Signals are the averages of two biological replicates (avg. signal) for both control (17°C) and cold stress (4 days at 4°C) and fold changes represent the ratios of stress to control average signals. For a given probeset, potato best match refers to the best hit (highest perfect alignment score) between tomato target vs. potato TIGR TA entry as determined by the Global Match File. Adjusted P-value (Adj.P.Val) estimates false positives and refers to Benjamini-Hochberg's multiple test correction of the false discovery rate.
