Model of the Rhizobium tropici CIAT 899 transcriptomic response under salt stress. RNA-seq studies indicate that in the presence of high concentration of salt CIAT 899 increase the transcription of nodulation genes and the synthesis of NF. Transcriptional activation (+) or inhibition (−) of other biological processes associated with the presence of salt supports the hypothesis that salt-dependent production of NF could be a special R. tropici CIAT 899 strategy to ensure nodulation under salt stress conditions.
