|
| Treatment protocol |
At day 18, the nutrient medium for the treatment plants was replaced with 1.0 X modified Hoagland’s with 150 mM Sodium Chloride (NaCl) (pH 6.5), which represented a salinity concentration known to be toxic to chickpea (unpublished data; Munns 2002). Root tissues were collected from five treatment plants at 24 h post-treatment (hpt).
|
| Growth protocol |
The treatment plants were cultivated in a hydroponic system using 50 L plastic crates. Forty holes (8 x 5 grid) of 5 cm diameter were drilled in the crates’ lid and rock wool plugs were placed in them. The germinated seeds were transplanted in alternate plugs within the crate. The seedlings were watered normally from above for four days. The following day, the crates were filled with 0.5 X modified Hoagland’s nutrient medium (pH 6.5; Taiz and Zeiger 2002). The medium was aerated using two aquarium pumps. The nutrient medium was subsequently replaced with 1.0 X Hoagland’s solution (pH 6.5) after a further seven days.

| Treatment protocol |
At day 18, the nutrient medium for the control plants was replaced with just 1.0 X modified Hoagland’s medium (pH 6.5). Root tissues were collected from five control plants at 24 h post medium change.
|
| Growth protocol |
The control plants were cultivated in a hydroponic system using 50 L plastic crates. Forty holes (8 x 5 grid) of 5 cm diameter were drilled in the crates’ lid and rock wool plugs were placed in them. The germinated seeds were transplanted in alternate plugs within the crate. The seedlings were watered normally from above for four days. The following day, the crates were filled with 0.5 X modified Hoagland’s nutrient medium (pH 6.5; Taiz and Zeiger 2002). The medium was aerated using two aquarium pumps. The nutrient medium was subsequently replaced with 1.0 X Hoagland’s solution (pH 6.5) after a further seven days.

| Description |
The data submitted represents the mean data from three biological replications that inlcuded dye swaps between control and treatment samples
|
| Data processing |
Data transformations consisted of a local background correction (mean intensity of background was subtracted from mean signal intensity for each spot), omitting flagged spots, Lowess normalisation of the entire population, creating a Cy5/Cy3 mean signal ratio, taking a shifted log (base 2), and combination of duplicated spot data. To identify differentially expressed (DE) genes, expression ratio results were filtered to eliminate genes whose 95% confidence interval for mean fold change (FC) did not extend to 2-fold up or down, followed by Students t test with False Discovery Rate (FDR) multiple testing correction to retain only genes in which expression changes versus untreated control were significant at P < 0.05.
