracheiphilus. RNAseq analysis revealed that the fungus induced a marked reprogramming of the transcriptome, but P. Mediterranea pre-treatments strongly reduced lemon leaf transcriptome modifications and limited the amount of the fungus DNA inside the plant tissue. Furthermore, P. mediterranea prevented the down regulation of the genes involved in the effector triggered immunity (ETI) and the deregulation of genes involved in the main phytohormone’s biosynthesis and perception. As far as we know, this work represents the first report on the analysis of P. tracheiphilus-lemon plant-BCA interaction at molecular level.
Project description:Investigation of differences in gene expression between two strains of the planarian Schmidtea mediterranea. The sexual strain are cross-fertilizing hermaphrodites with reproductive organs that develop post-embryonically and the asexual strain reproduces exclusively by transverse fission and fail to develop reproductive organs.
