| Abstract: | Change in betaine aldehyde dehydrogenase(BADH)activity of Puccinellia chinampoensis under sall stress was explored and the conserved sequence of BADH was amplified using degenerate primers.The results demonstrated that the conserved sequence was 438 bp in length,which was deduced coding 145 amino acids. The deduced products contained the conserved motif of aldehyde dehydrogenase which was V[T/S]LELGGKSP and the Cys associated with aldehyde dehydrogenase function.The gene accession nucleotide sequence num- ber in GenBank was EF095710. |
