Analysis of reversibility of transcriptome responses to abiotic stress conditions in Arabidopsis thaliana

Plants acclimate to environmental fluctuations by transitory reconfigurations the homeostatic network. Primary studies suggested that transcriptome responses to deal with fluctuations in light intensity and temperature tend to reversibility after stress removal in the model plant Arabidopsis thaliana. To gain more insight into this pattern in the context of acclimation, RNA-Seq analysis were conducted in Arabidopsis thaliana after different abiotic stress treatments consisting in high light (HL), high humidity, drought, heat, cold and combinations among factors or after recovery periods. Our transcriptome study is in line of a general pattern wherby transcriptome changes in response to adverse environments are prone to return to the basal state during the de-acclimation phase. In this study, the dynamics of acclimation responses in Arabidopsis thaliana at transcriptional level has been conducted by comparing transcriptome profiles of plants exposed to wide range of abiotic stress factors applied individually or simultaneously to those of plants after a period of recovery.
