Phosphoethanolamine N-methyltransferase (encoded by the PEAMT gene) catalyzes the methylation of phosphoethanolamine to produce phosphocholine, which is dephosphorylated to free choline. Choline is the substrate for glycine betaine synthesis, which can improve the salt tolerance of plants. A 1688 bp cDNA of SlPEAMT was isolated from the halophyte Suaeda liaotungensis. Real-time quantitative PCR showed that SlPEAMT expression was induced in S. liaotungensis under salt stress. An 897 bp fragment… CONTINUE READING
