The RNA arbitrarily primed PCR （RAP-PCR） approach was used to identify those genes that are differentially expressed in response to changing salinity in Halobacterium NRC-1. 81 primers were used to scan two different RNA pools derived from cultures of 17% and 30% NaC1 concentrations. On average, each RT-PCR reaction yielded more than ten bands on the agrose gel. Of the approximately 900 bands that were generated by 81 RT-PCR reaction pairs, 15 differentially-expressed bands were obtained. The results would be useful to understand the adapt...
