For each spot, the name of the homologous sequence, the functional category and the average CA/NA abundance ratio across the six populations are listed. Spots with cold acclimated (CA) to non-acclimated (NA) abundance ratio ≤− 1.5 and with t-test, P < 0.05 in at least five populations are presented. In cases when homologous sequences were detected at different positions on the gels, the spot with the lowest CA/NA ratio is presented. The exhaustive list of polypeptides up-regulated in response to cold acclimation is provided in Additional file 4: Table S4b
