Abstract

For my contribution to the research on Artemisia tridentata, I identified and analyzed Cytokinin Response Factors (CRFs) from the recent reference genome3. CRFs have been found to potentially be regulators of the developmental processes within vascular tissues and they also play an important role in environmental stress response. This makes CRFs essential in the regulation of plant development and have impacts on a plant’s drought stress tolerance. The understanding of these pathways can lead in many directions including more sustainable, drought resistant species. I hypothesized that due to an evolutionary history with whole genome duplications, CRFs in the Artemisia tridentata genome may be duplicated. To test this hypothesis, I Identified A. tridentata cytokinin response factor proteins and reconstructed the phylogeny of CRFs. The finding of only twelve CRFs indicates there is no retention of duplicated CRFs in the A. tridentata genome.
