title: Development of genetic markers for Ochradenus  arabicus (Resedaceae), an endemic medicinal plant of Saudi Arabia.
abstract: Some species of the genus Ochradenus are  difficult to identify based on morphological markers. Similar limitations are  found for biochemical markers. We developed genetic markers based on DNA  sequences for Ochradenus arabicus, which is an endemic plant to Saudi  Arabia, locally utilized as a medicinal shrub. The internal transcribed spacer  sequence of nuclear ribosomal DNA and chloroplast (rpoB and rpoC1)  markers were more informative than other chloroplast DNA markers. Based  on these markers, we were able to discriminate this species from another  species of the same genus (O. baccatus) that is widely distributed in  Saudi Arabia, despite a high degree of morphological similarity. These genetic  markers facilitate its identification, even when acquired in a dried state from  local markets.
