Transcriptome analysis of Arabidopsis thaliana shoots and roots, exposed to PEG-induced osmotic shock, PEG+Histidine, PEG+SHAM [20191204_130529_uLox_PEG_Shock]

In order to better understand the context of root water stress and its relationship to other stresses, I undertook an evaluation of osmotic water stress by transcriptome analyses. Whole transcriptome MARSeq (Diego Adhemar Jaitin, 2017) analysis can enable us to study the changes in gene expression (changes in transcript prevalence) in depth under different treatments. It is a cost effective method to develop transcriptional activity. It uses relatively small amounts of RNA and reads sequences from the 3’-polyA containing end. This method can reveal underlying trends that can help us understand the less obvious processes happening in our system. To carry this out I processed whole transcriptome data separately from WT and µlox seedling roots and shoots under 30% PEG -induced osmotic shock and control conditions and after 0, 1, 2, 3 h. µlox Arabidopsis thaliana seedlings were exposed to 30% PEG, for 0, 1, 2, 3 h, and root RNA was extracted sequenced using the MARSeq protocol.
