Outline of Final Research Achievements

We searched proteins which involved in frost tolerance in potato plants by comparative analyses between frost-susceptible cultivated species and frost-tolerant wild species. Values of freezing tolerance of S. tuberosum cv. Nishiyutaka were -1.4C and -2.5C for non-acclimeted and cold-acclimated leaves, respectively. Those of S. acaule and S. commersonii were -3.3C and -3.7C before acclimation, and -4.8C and -5.8C after cold-acclimation. A shotgun proteomics analysis on soluble fractions suggested that some proteins which were expected to involve in cellular antioxidant activities were accumulated characteristically in the two wild potato species. In addition, we identified several plasma membrane protein bands which showed quantitative changes during cold acclimation for each species in an SDS-PAGE analysis.
