[Proteomic analysis of the salt tolerance mutant of wheat under salt stress].
Two dimensional electrophoresis was used to analyse the proteome of the salt-tolerant mutant of wheat (RH8706-49) and the salt-sensitive mutant of wheat (H8706-34) which had been treated by 1% NaCl for 72 hours. After being analysed by MALDI-TOF-MS and Mascot software, the qualitative and quantitative differences were identified between the two materials for five candidate proteins: H+-transporting two-sector ATPase, glutamine synthetase 2 precursor, putative 33 kD oxygen evolving protein of photosystem II and ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit. These five proteins are all belong to chloroplast proteins. They are likely to play a crucial role in keeping the function of the chloroplast and the whole cells when the plant was under salt-stress.
