Transcriptome changes in Arabidopsis thaliana infected with Pseudomonas syringae during drought recovery

Abstract Field-grown plants experience cycles of drought stress and recovery due to variation in soil moisture status. Physiological, biochemical and transcriptome responses instigated by recovery are expected to be different from drought stress and non-stressed state. Such responses can further aid...

Physiological, biochemical and transcriptome responses instigated by recovery are expected to be different from drought stress and non-stressed state. Such responses can further aid or antagonize the plant’s interaction with the pathogen. However, at molecular level, not much is known about plant-pathogen interaction during drought recovery.
