title: DNA barcoding of  arid wild plants using rbcL gene sequences.
abstract: DNA  barcoding is currently gaining popularity due to its simplicity and high  accuracy as compared to the complexity and subjective biases associated with  morphology-based identification of taxa. The standard chloroplast DNA barcode  for land plants recommended by the Consortium for the Barcode of Life (CBOL)  plant working group needs to be evaluated for a wide range of plant species. We  therefore tested the potential of the rbcL marker for the identification  of wild plants belonging to diverse families of arid regions. Maximum  likelihood tree analysis was performed to evaluate the discriminatory power of  the rbcL gene. Our findings showed that using rbcL gene sequences  enabled identification of the majority of the samples (92%) to genus level and  only 17% to species level.
