Salt stress is a common side-effect in plants impacted on plant growth, metabolism and productivity. A. annua L. is one of the well-known antimalarial plants, biosynthesized artemisinin in its leaf, now introduced in all-over the world. In this article, we have analyzed the A. annua L. ESTs under salt stress and predicted cis-regulatory elements, roles in abiotic stress signaling. Further, the predicted abiotic stress responsive factors were analyzed in order to their function annotations as compare to the genome of Arabidopsis thaliana. 11 EST-contigs assembled from 127 were 29 signals elements were identified by CAP3 program. In order to evaluate accuracy of the identified factors, gene ontology functions were performed. GOBP analysis enriched the genes (85.71%) as the response to abiotic signaling. The co-expression analysis was revealed by gene investigators and String 10.0, these factors-oriented genes had at least 0.40 correlations and 0.7 mutual connection. In projected PPI network, the recognized factors belong to plant hormone signaling and diterpene pathways. These factors (ABF1, APX CCC1, CPK6, JAZ1, MYC2) introduced as candidate genes responsive factors could be overexpressed in A. annua L. plants either alone or in a shuttle may led the good metabolism and higher artemisinin content.
