Chitinase is an important pathogenesis-related protein in plants, and it can accumulate when induced by salicylic acid (SA) or other elicitors. Here, we found that chitinase mRNA levels were 4.5-times greater when peanut seedlings were sprayed with 1.5 mM SA, as compared to water. The upstream promoter sequence of the chitinase gene was cloned by TAIL-PCR and the potential cis-regulatory elements in this promoter were predicted by the cis-element databases PLACE and plantCARE.
