摘 要:[Objective] The aim was to study the cloning and sequence analysis of rbcS gene of wild barley under salt stress. [Method] The tender leaf blade of wild barley under salt stress was taken as the experimental material. The primers were designed according to the homology of rbcS gene sequences of wheat and barely in Genbank; then PCR amplification,recovery,ligation,transformation and sequencing of rbcS gene were carried out. [Result] Two rbcS genes including rbcS1 and rbcS2 with the length of 1 252 and 908 bp respectively were cloned from the barely genome. rbcS1 and rbcS2 were both composed by two exons and one intron. The exons length of the two genes was the same of 525 bp,encoding 174 amino acids,and the homology between them was 96%; however,the intron length of rbcS1 and rbcS2 was 448 and 107 bp respectively.
