Transcriptome profiling of the endophyte Burkholderia phytofirmans PsJN indicates sensing of the plant environment and drought stress. Transcriptome profiling of the endophyte Burkholderia phytofirmans PsJN indicates sensing of the plant environment and drought stress

Whole transcriptome sequencing of B. phytofirmans PsJN colonizing potato (Solanum tuberosum L.) plants was used to analyze in planta gene activity and in the response of strain PsJN to plant stress in three different time points. The transcriptome of PsJN colonizing in vitro potato plants showed a broad array of functionalities encoded on the genome of strain PsJN. Our study indicates that endophytic B. phytofirmans PsJN cells are active inside plants. Moreover, the activity of strain PsJN is affected by plant drought stress, it senses plant stress signals and adjusts its gene expression accordingly.
