Functional genomics approaches, which use combined computational and expression-based analyses of large amounts of sequence information, are emerging as powerful tools to accelerate the comprehensive understanding of cellular metabolism in specialized tissues and whole organisms. As part of an ongoing effort to identify genes of essential oil (monoterpene) biosynthesis, we have obtained sequenc...

we studied the antioxidant activities of the essential oils of zataria multiflora boiss. (zeo) and bunium persicum (boiss.) b. fedtsch (beo) in mixed form on linseed oil using (dpph•), ­(­abts•+), h2o2 scavenging, and reducing power assays. after calculation of ic50 for zeo and beo separately, interactions of the essential oils were investigated at the form of mixture and the results were given...
