Barley DNA-binding methionine aminopeptidase, which changes the localization from the nucleus to the cytoplasm by low temperature, is involved in freezing tolerance

▶ Finding novel nuclear localized and DNA-binding methionine aminopeptidase (MAP) in barley. ▶ Translocation of MAP protein from nuclear to cytoplasm by low temperature. ▶ Overexpression of MAP confers strong freezing tolerance to Arabidopsis.
