Gene Expression Analysis of a Late Embryogenesis Abundant Gene from Salvia miltiorrhiza Bunge / 中国生物工程杂志

According to the sequence of SmLEA gene,a DNA fragment of 1 038 bp upstream of the coding sequence of SmLEA gene was amplified by DNA walking with the genomic DNA of Salvia miltiorrhiz as the template.Sequence analysis showed that the fragment contained some putative cis-elements relating to abiotic stress,ABA,seed specific expression.So the S.miltiorrhiz seedings was treated with 100?mol/L ABA,200mmol/L NaCl,4℃,and subjected to dehydration.The real-time PCR showed that expression levels of SmLEA was increased obviously,which was in accordance with the sequence analysis.
