  1. a *, ** and *** indicate significant F values for the plant line effect and line × treatment interaction at the 0.05, 0.01 and 0.001 levels, respectively. An additional 58 salt-responsive AtNHX1 influenced transcripts with unclear functional assignment are not presented and can be found in Additional File 1
  2. b the specific treatment influenced by AtNHX1 for cases of significant interaction, or 'All' for cases where only the plant line effect was significant.
  3. c transcript intensity of the three plant lines for the treatment of interest, with the average expression value of all treatments used when only plant line effect was significant.
  4. d transcript intensity of the nhx1 line is in bold font for cases where the expression level is higher compared to the other lines, normal font signifies reduced expression.
  5. e At3g54810 is represented twice because it showed a significant influence of AtNHX1 at both one week and two weeks of salt treatment, with alternate relative levels of expression of the nhx1 line
