ASES is 59% identical to Artemisia cyclase cDNA clone cASC125, 50% identical to epi-cedrol synthase from A. annua, 48% identical to amorpha-4, 11-diene synthase from A. Annua, 39% identical to the 5-epi-aristolechene synthase from tabacco, 38% identical to vetispiradiene synthase from H. Muticus, 41% identical to the δ-cadinene synthase from cotton. The coding region of cDNA was cloned into procaryotic expression vector pET30a and overexpressed in E. coli BL21 (DE3). The cyclase proteins extracted from bacterial culture were found largely in the insoluble protein fraction. The tissue specific expression patterns were analyzed by RT/PCR.

Seven thirdorder seismic sequences can be recognized from bottom to top in the Paleogene in the Wushi sag, which consist of a depositional sequence from transgression to regression as a whole and correspond to different stages of structural evolution. Sequences developed in different stages of structural evolution are different in filling sequence and distribution of sedimentary system. Multiphase structural evolutions result in development of source rocks and reservoir and cap rocks in various parts of the sag. The sequence 2-4 deposited in strong chasmic stage have the best source rocks and sealing conditions as well as various favorable reservoirs, thus are the most favorable targets for obtaining discoveries in this sag.
